What is the solution to y + 7 = -9 A. y = -16 B. y = -2 C. y = 2 D. y = 16
Helen [10]

Answer:

A. y = -16

Step-by-step explanation:

Hello!

What we do to one side of the equation we have to do to the other.

y + 7 = -9

We have to get y by itself so we have to get rid of the seven by doing the opposite of what it says

The opposite of addition is subtraction so we subtract 7 from both sides

y + 7 - 7 = -9 - 7

Solve

y + 0 = -16

Simplify

y = -16

The answer is A. y = -16

Hope this helps!

Answer:

Below in bold.

Step-by-step explanation:

First find the height by use Pythagoras theorem on the right triangle:

h = sqrt (5^2 - 4^2)

= sqrt 9

= 3.

Volume of the prism = area of the triangle * length

= 1/2 * 3 * 4 * 10

= 1/2 * 12 * 10

= 60 cm^3.

Total area = area of 2 triangles + area 0f 3 rectangles

= 2 * 1/2 * 3 * 4 + 3 * 10 +  4 * 10 + 5 * 10

= 12 + 30 + 40 + 50

= 132 cm^2.

In the first 10 minutes , the distance cover is 1 miles every minutes

So, for 10 minutes , total distance cover by John = 10 × 1 = 10 miles

Again ,

John cover distance of 0.5 miles for every minutes , he travel for next 10 min

So, for next 10 min, total distance cover by John = 10 × 0.5 = 5 miles

So, The total distance cover by john = 10 miles + 5 miles = 15 miles
