Answer:

The answer to your question is: One has saved $35 and the other $20

Step-by-step explanation:

Data

2 brothers

combined savings = $55

One brother has $15 more than the other

x = savings of one brother

y = savings of the other brother

- Process

Write an equation or two equations and solve it for x and y

(1) x + y = 55

(2) x = y + 15 Solve this system by substitution (2) in (1)

y + 15 + y = 55

2y = 55 - 15

2y = 40

y = 40/2

y = $ 20

x = 20 + 15

x = $ 35

Klio2033 [76]

Answer:

A cold front moved in last weekend.The average temperature change for each hour is 4.14 degrees per hour.

Solution:

Given that a cold front moved in last weekend. In 7 hours overnight, the temperate outside dropped 29 degrees

We have to find the average temperature change for each hour.

Average temperature change for 1 hour can be found out by dividing the temperature change for 7 hours (which is 29 degree) by 7 hours.

To compute the average, we need to divide the difference by the time needed, hence we get

Average temperature change for each hour = $\frac{\text {temperature change for } 7 \text { hours }}{7}$

$\frac{29}{7}=4.14$

So, the average temperature dropping is 4.14 degrees per hour.

Martin charges $15 for every 5 bags of leaves he raked last week and he raked 27 bags of leaves how much money did he earn

Luba_88 [7]

Answer:

$81

Step-by-step explanation:

First, find out how much he charges for raking 1 bag of leaves. The following equation can solve for the amount charged per bag.

[b = amount charged per bag]

15/5 = b

15/5 = 3

3 = b

This means he charges $3 for one bag.

Martin rakes 27 bags, so multiply 3 by 27 to find the total amount of money he earned

27(3) = 81

So, Martin earned $81 for raking 27 bags of leaves
