Easier than it looks, all you have to do is first subtract 13 from 299. You should get 286. Then, you just divide this number by two to get 143. Finally, since it asks for ZENA'S average, you add the 13 back to 143 to get the final answer of the average number of pins Zena took down, which is 156!

kkurt [141]

Based on the deposits and written checks, Mr. Williams' account balance at the end of the month is <u>$3,606</u>.

<h3>What is the account balance?</h3>

The account balance represents the net amount remaining in the account after subtracting the checks from the deposits.

Other factors are taken into account for determining the account balance, including direct credits and debits like bank transfers and charges for bank services.

Thus, the account balance can be utilized by Mr. Williams for his banking transactions in March.

<h3>Data and Calculations:</h3>

Total Deposits = $5,255 ($949 + $1419 + $1598 + $1289)

Total checks = $1,649 ($84 + $167 + $352 + $384 + $662)

Account balanced = $3,606 ($5,255 - $1,649)

Thus, based on the deposits and written checks, Mr. Williams' account balance at the end of the month is <u>$3,606</u>.

Let m = 6x + 5.<br><br> Which equation is equivalent to (6x + 5)2 – 10 = -18x – 15 in terms of m?
sweet-ann [11.9K]

Answer:

m² + 3m - 10 = 0

Step-by-step explanation:

Given

(6x + 5)² - 10 = - 18x - 15 ← factor out - 3 from each term

(6x + 5)² - 10 = - 3(6x + 5)

Now let m = 6x + 5 in the equation, that is

m² - 10 = - 3m ( add 3m to both sides )

m² + 3m - 10 = 0
