Answer:
x = -16
Step-by-step explanation:
[tex]7(x-5) =9x-3 \\7x -35 = 9x - 3\\3- 35 = 9x - 7x\\-32 = 2x\\x = \frac{-32}{2}\\\huge \red{\boxed{x = -16}}[/tex]
Answer:
x = -16
Step-by-step explanation:
We are presented with the equation 7( x - 5 ) = 9x - 3 and we are asked to find the value of x. The first thing to do with equations with brackets is expand them out to make solving the equation easier. Then you want to collect all the 'x' terms to one side and all the numerical values to the other so we can make solving the equation easier.
→ 7( x - 5 ) = 9x - 3
⇒ Expand out the brackets
→ 7x - 35 = 9x - 3
⇒ Minus 9x from both sides to collect the 'x' terms
→ -2x - 35 = -3
⇒ Add -35 to both sides to isolate -2x
→ -2x = 32
⇒ Divide both sides by -2 to isolate x
→ x = -16
Quadrilateral EFGH is inscribed in a circle. If m∠F = 114° and m∠G = 78° then which of the following is the measure of ∠H?
Answer:
I think its 66
Step-by-step explanation:
Since if you draw it out properly F would be opposite of H.
Oppsite angles in a quadrilateral are supplementary(in a circle at least) meaning they add up to 180.
So 180-114= 66
So H=66

Ruby is visiting San Francisco. From her hotel she walks 4 blocks east and 3 blocks north to a coffee shop. Then she walks 7 blocks west and 6 blocks north to a museum. Where is the museum in relation to her hotel?
Answer:
Is that from RSM??
Step-by-step explanation:
Determine the minimum amount of packaging needed to completely cover a
triangular prism Oblerone bar with these dimensions: length 22.5 cm; triangular face
A right triangular prism has 3 rectangular faces.
If each of the edges of the triangular base measures 4.5cm,
and the length (the height) of the prism is 22.5cm,
the 3 rectangular faces (sides of the box) are rectangles,
22.5cm long and 4.5cm wide.
Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.
The total lateral surface area for the 3 rectangular sides of the box is
3(101.2 square centimeters)=303.75 square centimeters.
If the triangular faces of the box are triangles
with a base measuring 4.5cm and a height measuring 4.0cm,
the surface area of each triangular face is
(1/2)(4.5cm)(4.0cm)=9 square centimeters.
The surface area of the two triangular faces adds up to
2(9 square centimeters)=18 square centimeters.
The total surface area for the box is
303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,
and that rounds up to highlight 322 square centimeters.
NOTE:
The answer above is the one your teacher wants,
but there is a problem with this problem.
An equilateral triangle with sides measuring 4.5cm
would have a height of approximately 3.9cm.
The Pythagorean theorem says so.
However, the 4.0cm value makes the calculations easier.
Answer:
A right triangular prism has 3 rectangular faces.
If each of the edges of the triangular base measures 4.5cm,
and the length (the height) of the prism is 22.5cm,
the 3 rectangular faces (sides of the box) are rectangles,
22.5cm long and 4.5cm wide.
Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.
The total lateral surface area for the 3 rectangular sides of the box is
3(101.2 square centimeters)=303.75 square centimeters.
If the triangular faces of the box are triangles
with a base measuring 4.5cm and a height measuring 4.0cm,
the surface area of each triangular face is
(1/2)(4.5cm)(4.0cm)=9 square centimeters.
The surface area of the two triangular faces adds up to
2(9 square centimeters)=18 square centimeters.
The total surface area for the box is
303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,
and that rounds up to highlight 322 square centimeters.

An artist uses 60 pounds of clay to make 80 bowls. The ratio of pounds of clay she uses to the number of bowls she makes is a proportional relationship. Select all the true statements.
Answer:
With the given information we can find the unit rate at least
We know that the artist used 60 pounds of clay to make 80 bowls. If we divide those magnitudes, we would find the total number of pounds per bowl.
[tex]p=\frac{60}{80}=0.75 \ lb/bowl[/tex]
Therefore, the artist used 0.75 pounds per bowl.
We can also express the proportional relationship as
[tex]clay=0.75(bowl)[/tex]
Which indicates that the total number of pounds of clay represents 75% of the total number of bowls, that's the relation.

