How many solutions does the following equation have -14(z-5)=-14z+70

The given equation has NO solutions    

Step-by-step explanation:

Given equation as :

- 14 (z - 5) = - 14 z + 70

Or, - 14 z + 70 = - 14 z + 70

Since the coefficient of variable z is same on both side i.e ( - 14 ) , So , the Given equation has NO - solution .

Hence the given equation has NO solutions    Answer

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
