Andrea is 4 inches taller than Pierre. If their combined heights total 152 inches, how tall is Andrea and Pierre? Write a let statement(s) and set up the equation. then solve.

Okay, so to find this out, we need to place aside 4 inches for Andrea, but we will not add them to her total yet:

Andrea: 0 in

Pierre:   0 in

Total:  (152 - 4 =) 148 in

[set aside: 4 in]

Now that the 4inches are set aside, we just need to divide the Total Height in half, because there are 2 people who are sharing this amount:

148 ÷ 2 = 74

Now that we have the answer for this, we now have Pierre's height:

Andrea: 0

Pierre:  74

Total:    74

[set aside: 4 + 74]

And we then take the Set Aside amount, and make it Andrea's height:

Andrea: 78

Pierre:   74

Total:    152

[set aside: 0]

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
