Answer:
34
Step-by-step explanation:
Add them together
5x+10=180
5x+10-10=180-10
5x=170
5x/5=170/5
x=34
So you got
z²+y²=25² and
17²+x²=z²
x²+6²=y²
nice, so we have z² and y² all in terms of x
17²+x²+x²+6²=25²
2x²+289+36=625
2x²=300
x²=150
x=5√6
if we input back to find y and z
17²+x²=z², 287+150=z², √439 =z
x²+6²=y², 150+36=y², √186=y (not simplifying because no graphing calculator, so just eimplify yourself)
A is the only correct answer, unless you meant to put “-5” for letter E. Then A and E would be the correct answers!
To Convert a percentage to a decimal, you divide the percentage number by 100.
6.5% ÷ 100 = .065.
This is the rate you will multiply $14.29 by to get the amount of sales tax you must pay.
The correct answer is (0.065) (14.29) = $0.93
Based on the information provided, none of the above options are correct.
The options provided would make more sense if it were a 6 3/4% tax, and the answer would be B.
C = πd ( in terms of the diameter ), C = 2πr ( in terms of the radius )
