GalinKa [24]

Answer: $13.80

Step-by-step explanation:

Mary ann spent $26.85 total on two new toys but had a coupon for $1.00 off her total purchase. Therefore, we subtract $1.00 from $26.85. This will be:

= $26.85 - $1.00

= $25.85

Shw then spend $1.75 on sales tax. Total coat will now be:

= $25.85 + $1.75

= $27.60

Since each toy coat same amount, therefore each toy will cost:

= $27.60 / 2

= $13.80

Complete the equation to represent finding x, the greater integer.<br><br> x(x – ) = 143
mart [117]

Answer:

x would equal -11 or 13

Step-by-step Explanation:

x(x - 2) - 143 = 0

x^2 - 2x - 143 = 0

-2x + x^2 = 143

-143 + (-2x) + x^2 = 0

(x - 13)(x + 11)

x - 13 = 0

Add 13 to both sides

x = 13

x + 11 = 0

Subtract 11 from both sides

x = -11
