Mashutka [201]

Answer:

$2,677.72

Step-by-step explanation:

L = 3C

P

4P + 3L = 1,580.62

2L + 5C = 1,340.90

4P + 5L + 3C = ?

2L + 5C = 1,340.90

6C + 5C = 1,340.90

11C = 1,340.90

C = 121.90

121.90 * 3 = 365.70

L = 365.70

4P + 3L = 1,580.62

365.70 * 3 = 1,097.10

4P = 483.52

P = 120.88

C = 121.90

L = 365.70

P = 120.88

4P + 5L + 3C = ?

4(120.88) + 5(365.70) + 3(121.90) = 2,677.72

A circle with a circumference of 51 inches to find the area
Kaylis [27]

\textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=51 \end{cases}\implies 51=2\pi r\implies \boxed{\cfrac{51}{2\pi }=r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2\qquad \implies A=\pi \left( \cfrac{51}{2\pi } \right)^2\implies A=\cfrac{51^2}{2^2\pi }\implies A\approx 206.98

LaDonna is running for city council. She needs to get four fifths 4 5 of her votes from senior citizens and 40 comma 00040,000 v
Colt1911 [192]
She needs in total 40,000 votes, and from those 40,000, 4/5 need to be from senior citizens, now, 5/5 is a "whole", so 5/5 - 4/5 that leaves only 1/5.

therefore, of those 40,000 votes, 1/5 can be of non-senior citizens, how much is 1/5 of 40,000?  well, is just their product,

\bf \cfrac{1}{5}\cdot 40000\implies \cfrac{40000}{5}\implies 8000

Which expressions are equivalent to <br> x+x+x+2?
Alexxandr [17]

Answer:

3x + 2

Step-by-step explanation:

x = 1x but leaving the x alone equals the exact thing.

If there are x + x + x, this means 3x since it is also

1x + 1x + 1x.

This is another expression for 3x + 2.
