Make the fractions into common denominators
turn 1/2 into 2/4 (common denominator of 4 with 1/4)
then add them
8+7 is 15
1/4+2/4 is 3/4
15+3/4 is 15 3/4

Amanda [17]

Answer:

$P(c(t)) = 20t-120$

Step-by-step explanation:

Given

$P(n) = 2n - 20$

$C(t) = 50 + 10(t - 10)$

Required

Determine $P(C(t))$

The implication of the question is to solve for $P(C(t))$

Given that

$C(t) = 50 + 10(t - 10)$ and $P(n) = 2n - 20$

$P(c(t))$ would be

$P(c(t)) = 2(50 + 10(t - 10)) - 20$

$P(c(t)) = 2(50 + 10t - 100) - 20$

Collect Like Terms

$P(c(t)) = 2(50 - 100+ 10t) - 20$

$P(c(t)) = 2(-50+ 10t) - 20$

Open Bracket

$P(c(t)) = -100+ 20t - 20$

Collect Like Terms

$P(c(t)) = 20t-100 - 20$

$P(c(t)) = 20t-120$

Five devied by three forths

bija089 [108]

Answer:

$6\dfrac{2}{3}$

Step-by-step explanation:

$\dfrac{5}{\dfrac{3}{4}} = \dfrac{5}{1}\times\dfrac{4}{3}=\dfrac{20}{3}=6\dfrac{2}{3}$

When dividing fractions, you just need to remember that all you need to do is get the inverse of the divisor and multipy.

So for the problem

5 = divident

3/4 = divisor

So we get the inverse of 3/4 which is 4/3 and then multiply.

Look above to see the process.
