Melissa, Dan, and Henry have $87 in their wallets. Dan has 3 times what Henry has. Melissa has $8 less than Henry. How much does

puteri [66]

Answer:

Henry has $19, Dan has $57, and Melissa has $11

Step-by-step explanation:

Let x represent how much money Henry has

Since Dan has 3 times what Henry has, his amount is 3x

Since Melissa has $8 less than Henry, her amount is x - 8

Create an equation that sets these 3 values equal to 87, then solve for x

(x) + (3x) + (x - 8) = 87

5x - 8 = 87

5x = 95

x = 19

So, Henry has $19

Find how much Dan has by multiplying 19 by 3

19(3)

= 57

Find how much Melissa has by subtracting 8 from 19

19 - 8

= 11

So, Henry has $19, Dan has $57, and Melissa has $11

What is the remainder of (3x^4+2x^3-x^2+2x-14)/ (x+2)

Allisa [31]

Hi,

I assume the forward slash meant it as a fraction VS it being a division symbol. To answer your question, the remainder is 10.

Hope this helps.

I need the answer- it's easy!

kaheart [24]

1) You add 72+89 which you get 161 and you divide by two and you get 80.5
2) you do the same thing 72+89+90=251
And you divide by three and you get ≈83.66

Mr.Ramirez had $600. He saved 3/5 and spent 3/8 of the remainder

Alex73 [517]

Answer:

$450

Step-by-step explanation:

Given function:

$600,3/5,3/8

To solve:

$600-3/5-3/8+3/5

Subtract the two terms:

$600=\frac{30}{5}$
$600$ · $\frac{3}{5}=360$

Subtract the first value by 360:

$600-360=240$

Find 3/8 of 240 and then subtract it:

$240$ · $\frac{3}{8}=90$

Combine the terms:

$360+90=450$

Therefore, Mr.Raminrez now have a total of $450..
