Answer:
y-1=0
Step-by-step explanation:
To rewrite the equation 5x - 8y + 3 = 5x - 7y + 2, combine like terms across the equal sign using inverse operations.
5x - 8y + 3 = 5x - 7y + 2
5x - 5x - 8y + 3 = 5x - 5x -7y + 2
-8y + 3 = -7y + 2
-y +3 = 2
-y = -1
y- 1 = 0
Leroi’s account
$100
After first deposit = $100+$10=$110
After second deposit= $110 + $10 = $120
Sylvia’s account
$100
10% of $100 is $10
After first deposit = $100+ $10 = $110
10% of $110 = $11
After second deposit = $110 + $11 = $121
Therefore after their first deposit, both will have the same value in their accounts.
But after the second deposit, Sylvia will have 1$ more in her account than Leroi.

Answer:
x = 9, y = 27
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
12(x - 1) = 96 ( divide both sides by 12 )
x - 1 = 8 ( add 1 to both sides )
x = 9
Also
= ( cross- multiply )
12(y + 1) = 336 ( divide both sides by 12 )
y + 1 = 28 ( subtract 1 from both sides )
y = 27
Answer:
-315
Step-by-step explanation:
Plug in 5 as a and -7 as b into the term:
9ab
9(5)(-7)
Multiply:
= -315
So, the answer is -315.
