Answer:

(4,9)

Step-by-step explanation:

To solve this, you can use substitution or elimination. In this case I would use substitution. To do this, you have to isolate a variable. x is already isolated so we can skip this step. plug x into 5x-7y=-43. This will make the equation 5(2y-14)-7y=-43. Simplify this to get 10y-70-7y=-43. Simplify this to get 3y-70=-43. Add 70 in both sides to isolate y. This will make the equation 3y=27. Divide both sides by 3 to make y equal to 1. This will make the equation y=9. Now you know that y=9. Plug 9 into any equation. x=2(9)-14. Simplify this to get x=18-14. x=4. Now put the numbers as an ordered pair which is (x,y). We know that x=4 and y=9 so it is (4,9).

plz help Pru, Piper, and Phoebe share spices in the ratio 5:3:4. If Pru has 24 more spices than Piper, how many spices does Phoe
disa [49]

Answer:


Step-by-step explanation:

Pru, Piper, Phoebe ratio 5:3:4vadded = 12

What this means is Pru has 5/12 of the total amount, Piper has 3/12 of the total amount, and Phoebe has 4/12 of the total amount of spices.


pru = piper + 24

5/12x = 3/12x + 24

5/12x - 3/12x = 24

2/12x = 24

x = 24 / (1/6)

x = 24 * 6

x = 144 spices in total


Pru has : 5/12(144) = 720/12 = 60 spices

Piper has : 3/12(144) = 432/12 = 36 spices

Phoebe has : 4/12(144) = 576/12 = 48 spices


I hope this can help.

Lacey, because you have to do the opposite when you want to get rid of a number. She subtracted 20 because it was originally positive 20. Chris messed up and did not do the opposite, subtraction, and instead he added 20
