3(5x+20)=45
3 times 5x=
15x 
3 times 20= 60
15x +60=45
45-60=-15
15x=-15
-15 divided by 15x= 
-1x=
x=1
Hope this helps

Step 1. Divide both sides by 3 

5x+20= \frac{45}{3}

Step 2. Simplify \frac{45}{3} to 15

5x+20=15

Step 3. Subtract 20 from both sides

5x=15-20

Step 4. Simplify 15-20 to -5

5x=-5

Step 5. Divide both sides by 5

x=-1

Done! Your answer is x=-1

Please help. The correct and best answer gets brainiest! 29 points!!
attashe74 [19]

Answer:(15, 100)

Step-by-step explanation:

first find the coordinates of the point above (3, 20)

you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40

so the coordinate would be (6, 40)

now subtract (6, 40) by (3, 20)

6-3= 3

40- 20= 20

you get the first coordnites which is what you add (12,80) to

12 +3= 15

80+ 20= 100

you get the coordinates (15, 100)

karen needs to make a total of 70 deliveries this week. so far she has completed 28 of them. what percentage of her total delive
dolphi86 [110]
To determine the percentage of deliveries Karen has completed, divide the number of deliveries completed by the total deliveries to be made. Then, multiply the quotient by 100%. This is shown below,
                            (28 / 70) x 100% = 40%
Therefore, Karen has completed 40% of her deliveries.
