The sum of four consecutive intergers is 8 What are the intergers
Semmy [17]
Consecutive integers are 1 apart
so the 4 are
x, x+1,x+2,x+3

they add to 8

x+x+1+x+2+x+3=8
4x+6=8
minus 6 both sides
4x=2
divide both sides by 4
x=1/2
false, 1/2 is not an integer

if it was adding to 18, then the integers would be 3,4,5,6
but we can't find consecutive integers that add to 8

On anne's bicycle, the ratio of pedal turns to rear-wheel turns in second gear is 4 to 7. if her rear wheel turns 875 times per
quester [9]
Let the number of times she turns the pedal in one mile be x.

Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then

\frac{4}{7} = \frac{x}{875}  \\  \\ \Rightarrow 7x=4(875)=3,500 \\  \\ \Rightarrow x= \frac{3,500}{7} =\bold{500}

Therefore, she turns the pedal 500 times in one mile.
