Substitute the value for x into the original equation. Simplify using order of operations. If the statement is true, Jason’s solution for x is correct. If the statement is false, Jason’s solution for x is incorrect.Step-by-step explanation: (My answer)
1) Subtract 8.5 and 3.5, that equals 12.
[tex]8.5x - 3.5x = -78[/tex]
2) Multiply 78 and 12, that equals 6.5 .
[tex]\frac{12x}{12} = \frac{78}{12}[/tex]
3) Check your answer.
[tex]-8.5 (6.5) -3.5 (6.5) = -78[/tex]
Multiply 8.5 and 6.5, that equals 55.25. Next, multiply 3.5 and 6.5, that equals 22.75.Finally, you will need to subtract your answers. Subtract both 55.25 and 22.75.Once you've done that, the answer you should get is 78.
78 is equal to 78, that is your final answer and it is correct.
Let U = {9, 10, 11, 12, 13, 14} and A = {11, 13}. Determine whether the statement A⊂U is true or false and find A'.
a. false; A' = {11, 12, 13, 14}
b. true; A' = {9, 10, 11, 12, 14}
c. false; A' = {9, 12, 14}
d. true; A' = {9, 10, 12, 14}
Answer:
D; A⊂U is true and A'={9, 10, 12, 14}
Step-by-step explanation:
A={11,13}
Because those numbers are included in the statement U={9,10,11,12,13,14}, we can say that it's true that A belongs to U.
A' is the numbers of U not including A. So, it would just be U without the 11 and 13, or {9,10,11,12}

x=[tex]\geq[/tex]80-27
Step-by-step explanation:
there is needed atleast 80 tickets and you've given 27 so you would need a minimum of 53 tickets to make the inequilaty true
-3n-4n-17=25
What is n?
Answer:
-6
Step-by-step explanation:
add -3n and -4n= -7n
add 17 to 25
-7n=42
n=-6
can u guys please help I'm really behind in school I'm in 7th grade
The value of x is 42. Multiply the top and bottom by 6 because the numerator in the first fraction is 2 and the numerator for the second fraction is 12. When you multiply 2 by 6, you get 12. You have to do the same for the denominator. multiply 7 by 6. You get 42. The value of x is equal to 42. Hope this helps.
Answer:
42
Step-by-step explanation:
First, you cross multiply.
12 x 7= 84
2 multiplied by x will give you 2x.
Now, you have the equation below left:
84=2x
Then, you divide by 2 on both sides (in order to leave x by itself):
84/2= 42
x=42
Prove that when 2 lines intersect each other ,then the vertically opposite angles formed are equal.
plz help fast
Answer:
Because both lines intersect at one given point, this means that wherever they intersect both lines will have the same length on each side because that one point serves as the half way point between the intersection. meaning that if two lines cross and it creates the vertical angle of 150⁰ then by definition the side that is across that intersection point will also be 150⁰
Answer:
Step-by-step explanation:
If two lines i.e. AB & CD intersect each other. They have two pair of opp. angles.
i.e.
∠AOC,∠DOB,∠AOB,∠COB.
To prove :- ∠AOC=∠DOB & ∠AOD=∠COB
Proof :-
∠AOC+∠AOD=180 °
[linear pair] ___(1)
∠AOD+∠BOD=180°
[linear pair] ___(2)
from eq. (1) & (2)
∠AOC+∠AOD=∠AOD+∠BOD
i.e. [∠AOC=∠BOD]
Similarly [∠AOD=∠COB]
Hence proved.
Hope this helps

Find the Unit Rate on a 5-gallon bucket of paint that costs $68.75
Answer:
$13.75 per gallon
Step-by-step explanation:
To solve for any unit rate you use
[tex]\frac{1}{x} =\frac{5}{68.75}[/tex]
Cross multiply.
So 68.75 = 5x
Divide both sides by 5 to get x alone.
13.75 = x
Therefore 1 gallon equals $13.75

Rebecca writes 1/5 of a page in 1/14 minute. How many pages can she write in one minute? (fraction) pages per minute.
HELP I BEG!!
Answer:
She can write 2 pages and 4/5 extra.
Step-by-step explanation:
We know that she has already written for 1/14 of a minute. Now we need to turn that fraction into a whole, because the problem is asking for a whole minute.
___ x 1/14 = 1?
14
Now we take the 1/5, and multiply it by the 14 to see how much she writes in a minute.
1/5 x 14 = 14/5
Last we simplify.
14/5 = 2 4/5

