Answer:
The equation is Linear
Step-by-step explanation:
Answer:
i can't solve it because it's not complete
you need something 2^2 (right here) -^1=8^x-1
Step-by-step explanation:
For this case we can make the following rule of three:
21 ------> 70%
x --------> 100%
Clearing x we have:
x = (100/70) * (21)
Rewriting we have:
x = (10/7) * (21)
x = 30
Thus,
21 is 70% of 30
Answer:
21 is 70% of 30
Answer:
x =53.85
Step-by-step explanation:
Let x be the original price
If the price is 22% of, you will pay 100% -22% = 78%
x * 78% = 42
Change to decimal form.
78x = 42
Divide each side by .78.
78x/.78 = 42/.78
Rounding to the nearest cent
x =53.85
Answer:
35%
total number of 11th graders = 32+18 = 50
calculating percentage:
18÷50×100
= 36%
