How many solutions does this equation have? -4 - 20s = -2(10s + 2) no solution one solution infinitely many solutions how do I go about solving this problem?

infinitely many

Step-by-step explanation:

divide two from both sides to get -2-10s=10s+2

this is the same equation but u can go even farther and add or subtract 2 from both sides to get -10s=10s

then add or subtract 10 from both sides to get s=s

if this make any sense jus comment and i will explain it another way

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.
