After a power failure, the temperature in a freezer increased at an average rate of 3.5 °F per hour. The
total increase was 31.5 °F. Enter and solve an equation to find the number of hours until the power was
restored. Let x represent the number of hours it takes for the temperature to increase to 31.5 °F.
Answer:
equation: 3.5x=31.5
number of hours: 9
Step-by-step explanation:
31.5/3.5=9
Therefore,
x=9, x=number of hours, number of hours=9

Answer:
A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.
For example we have y=5x−8 and we can substitute this value of y in the other equation
4x+3y=33
4x+3(5x−8)=33 we can solve now for x
4x+15x−24=33
19x=33+24
19x=57
x=5719=3.
y can be obtained from the first equation
y=5x−8
y=5⋅3−8=15−8=7
Then x=3 and y=7.
Step-by-step explanation:
Answer:
x = 3
y = 7
Step-by-step explanation:
y = 5x - 8 ---------------(I)
4x + 3y = 33 ------------(II)
Substitute y = 5x - 8 in equation (II)
4x + 3 (5x - 8) = 33
4x + 3*5x - 8*3 = 33
4x + 15x - 24 = 33 {Combine like terms}
19x - 24 = 33 {Add 24 to both sides}
19x = 33 + 24
19x = 57 {Divide both sides by 19}
x = 57/19
x = 3
Substitute x = 3 in equation (I)
y = 5*3 - 8
y = 15 - 8
y = 7
6 + -4 =
-8 - (-10) =
-7 + 3 =
Step-by-step explanation:

Answer:
See Explanation
Step-by-step explanation:
See comment for correct presentation of the question
Given
[tex]Expression = 40\% * 75[/tex]
[tex]Priya = \frac{2}{5} * 75[/tex]
Required
Is Priya correct?
We start by simplifying the expression.
[tex]Expression = 40\% * 75[/tex]
Express 40% as fraction
[tex]Expression = \frac{40}{100} * 75[/tex]
Simplify fraction: Divide numerator and denominator by 20
[tex]Expression = \frac{40/20}{100/20} * 75[/tex]
[tex]Expression = \frac{2}{5} * 75[/tex]
By comparing:
[tex]Expression = \frac{2}{5} * 75[/tex]
and
[tex]Priya = \frac{2}{5} * 75[/tex]
We can conclude that Priya is correct because:
[tex]40\% = \frac{2}{5}[/tex]
is (3,4) a solution to the linear equation y=4x-8? Yes or No?
Answer:
Yes
Step-by-step explanation:
To find if the point (3,4) a solution to the linear equation y=4x-8 you need to substitute (3,4) into y=4x-8
(x,y)
(3,4)
x=3 and y=4
Subistute:
4=4(3)-8
4=12-8
4=4 which is correct so the answer is yes (3,4) is a solution for y=4x-8

Solve for X
1) 8(1 + 5x) + 5 = 13 + 5x
Answer:
X=0
Step-by-step explanation:
[tex]8(1 \times 5x) + 5 = 13 + 5x \\ 8 + 40x + 5 = 13 + 5x \\ 40x + 13 = 13 + 5x \\ 40x - 5x = 13 - 13 \\ 35x = 0 \\ x = 35 \times 0 \\ x = 0[/tex]
The solution to the equation is x = 0.
Here, we have,
Let's solve the equation step by step:
Distribute the 8 to the terms inside the parentheses:
8 + 40x + 5 = 13 + 5x
Combine like terms on both sides of the equation:
40x + 13 = 5x + 13
Subtract 5x from both sides to isolate the variable terms on one side:
40x - 5x + 13 = 5x - 5x + 13
Simplifying:
35x + 13 = 13
Subtract 13 from both sides to isolate the variable term:
35x + 13 - 13 = 13 - 13
Simplifying:
35x = 0
Divide both sides of the equation by 35 to solve for x:
35x/35 = 0/35
Simplifying:
x = 0
Therefore, the solution to the equation is x = 0.

Divide 55 in a ratio 3 : 7
Need help please
Answer:
16.5 : 38.5
Step-by-step explanation:
sum the parts of the ratio, 3 + 7 = 10 parts
Divide the amount by 10 to find the value of one part of the ratio.
55 ÷ 10 = 5.5 ← value of 1 part of the ratio, then
3 parts = 3 × 5.5 = 16.5
7 parts = 7 × 5.5 = 38.5
55 in the ratio 3 : 7 is 16.5 : 38.5
