Answer:

Step-by-step explanation:

If Quan had 15 and Kaden had 3 times as much, then Kaden had 15(3) = 45. If he spent 10 then he had 35 left. The amount of money Quan had after his mom gave him some was 4/5 the amount of Kaden's 35 (let x = the amount of money Quan has after his mom gives him some):

x=\frac{4}{5}(35)  35 divides by the 5 in the denominator 7 times, and 7 times 4 is 28. That's how you get your 28 in part a.

For part b., he started with 15 and ended with 28, so his mom gave him 28-15=13. That's how you get the 13.

Mark knows that his yard is 214 times as long as it is wide. Which equation shows the length, in feet, of the fence that goes al
irakobra [83]

Answer:

Length in feet is equal to \frac{2P}{6.5}, where P is the perimeter

Step-by-step explanation:

Let the width (W) of the yard be "X"

W = w

Then the length(L) of the yard will be

2\frac{1}{4} * w

L = \frac{9}{4} *w

The perimeter of the yard will be equal to the sum of twice the length and width of the yard

Thus,

P = 2 W + 2L\\

Substituting the given values in above equation, we get -

P = 2 w + 2 (\frac{9}{4})w\\P = 2w + 4.5 w\\P = 6.5w

Thus, width in terms of perimeter is equal to

w = \frac{P}{6.5}

Length in feet is equal to \frac{2P}{6.5}
