Answer:
The length is 15 yards
Step-by-step explanation:
Given
Represent the width with W and length with L: So
Required
Determine the length of the rectangle:
Area is calculated as thus:
Substitute 3W - 12 for L and 135 for Area
Reorder:
Divide through by 3
Expand:
or 
or 
But width can't be negative
So:
Recall that:
<em>Hence, the length 15 yards</em>
56/1 x 11/8 here is the equations now just multiply them
0.4 gallons * 4.2 hours = 1.68 gallons
Gabriel uses 1.68 gallons in 4.2 hours.
Answer:
1. multiplication property of equality
2. division property of equality
Step-by-step explanation:
1. multplied by -3/2
2. divided by -2/3
Answer:
C. Divide both sides of the equation by -2.
Step-by-step explanation:
The goal of the equation is to isolate x. In order to do that we have to remove the '-2' by doing the inverse operation. That is the opposite operation, for example addition and subtraction, multiplication and division.
Since x is being multiplied by -2, we do the inverse which is division.