How long was Anthony's family gone? Complete the explanation of how the answer can be found. To find the answer, count hour(s) from 5:05 to 6:05. Then count minutes to 6:35. Then count minutes to 6:45 and minutes to 6:51. I add them all up to get that the Anthony's family was gone hour(s) and minutes. Anthony's family went out to dinner. They left at the time shown on the clock. They returned home at 6:51 P.M.
Answer:
Thus, the Anthony's family were away for 1 hour 46 minutes
Step-by-step explanation:
We are being told that Anthony's family went out to dinner and they left at the time shown on the clock (i.e 5;05 P.M) and they returned home at 6:51 P.M.
We are to calculate how long was Anthony's family gone
We all know that:
60 seconds = 1 minute
60 minutes = 1 hour
So from 5:05 to 6:05 = 60 minutes
From 6:05 to 6:35 = 30 minutes
From 6:35 to 6:45 = 10 minutes
From 6:45 to 6:51 = 6 minutes
Therefore ; to deduce how long was Anthony's family gone; we will have to sum up the values of the minutes from the above time- frames up;
So; (60 + 30 + 10 + 6 ) minutes
= 106 minutes
since 60 minutes = 1 hour
Then 106 minutes = 1 hour 46 minutes
Thus, the Anthony's family were away for 1 hour 46 minutes

What is the probability of rolling a number less than 4 and then rolling an odd number?
Write your answer as a percentage.
Answer:
rolling a number less than 4=
1,2,3 are less than 4 and a die is 6 sided so that will be 3/6 which in lowest terms is 1/2
1/2 as a percentage is 1/2*100=50%
rolling an odd number=
on a 6 sided die there are 3 odd numbers which are 1,3 and 5=
3/6 which in lowest terms is also 1/2
so 1/2*100=50%

Triangle ABC is rotated 180º using the origin as the center of rotation. On a coordinate plane, triangle A B C has points (negative 4, negative 3), (negative 5, negative 2), (negative 3, negative 2). Triangle A prime B prime C prime has points (4, 3), (5, 2), (3, 2). Which sequence of transformations will produce the same result? a translation up 4 and then a reflection over the y-axis a translation up 4 and then a translation right 6 a reflection over the x-axis and then a reflection over the y-axis a translation right 6 and then a reflection over the x-axis
Answer:
I just took the test on edge. The correct answer would be option C
Step-by-step explanation:
Hope this helped!
As per the question of the triangle, ABC is a rotation triangle and has an origin of the center as the location of rotation. The tringle is on a coordinated plane and the triangle ABC has points as 4, 3, 5, negative.
Thus option C that is a reflection over the y-axis.The A, B, C as a prime number of points (4, 3), (5, 2), (3, 2). The triangle is formed by the sequences of formations and transformations that will give out.
As the triangle is a right-angled triangle the ABC will be arranged in a series of sequences that shows the reflections from all the sides and hence the reflection is over the y axis and these are all related to the formation of the ABC.

Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .
Step 1) Use the area formula to find the length of the radius
A = (3.14 x r^2) / 4
3.14 = (3.14 x r^2) / 4
12.56 = 3.14r^2
r^2 = 4
r = 2 feet
Step 2) Use the perimeter formula to find the perimeter
C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 4) / 4) + 4
C = (12.56 / 4) + 4
C = 3.14 + 4
C = 7.14 feet

At a school fair, students were challenged to hit one of the small congruent circles on the large rectangular board with a ball. Find the probability of hitting any small circle. Type answer as a percent. *
Answer:
The probability of a student to hit any small circle is 4.66 %.
Step-by-step explanation:
In order to determine the probability of the students to hit the small circles, we need to calculate the are of the rectangle and the area of each circle. These are shown below:
area circle = pi*r² = pi*(3)² = 28.26 in²
area rectangle = 35*52 = 1820 in²
Since there are three circles and the students can hit any of those the probablity of hitting them is given by the area of one circle multiplied by 3 and divided by the area of the rectangle.
p = [(3*area circle)/(area rectangle)]*100%
p = [(3*28.26)/1820]*100 = 4.66 %

What is the probability of picking a prime number and then picking a prime number?
Simplify your answer and write it as a fraction or whole number.
Answer:
1/6
Step-by-step explanation:
There are 4 cards, 2 of which are primes
P(prime) =number of primes/total
= 2/4 = 1/2
Keep the card, now we have 3 cards, 1 of which is a prime
P(prime) =number of primes/total
= 1/3
P(prime, keep , prime) = 1/2*1/3 = 1/6
