Mason opens a savings account by making a $165.85 deposit. every week, he deposits another $20.50 in the account.
write an expression that shows the amount of money that will be in the account x weeks after mason opens it.

168.85+20.50x=y

Step-by-step explanation:

165.85 is the initital deposit at 0 weeks, and since every week 20.50 is added, the equation would be 168.85+20.50x=y

To check it, you could check the first week which would be:

168.85+20.50(1)=y

y=189.35

165.85 + 20.5x

Step-by-step explanation:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
