Answer: x=2
Step-by-step explanation:
20+4(3x-5)+2x=28
We move all terms to the left:
20+4(3x-5)+2x-(28)=0
We add all the numbers together, and all the variables
2x+4(3x-5)-8=0
We multiply parentheses
2x+12x-20-8=0
We add all the numbers together, and all the variables
14x-28=0
We move all terms containing x to the left, all other terms to the right
14x=28
x=28/14
x=2
The equation would be 55h+40=c
h-hours
40-Initial value-Price paid at start
c-total cost
so if you plug the numbers in, 55h+40=190
Subtract 40 from both sides, 55h=150
Divide both sides by 55, h=150/55
150/55=<span>2.72727272727
and that rounds to 2.73</span>
1/4 of a ton is equal to 500 pounds
there are 16 ounces in a pound, so multiply the number of pounds by 16 ounces
500*16= 8000 ounces
