Answer:
84 and 36
Step-by-step explanation:
The ratio of two numbers is 7:3.
We don't know what the numbers are, but since their ratio is 7:3, we can let the numbers be 7x and 3x. Notice that the ratio between 7x and 3x is 7x/3x = 7/3, so we still have the same ratio, 7:3.
The difference between the numbers is 48.
7x - 3x = 48
4x = 48
x = 12
7x = 7(12) = 84
3x = 3(12) = 36
The numbers are 84 and 36.
Check:
7/3 = 2.333...
84/36 = 2.333...
84 and 36 are int he same 7:3 ratio as 7:3.
84 - 36 = 48
The difference between 84 and 36 is 48 like the problem states.
This shows our answer, 84 and 36, is correct.
Answer:
x= 17
Step-by-step explanation:
5x-7=3x+27
move 3x to other side by doing the oppostie (subtracting 3x)
5x-7-3x=27
2x-7=27
move -7 to other side by adding it (to the other side)
2x= 7+27
2x= 34
divide by 2 (on both sides) to get x by itself
2x/2=34/2
x= 17
