Answer: 2 numbers are 19 and 39
Step-by-step explanation:
<em>y = x + 20</em>
Equation: x + y + 20 = 78
⇔ x + y = 78 - 20
⇔ x + y = 58
⇔ y = 58 - x
So, we have:
x + 20 = 58 - x ( = y)
⇔ x + x = 58 - 20
⇔ 2x = 38
⇔ x = 19
⇒ y = x + 20 = 19 + 20 = 39

Since we are asked to find the rate of change from Monday to Wednesday, we are dividing by 2, since Monday is day 1 and Wednesday is day 3. 3 - 1 = 2.
1800 + 500 = 2300 calories consumed Tuesday.
2300 - 100 = 2200 calories Wednesday.
(2200 - 1800)/2 = 400/2 = 200 calories
25, 7*4 = 28 32-28=4 and 42/6=7*3 = 21 + 4 = 25

<em>We will assume the tent is in the shape of a triangular prism.</em>
The volume of a triangular prism can be found with the following formula, where 
is the width at the base, 
is the height, and 
is the length.
Substitute in the known values.
Simplify — use multiplication.
Simplify — use division.
The volume — or in this case, the amount of living space — is 
.
