For the same amount set up two equations set equal to each other.
$70h + 130 = 80h + $40
Subtract 80h from both sides
-10h + 130 = 40
subtract 130 from both sides
-10h = -90 divide both sides by -10
h = 9 hours

CHECK
70(9) + 130 = $760 
80(9) + 40 = $760

Answer:

9 hours

Step-by-step explanation:

Let for x hours the amount charged by Abe and Gabe is same.

Given,

In fixing by Abe,

Fixed cost  = $ 130,

Additional cost per hour = $ 70,

So, the total charge for x hours = 130 + 70x

In fixing by Gabe,

Fixed cost = $ 40,

Additional cost per hour = $ 80,

So, the total charge for x hours = 40 + 80x

For same charge,

130 + 70x = 40 + 80x

70x = 40 + 80x - 130

70x - 80x = -90

-10x = -90

⇒ x = 9

Hence, it will take 9 hours for both Abe and Gabe to cost the same amount

Match the following items.
Novosadov [1.4K]

The Matchup are:

1. 1/3(24+15)=1/3•24+1/3•15 -  distributive property

2. 101+(29+417) = (101+29) + 417 -  associative property of addition.

3. (-14)+81 = 81 + (-14) - commutative property of addition.

4. -72 +0=-72 - additive identity.

5. 13/17•17/13=1 -multiplicative inverse.

<h3>What is a distributive property?</h3>

The distributive Property is one that connote the fact that if a factor is said to be multiplied by the sum or the addition of two terms, it is vital to multiply all of the two numbers by using the factor, and lastly carry out the addition operation.

Hence, The Matchup are:

1. 1/3(24+15)=1/3•24+1/3•15 -  distributive property

2. 101+(29+417) = (101+29) + 417 -  associative property of addition.

3. (-14)+81 = 81 + (-14) - commutative property of addition.

4. -72 +0=-72 - additive identity.

5. 13/17•17/13=1 -multiplicative inverse.
