you have to switch the numbers for it to be a proper division problem
Hope this helps!

And the slope of a line perpendicular is 3/4
Answer:
George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus
Step-by-step explanation:
<u><em>The question is</em></u>
Find how many kilometers they traveled by bike
Let
x ----> kilometers traveled by bike
y ----> kilometers traveled by bus
we know that
They traveled 300 kilometers in total
so
----> equation A
They biked 70 kilometers more than they were bus
so
----> equation B
substitute equation B in equation A

solve for y

<em>Find the value of x</em>

therefore
George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus
M + w + c = 2838
w = 3c + 5
m = 4w - 3......4(3c + 5)- 3 = 12c + 20 - 3 = 12c + 17
(12c + 17) + (3c + 5) + c = 2838 .....combine like terms
16c + 22 = 2838
16c = 2838 - 22
16c = 2816
c = 2816/16
c = 176 <==== children
w = 3c + 5
w = 3(176) + 5
w = 533 <=== women
m = 12c + 17
m = 12(176) + 17
m = 2129 <=== men
