A. The relationship can be expressed as n=5.25t. True or False
B. The graph of the equation is a straight line through (0,0). True or False
C. The unit rate is 5.75. True or False
Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3
The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.
What is the equation?More than one variable may be present inside a linear equation.
An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
13 = -3 + z
Since, A + B = B + A
Thus, -3 + z can be written as z - 3
So, 13 = z - 3
Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".

Brand 1 of antifreeze claims that it can withstand temperatures of –62°C. Brand 2 of antifreeze claims that it can withstand temperatures 5°C below those of Brand 1. Which expression represents the temperatures Brand 2 can withstand?
Answer:
-62c - 5c = -67c
Step-by-step explanation:
(Brand 1 ) -62c (Brand 2 is 5c lower, so it is negative or minus) -5c = (Do the math and it's -67c)

I need help with this!!!!!
Answer:
A) 4(7+x)=64
B) 4x+7=64
Step-by-step explanation:
A
4(7+x)=64
*Disturabute 4 to (7+x)*
28+4x=64
*Subtract 28 on both sides*
4x=36
*Divide by 4*
x=9
**If you do a Check it works*
B
4x+7=64
*Subtract 7*
4x=57
*Divide by 4*
x=14.25
**If you do a Check this also works**
Hope This Helps!!!
