Chris is going 10 mph. After 9 hours, Chris has gone 90 miles. Elena is going 14 mph. After 9 hours, she has gone 126 miles. 126 miles is 36 miles more then 90 miles.

10 \times 9 = 90 \\ 14 \times 9 = 126 \\ 126 - 90 = 36

The equation 9t = 27.99 models a constant rate situation.
jeka94

The value of 5t will be 15.55

Step-by-step explanation:

Given equation is;

9t = 27.99

As it is stated that the relationship is constant, therefore, we will find the value of t by dividing 27.99 by 9

t=\frac{27.99}{9}\\\\t=3.11

Now, we will put t=3.11 to find 5t.

5t=5(3.11)\\5t=15.55

The value of 5t will be 15.55

just olya [345]

Answer: 15 1/3 months

Step-by-step explanation:

Daniella has $210 in the bank, and her balance grows at a rate of $3 each month. This can be written as:

b = 3m + 210 ...... equation i

Lori has $187 in the bank and her balance grows at a rate of $4.50 each month. This can be written as:

b = 4.5m + 187 ....... equation ii

Combine both equations

b = 3m + 210

b = 4.5m + 187

3m + 210 = 4.5m + 187

4.5m - 3m = 210 - 187

1.5m = 23

m = 23/1.5

m = 15 1/3 months
