Write a real-world situation that can be modeled by the inequality 20x > 30 + 15x.

20x > 30 + 15x.

John and Jack were making steel bars. John started earlier, and had already completed 30 steel bars by the time Jack clocked in for work. To make up the time, Jack created 5 more bars per hour then usual (usual being 15 bars an hour). How much hours are needed before Jack could surpass John?

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
