Answer:
No solution
Step-by-step explanation:
System of Linear Equations given :
[1] 6x-2y=8
[2] 1-3x+y=-4
Equations Simplified or Rearranged :
[1] 6x - 2y = 8
[2] -3x + y = -5
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = 3x - 5
// Plug this in for variable y in equation [1]
[1] 6x - 2•(3x-5) = 8
[1] 0 = -2 => NO solution
what decimal part of one dollar is two dimes
Answer: Tenths place.
Step-by-step explanation:
0.20
The 2 is part of the tenths place.
Answer:
$0.20
Step-by-step explanation:
1 penny = $0.01
1 nickel = $0.05
1 dime = $0.10
1 quarter = $0.25
Two dimes = $0.20
Or 1/4 of a dollar
Or 0.2 because you don't need to add a 0 at the end of .2 or the $ sign.
This figure is the pre-image of a prism that has undergone a dilation with a scale factor of 3/4.
What is the surface area of the image after the dilation?
185 5/8 m²
219 3/8 m²
247 1/2 m²
292 1/2 m²
The surface area of the image after the dilation is 219 3/8 m²
What is an area?Area is the amount of space occupied by a two dimensional shape or object.
The surface area of the prism = 2(0.5 * 5 * 12) + (5 * 11) + (11 * 12) + (13 * 11) = 390 m²
The surface area of the image after the dilation = scale factor² * 390 m² = (3/4)² * 390 m² = 219 3/8 m²
The surface area of the image after the dilation is 219 3/8 m²

Which phrase describes the algebraic expression 6x?
O the quotient of 6 and a number
O the difference of 6 and a number
O the product of 6 and a number
O the sum of 6 and a number
Answer:
The product of 6 and a number
Step-by-step explanation:
There isn't any "real" mathematics needed to find the answer, just common background knowledge:
6x = 6 times x,
and product is referencing multiplication
(Since quotient is for division, difference for subtraction, and sum for addition)
considering we need to represent an expression which uses multiplication in words, the correct answer is:
O the product of 6 and a number

Show that 9.1 is not a solution of the equation n-6.4 = 2.61. Then find
the solution
Answer:
The solution is 9.01.
Step-by-step explanation:
To prove that 9.1 isn't the solution we have to plug 9.1 into the equation. By replacing n with 9.1 we get 2.7 which isn't equal to 2.61.
To find the solution we must add 6.4 to both sides of the equation.

Answer:
Area is 30cm^2 if thats what your asking
Step-by-step explanation:
Answer:
X = 5
Step-by-step explanation:
You need to use the Pythagorean theory to solve this question.
[tex] {13}^{2} = {x}^{2} + {(x + 7)}^{2} [/tex]
[tex]169 = {x}^{2} + ( {x}^{2} + 14x + 49)[/tex]
[tex]169 = 2 {x}^{2} + 14x + 49[/tex]
[tex]0 = 2 {x}^{2} + 14x + 49 - 169[/tex]
[tex]0 = 2 {x}^{2} + 14x - 120[/tex]
Now simply the equation by dividing everything by 2.
[tex]0 = {x}^{2} + 7x - 60[/tex]
[tex]0 = (x - 5)(x + 12)[/tex]
Now, you can find the possible solutions by setting each bracket to 0.
[tex]0 = x - 5[/tex]
[tex]5 = x[/tex]
OR
[tex]0 = x + 12[/tex]
[tex] - 12 = x[/tex]
However, a measurement on a triangle cannot be negative. Therefore, we can ignore -12 and say that the answer is x = 5.

are the degree measurements of each angle?
⚫️67.50 and 22.5°
⚫️22.5° and 90°
⚫️60 and 120°
⚫️135° and 45°
Answer:
90 for choice 1, 112.5 is for choice 2, 180 for choice 3, and 180 for choice 4.
Step-by-step explanation:
67.50 and 22.5 is a complementary angle because it adds up to 90 degrees.
22.5 and 90 added is 112.5 which is an obtuse angle
60 and 120 added is a supplementary angle because 60 + 120 is 180
135 and 45 is also a supplementary angle because 135+45 = 180

Laura kept a record of the number of minutes she spent at the gym this week.
Day Minutes
Monday 60
Tuesday 70
Wednesday 62
Thursday ?
How many minutes should she spend at the gym on Thursday in order to average 65 minutes a day for four days.
________ Minutes
she spends 68 minutes at the gym on Thursday in order to average 65 minutes a day for four days.
What is Average?The mean (also known as the arithmetic mean, which varies from the geometric mean) of a dataset is calculated as the sum of all values divided by the total number of values. This measure of central tendency is usually referred to as the "average".
Granted, Laura recorded how long she spent at the gym each day this week.
Let "x" represent the time she spent working out on Thursday.
Since,
Average = (sum of values)/ count of values
Thus, in our case
Average = (60 +70 +62 +x)/4
average is 65 minutes a day for four days.
65 = 192 +x)/4
192 +x = 260
x = 260-192
x = 68
Therefore, she spends 68 minutes at the gym on Thursday in order to average 65 minutes a day for four days.

tan(-315)
[?]
Answer:
the exact value of tan(-315) is 1
Answer:
The tangent of -315 is opp/adj = 1/1 = 1
Step-by-step explanation:
The angle -315 is in the 1st quadrant, in which we see a 45-45-90 triangle. Thus, this triangle has 'opposite side' = 1, 'adjacent side' = 1, and hypotenuse √2. The tangent of -315 is thus opp/adj = 1/1 = 1

Find x in circle O (The figure is not drawn to scale)
Answer:
20.5 degrees
Step-by-step explanation:
So when the arc is being made from two lines coming out from the center, the measure of the arc is the same as the angle of the lines.
So the measurement of 41 degrees for the arc is also the angle of line OB and line OC.
Now that center line is the diameter, which means it is 180 degrees
So you can find the angle of line OA and OB:
180 - 41 = 139
Then, to find x you need to recognize that OB and OA is actually the radius of the circle, which means they are the same length.
This makes it an isosceles triangle. So, the angle of OB and BA is the same as OB and BA. The measurement of all the angles in a truianbgle is 180 degrees, so to find the measurement of x, you need to subtract 139 from 180:
180-139 = 41
And then divide by two to find the remaining two angles:
41/2 = 20.5
and that is x :)
