Step-by-step explanation:
65% of 80= 80×0.65 = 52mins
5/8 of 80= 5/8×80 = 50 mins
<h2>
more mins = 52-50= <em><u>2</u></em><em><u> </u></em><em><u>m</u></em><em><u>o</u></em><em><u>r</u></em><em><u>e</u></em><em><u> </u></em><em><u>m</u></em><em><u>i</u></em><em><u>n</u></em></h2>
Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
Answer:
4
x - ----- = 3
y
Step-by-step explanation:
I'm assuming that you mean:
4
x - ----- + 2 = 5
y
Subtracting 2 from both sides, we get
4
x - ----- = 3
y
adding 4/y to both sides yields:
4
x = 3 + -----
y
