Renee and John have a joint checking account. Their balance at the beginning of September was $6,238.67. During the month they made deposits totaling d dollars, wrote checks totaling $1,459.98, paid a maintenance fee of z dollars, and earned b dollars in interest on the account. Write a simplified algebraic expression that represents the balance at the end of the month

4778.69 + b + d - z

Step-by-step explanation:

Based on the information given above, we would add the deposits made, and the interest earned to the balance at the beginning of September while we would subtract the check written, and the maintenance fee from the balance.

This will algebraically be expressed as:

= 6238.67 + d - 1459.98 - z + b

= 6238.67 - 1459.98 + b + d - z

= 4778.69 + b + d - z

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
