13^12 + 11^12 + 8^12 = 384 It will cost 384 dollars for all 12 uniforms
Answer:
k = 3
Step-by-step explanation:
5(ky-6)=15y-30
Factor out a 5 from the right side
5(ky-6)=5(3y-6)
Divide each side by 5
ky -6 = 3y -6
Add 6 to each side
ky = 3y
divide by y
k = 3
Answer:
91
Step-by-step explanation:
Mean is calculated as
mean = 
let x be his test score of his last test , then
= 85 ( multiply both sides by 7 )
504 + x = 595 ( subtract 504 from both sides )
x = 91
V1 + V2
V1 = 1*2*1 = 2
V2 = 5*2*2 = 20
V1 + V2
2+20
22
Answer:
<em>The expression is equal to 22</em>
Step-by-step explanation:
<u>Expression Evaluation</u>
We are given the expression
10 + 2p - 3r
And it's required to evaluate it when p=3 and r=2. This means we have to replace the letter for the value assigned to them, as follows:
10 + 2*3 - 3*(-2) = 10 + 6 - (-6)
= 10 + 6 + 6
= 22
The expression is equal to 22
