Mr. Thompson had a balance of $283.12 in his checking account at the beginning of the month he wrote checks for $23.09 $7.56 $12
ryzh [129]

Account balance is $123.08

Step-by-step explanation:

  • Step 1: Balance in Thompson's account = $283.12. Calculate the total amount of checks Thompson wrote in the month.

Total amount of checks = $23.09 + $7.56 + $125.11 + $4.28

                                        = $160.04

  • Step 2: Calculate his balance.

Account balance = $283.12 - $160.04

                            = $123.08

Combing like terms -4(7 + 3a) -6a(4a - 5)
Ludmilka [50]

Answer:

-24a² - 42a - 28

Simplified form =  12a² + 21a + 14

Step-by-step explanation:

-4(7 + 3a) - 6a(4a - 5) (distribute -4)

-28 - 12a -6a(4a - 5) (distribute -6a)

-28 - 12a -24a² - 30a (collect like terms)

-24a² - 42a - 28

We can simplify

-24a² - 42a - 28 (divide -2)

12a² + 21a + 14

Hope this helps ya! Keep smiling!

Compare:<br><br> X and X decreased by 50% and then increased by 50% of the result
kaheart [24]

Step-by-step explanation:

100% = X

50% = 100%/2 = X/2

X decreased by 50 means X - 50% = X - X/2 = X/2

now,

100% = X/2

50% = 100%/2 = X/2 / 2 = X/(2×2) = X/4

increasing the previous result by 50% means

X/2 + 50% = X/2 + X/4 = 2X/4 + X/4 = 3X/4

so, comparing this to the original X (= 4X/4), we are X/4 short.
