Answer:

r = 11

Step-by-step explanation:

Solve for r:

3 r - 24 = 9

Add 24 to both sides:

3 r + (24 - 24) = 24 + 9

24 - 24 = 0:

3 r = 9 + 24

9 + 24 = 33:

3 r = 33

Divide both sides of 3 r = 33 by 3:

(3 r)/3 = 33/3

3/3 = 1:

r = 33/3

The gcd of 33 and 3 is 3, so 33/3 = (3×11)/(3×1) = 3/3×11 = 11:

John, and bill shared $900 in the ratio 7:3 respectively. how much money did each person get?

S_A_V [24]

John get money $630 and bill get money $270.

Given that John and bill shared $900 in the ratio 7:3 respectively.

The ratio is defined as the comparison of two quantities of equal units, indicating the quantity of one quantity contained in the other quantity.

The total ratio is 7+3=10

For john:

John has money seven out of 10 for the $900, we get

J=900×(7/10)

J=90×7

J=630

For bill:

Bill is three out of ten for $900, we get

B=900×(3/10)

B=90×3

B=270

Hence, john get money $630 and bill get $270 when they both shared $900 in the ratio 7:3 respectively.
