Answer:
B i think let me solve
Step-by-step explanation:
X= 180
now you have to multiply all them with 180
5(180)= 900
2(180)= 360
3:4
6:8
9:12
if u either multiply or divide a number from one side, u must do the same calculation to the other side. hope that helps :)
58 if you add the two numbers then subtract the answer from 180 that’s the answer
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
