Answer:

Step-by-step explanation:

1) x + 7 = 12

Add the additive inverse of 7  = -7 to both sides

x + 7 - 7 = 12 - 7

x + 0 = 5

x = 5

2) 7a = -28

Divide both sides by 7

7a/7 = -28/7

a = -4

3)\frac{y}{8}= -3\\\\

Multiply both sides by 8

\frac{y}8}*8=-3*8\\\\y=-24

Can someone help me with this?
Mandarinka [93]

Answer:

Step-by-step explanation:

Area of rectangle = length * width

                             = (x + 4) (5x)

                             = x *5x + 4 *5x

                            = 5x² + 20x

Perimeter of rectangle = 2*(length + width)

                                     = 2*(x + 4 + 5x)

                                     = 2*(6x + 4)

                                   = 2*6x + 2 *4

                                     = 12x + 8

Your friend is 1.2 times taller than you. Your friend is 64.5 inches tall. How tall are you?
Andru [333]
You are X, if your friend is 1.2 times taller than you= 1.2X
That's why 64.5=1.2X
                   X=53.75
But you should write 53.8 inches tall. Because there is one number after point.
<span>As a result, you are 53.8 inches tall

Describe a relationship in which it would be reasonable to have a negative number in the domain or
Aliun [14]

Answer:

Relationship between temperature at different times of the day during the Winter period in places like Alaska and Minnesota in the USA.

Step-by-step explanation:

An example of a relationship that would have a negative number in the domain or range would be the relationship between the temperature at different times of the day during the snow period in the winter. It's well known that in places like Alaska and Minnesota in the USA, that during the winter when there's very heavy snow, the average temperature is usually below 0°C. The temperature is the dependent variable and is most likely negative in those 2 states and thus the range would have negative numbers.
