Answer:
7x-20=2x-3(3x+2)
We move all terms to the left:
7x-20-(2x-3(3x+2))=0
We calculate terms in parentheses: -(2x-3(3x+2)), so:
2x-3(3x+2)
We multiply parentheses
2x-9x-6
We add all the numbers together, and all the variables
-7x-6
Back to the equation:
-(-7x-6)
We get rid of parentheses
7x+7x+6-20=0
We add all the numbers together, and all the variables
14x-14=0
We move all terms containing x to the left, all other terms to the right
14x=14
x=14/14
x=1
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
2x-3+4x=21
Isolate the variable by dividing each side by the factors that don't contain the variable
Hi there,
2400 + 1632 = 4032
3 * 192 = 576
4032 - 576 =>
3532 - 76 =>
3532 + 24 - 76 - 24
3556 - 100
3456
3456 / 576 => 6
Therefore, 6 hours of sprayer work
Hope this helps!
Sincerely,

Gas mileage = 30.5 mi/gal
Volume of gas = 1.5 l
Note that 1 liter = 0.264172 gallons
Therefore
1.5 l = (1.5 l)*(0.264172 gal/l) = 0.3963 gal
Distance traveled is (Gas mileage, mi/gal)*(Gal of gas)
= (30.5)(0.3963) = 12.087 mi
Answer: 12 mi (nearest integer)
