John spent $75 on a shopping trip for new clothes last week. He had expected to spend $100 on clothes,

timofeeve [1]

Answer:

Absolute error = $25

Step-by-step explanation:

Given that:

Amount spent by John on shopping trip = $75

Estimated amount to spent on shopping trip = $100

Absolute error = Approximate value - Exact value

Here,

Approximate value = $100

Exact value = $75

Absolute error = 100 - 75

Absolute error = $25

Percentage = $\frac{Absolute\ error}{Exact\ value}*100$

Percentage = $\frac{25}{75}*100$

Percentage = 33.33%

Hence,

Absolute error = $25

Trinity solved the equation 2(x-3)+7-3x=11.

lukranit [14]

Answer:

$x=-10$

Step-by-step explanation:

$2(x-3)+7-3x=11$

$2\left(x-3\right)+7-3x-7=11-7$

$2\left(x-3\right)-3x=4$

$-x-6=4$

$-x-6+6=4+6$

$-x=10$

$\cfrac{-x}{-1}=\cfrac{10}{-1}$

$x=-10$
