Answer:
0.12 x (x + 3000) = 4200
equation for her salary last year : last year's salary = (4200 / 0.12) - 3000
$32,000
Step-by-step explanation:
Let x = last year's salary
this year's salary = 3000 + x
this equation can be used to determine how much she saved this year = 0.12 x (x + 3000) = 4200
to find last year's salary, make x the subject of the formula
4200 / 0.12 - 3000 = x
x = $32,000

Jenny = 8x
Clark's = x
8x + x = 36
9x = 36
9x/9 = 36/9
x = 4
Jenny = 8 x 4 = 32
So Clark's ball went the distant of 4 and Jenny's ball went 32
Answer:
x=136.75
Step-by-step explanation:
Let's solve your equation step-by-step.
x+0.17x=160
Step 1: Simplify both sides of the equation.
x+0.17x=160
(x+0.17x)=160(Combine Like Terms)
1.17x=160
1.17x=160
Step 2: Divide both sides by 1.17
Answer:
