Answer:
x=2
Step-by-step explanation:
9x+9=25+x
9x-x=25-9
8x=16
x=2
We have to divide 9/10 by 3/12.
if we divide by a fraction, we can instead multiply by it's inverse:

so now we count:

so we can cut exactly 3 pieces!
We take each number as x = 2x 3x 4x
(2x)³+(3x)³+(4x)³=33957
8x³+27x³+64x³=33957
99x³=33957
x³=33957÷99
=∛343
x=7
2x=2×7=14
3x=3×7=21
4x=4×7=28
=the three numbers are 14,21,28
Find one ounce $3.92/8=$0.49
$0.49 per ounce
X hour and 7 dollars per hour
x = hour
7(x) is your function
thank you for Anlian for pointing it out.. there is 4 hours
so x = 4
plug in 4 in x. 7(4)
7 x 4 = 28
28 is your answer
hope this helps
