Ratio question: Paul and Luke share some money in the ratio 4:7. Paul gets £12 less than Luke. How much did they have in total?

Oksanka [162]

P/L=4/7 and P=L-12 so

(L-12)/L=4/7 multiply both sides by 7

(7L-84)/L=4 multiply both sides by L

7L-84=4L subtract 4L from both sides

3L-84=0 add 84 to both sides

3L=84 divide both sides by 3

L=28, and since P=L-12

P=16

So they had 28+16 = £44 in total.

A. 44.99 + 0.75(29.99)x = 44.99 + 22.49x

B. 1.08(44.99 + 22.49x )

C. 1.08(44.99 + 22.49(4)) = 1.08 (44.99 + 89.96) = 1.08(134.95) = 145.75

4(4m-3)-m(m-5)=-52 need all the steps

nadezda [96]

$\huge\mathcal {♨Answer♥}$

$\large\texttt{Simplifying: }$

4(4m -3) + -1m(m + -5) = -52

$\large\texttt{Reorder the terms: }$

4(-3 + 4m) + -1(m + -5) = -52

(-3 * 4 + 4m * 4) + -1(m + -5) = -52

(-12 + 16m) + -1(m + -5) = -52

$\large\texttt{Reorder the terms: }$

-12 + 16m + -1(-5 + m) = -52

-12 + 16m + (-5 * -1 + m * -1) = -52

-12 + 16m + (5 + -1m) = -52

$\large\texttt{Reorder the terms: }$

-12 + 5 + 16m + -1m = -52

$\large\texttt{Combine like terms: }$

-12 + 5 = -7

-7 + 16m + -1m = -52

$\large\texttt{Combine like terms: }$

16m + -1m = 15m

-7 + 15m = -52

$\large\texttt{Solving: }$

-7 + 15m = -52

-7 + 7 + 15m = -52 + 7

$\large\texttt{Combine like terms: }$

-7 + 7 = 0

0 + 15m = -52 + 7

15m = -52 + 7

$\large\texttt{Combine like terms: }$

-52 + 7 = -45

15m = -45

$\large\texttt{Divide each side by '15'. }$

15m ÷ 15 = -45 ÷ 15

m = -3

$\large\texttt{Simplifying: }$

m = -3

A race is 3 miles long. There are water stations every 3/4 mile along the route. How many water stations are along the route?

Vilka [71]

There will be 4 water stations.

Why?

3/4 = .75 as a decimal

Personally, I believe that it’s easier to use decimals, I can explain the way in fractions in the comments if you’d like, just ask.

Anyway, .75 • 4= 3

or 3 / .75 = 4 (division is easier with bigger numbers)

so, there will be 4 water stations, given that the one race is 3 miles long.

If this explanation seems unclear, I’d be happy to explain. Feel free to ask in the comments!! I’m happy to help.

Hope this helps!

(If you find this answer helpful, please consider marking me brainliest, Thanks!)
