Which linear equations have one solution? Check all that apply. 5x – 1 = 3(x + 11)
4(x – 2) + 4x = 8(x – 9)
4(x – 6) + 4 = 2(x – 3)
2(x – 4) = 5(x – 3) + 3
2(x – 1) + 3x = 5(x – 2) + 3

What is the missing step in this proof ?

Acar started driving from city a to city b, distance between which is 620 miles, at a rate of 60 mph. two hours later a truck left city b and started moving towards city a at a rate of 40 mph. what distance from city a is the point where the truck and the car will meet?

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
