Water runs from a pump at a rate of 0.5 gallons per minute. At this rate, how long would it take to fill a tub with a 150-gallon
lutik1710 [3]

Answer:

300 min or 5 hours

Step-by-step explanation:

so if it pumps 0.5 gallons per minute than in 2 minutes it would pump 1 whole gallon so with that we know 1gallon=2 minutes.

so with that we multipy both sides by 150 which will be 150 galons=300 minutes or 5 hours

I need help! PLEASE HELPP PLEASE HELP!!!
DanielleElmas [232]

Answer:

Part 1: 31x+25=180

part 2: x=5

Step-by-step explanation:

there are 180° on a straight line, which is the base/ bottom line of the traingle (indicated by the arrow on the end).

so, 180-151= 29

29° is the third angle on the traingle.

now, there are 180° in a triangle, therefore to find an equation for x:

29+20x-3+11x-1= 180 (adding up all the angles and making it equal to 180°)

now simplify this equation to get:

31x+25=180 (PART 1)

to find x simply solve the equation:

31x=180-25

31x= 155

x= 155/31

x=5 (PART 2)

5$ is the cost and the cost per ride is 50 cent , if your parents give you 20$ . Write and solve a linear equation to find how m
Lesechka [4]

ANSWER= 30 rides

STEP-BY-STEP EXPLANATION

y=mx+b

m= $0.5 (per ride)

b= $5 (the cost)

x(rides)  and y(parents money)

y= 0.5 x + 5

20= 0.5 x +5

20 - 5 = 0.5 x

15=0.5x

x= \frac{15}{0.5}

x=30 rides