Are x(3x) and 4x equivalent?
Answer:
They are not equivalent.
Step-by-step explanation:
x(3x) = 4x
x by itself = 1x
1x ( 3x ) = 4x
1x times 3x = 3x
3x = 4x is not equivalent.
Suppose that gas costs Big Ray $2.00/gallon and that he pays an attendant $100/day. Let C(x)
represent the total daily cost as a function of the price of the gas. Find the formula for C(x)
Answer:
C(x) = 2x + 100
Step-by-step explanation:
Here, we want to find the formula for C(x)
Here, x will be the number of gallons of gas
so per day, if x gallons of gas were consumed, the daily cost here will be x * 2 = $2x
Adding the cost for the attendant, we have 2x + 100
So the formula for C(x) will be;
C(x) = 2x + 100

Step-by-step explanation:
To solve the figure. You need to split the shape up with the lines shown.
Let's solve the top triangle first.
The formula to find the area of a triangle is y = 1/2(b*h)
So the base is 2+2+6 which equals 10. And the height is 4.
So y = 1/2(4*10)
PEMDAS solve parentheses first.
y = 1/2(40)
y = [tex]20cm^{2}[/tex]
Now solve the bottom left one.
y = 1/2(2*2)
y = 1/2(4)
y = [tex]2cm^{2}[/tex]
Now the bottom right triangle.
y = 1/2(6*2)
y = 1/2(12)
y = [tex]6cm^{2}[/tex]
And to solve area of a square is
y = b*h
y = 2*2
y = [tex]4cm^{2}[/tex]
And add all of it up to get
y = [tex]20cm^{2}+2cm^{2} +6cm^{2} +4cm^{2} = 32cm^{2}[/tex]
Area = [tex]32cm^{2}[/tex]
Solve the following equation.
X + 5 = 2x
Can some explain to me how to do this? I have to add one of these numbers to both sides of the equation but idk which one.
Answer:
x = 5
Step-by-step explanation:
Subtract x from both sides.
Your equation would look like this now:
5 = 1x
Divide both sides by 1.
x = 5
Hope you understand :)
Please consider Brainliest :)
[tex]x + 5 = 2x[/tex]
[tex]5 = 2x - x[/tex]
[tex]5 = 1x[/tex]
[tex]x = 5[/tex]
Let us check whether or not we have found out the correct value of x , by placing 5 in the place of x .
Which means :-
5 + 5 = 2 × 5
10 = 10
LHS = RHSHence proved that the value of x = 5 .
Therefore , 5 + 5 = 2 × 5 , ( x = 5 ) .

A fish swims at a rate of 8 feet per second. How far can the fish swim in 23
seconds?
Answer:
8(23) so 184
Step-by-step explanation:
Answer:
it would have traveled 184 feet
Step-by-step explanation:
Since the rate in which the fish is swimming is 8 feet per second and given that we have to figure out the distance in which it traveled in 23 seconds, we can just multiply 8× 23 to receive 184 feet in 23 seconds.
HELPPPPPPPP PLS!!!!!!!
Answer:
x = 8
Step-by-step explanation:
Set up an equation: (7x - 2) = (11x - 34)Combine like terms: 7x - 11x = 2 - 34Simplify: -4x = -32Divide each side by -4 to cancel out the -4 next to x. It should now look like this: x = 9I hope this helps!
4) The triangle on the right is an equilateral
Find the value of X and Y
Answer:
angle Y is 29 degrees
angle X is 120 degrees
Step-by-step explanation:
Well, if the triangle is an equilateral, then all the angles are equal to
60 degrees
that means the the angle at the top point is 60+31 = 91 degrees
the right point is 60 degrees
every triangle has 180 degrees total
180 - (91+60) = 29 degrees
NOW FORGET ABOUT THE EQUILATERAL FOR A BIT
180 = 31+x+29
simplify
180 = 60+x
subtract 60 from both sides
120 = x

Hope this helped!
Answer:
(x + 5)(x + 4)
Step-by-step explanation:
Assuming you require the expression to be factored
Given
x² + 9x + 20
Consider the factors of the constant term (+ 20) which sum to give the coefficient of the x- term (+ 9)
The factors are + 5 and + 4, since
5 × 4 = + 20 and 5 + 4 = + 9 , thus
x² + 9x + 20 = (x + 5)(x + 4) ← in factored form
If you travel 1000 feet in 5 minutes, what is your speed per minutes?
Answer: 200 feet
Step-by-step explanation:
1000feet/5feet= 200feet
Answer:
200 feet per minute
Step-by-step explanation:
Speed = Distance/Time
Since you want to find the "per minute", you would just divide the total distance by the number of minutes:
1000 feet / 5 minutes = 200 feet per minute
