2) 15 was subtracted from a number and that difference was then divided by 0.7. After which, that quotient was multiplied by 3. The resulting product was -3. What was the number?
1 answer:
Answer:
A number (x) is 14.3
Step-by-step explanation:
You can write the problems like this and solve starting with z to x
x - 15 = y (15 was subtracted from a number)LAST HERE
x = 15 + -0.7
x = 14.3
y / 0.7 = z (and that difference was then divided by 0.7.)THEN HERE
y = -1 x 0.7
y = -0.7
3z = -3(After which, that quotient was multiplied by 3. The resulting product was -3.) START HERE
z = -3 / 3
z = -1
CHECK
14.3 - 15 = -0.7 -0.7 / 0.7 = -1 3 x -1 = -3
