Answer:
x = -3
Step-by-step explanation:
3x - 21 = 2x - 24
3x = 2x - 3
x = -3
Answer:
x = 45
Step-by-step explanation:
First, we need to use the distributive property on both sides of the equation. We multiply the number outside of the parentheses by every term inside the parentheses.
3(x - 7) = 2(x - 12)
3x - 21 = 2x - 24
From here, we solve for x.
3x - 21 = 2x - 24
x - 21 = 24 (Subtract 2x from both sides)
x = 45 (Add 21 to both sides)

A long-distance delivery truck averages 8 miles per gallon when the truck is full. The
miles per gallon improves by 20% when the truck is empty. If the truck travels 160 miles
full to deliver its goods, and then travels back 160 miles empty, approximately how many
gallons will the truck use in all?
The gas used by truck is 36.66 mpg.
What is linear equation?When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.
One-variable linear equations and two-variable linear equations exist.
Given
A long-distance delivery truck averages 8 miles per gallon when the truck is full.
The miles per gallon improve by 20% when the truck is empty.
The distance delivery truck averages 8 miles per gallon when full, and the amount of gasoline used (g) is expressed in terms of the number of miles driven ([tex]m_{f}[/tex]).
When the truck is full, the amount of gasoline is shown as,
[tex]m_{f}[/tex] = d/8
given distance is 160 miles
[tex]m_{f}[/tex] = 160/8 = 20 mpg
Then,
The miles per gallon improve by 20% when the truck is empty.
The number of miles driven when empty is represented as,
[tex]m_{e}[/tex] = d/(8 + 1.6)
[tex]m_{e}[/tex] = d/9.6
[tex]m_{e}[/tex] = 160/9.6
[tex]m_{e}[/tex] = 16.66 mpg
total gasoline required = [tex]m_{e}[/tex] + [tex]m_{f}[/tex] = 20 + 16.66 = 36.66 mpg
Hence the total gas used is 36.66 mpg.

37=-3+5(x+6), Please provide explanation.
Answer:
x=2
Step-by-step explanation:
youd distribute the 5 first so the equation is now
37=-3+5x+30
then group the common terms (-3 and 30 in this case)
37=5x+27
now subtract 27 from both sides to start to isolate 5x
10=5x
divide by 5 to find x

Step-by-step explanation:
In a rhombus, all sides are congruent; they have the same lengths (like a square). This means that if this parallelogram was a rhombus, 14 - x and 2x + 8 will have to be equal.
14 - x = 2x + 8
Subtract 2x from both sides
14 - 3x = 8
Subtract 14 from both sides
-3x = -6
Divide both sides by -3
x = 2

Step-by-step explanation:
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
