Answer:
the answer is 9
Step-by-step explanation:
why it 9 Add '2.7' to each side of the equation.
-2.7 + 2.7 + 0.3x = 9 + 2.7
Combine like terms: -2.7 + 2.7 = 0.0
0.0 + 0.3x = 9 + 2.7
0.3x = 9 + 2.7
Combine like terms: 9 + 2.7 = 11.7
0.3x = 11.7
Divide each side by '0.3'.
x = 39
Simplifying
x = 39
Answer:
30% of 30 is 9, so the sale price is $21.00
Step-by-step explanation:
use a calculator and find 30% of 30$, then subtract the value from the calculator, boom, done.
Answer:
27.7 degrees
Step-by-step explanation:
We can use the inverse sine to find the angle x as we are given the opposite sided length and the hypotenuse
x = sin-1(13/28)
x = 27.66
x = 27.7 (round to tenths)
subtract the 26 1/2 from 76 and then divide by 2
76-26 1/2 = 49 1/2 / 2 = 24 3/4
