Answer:

x = 8

Step-by-step explanation:

We can use PEMDAS to solve algebraic equations:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

First, we have parentheses in this equation, so distribute

3(11x) + 3(5) = 279

Next, because there are no exponents, multiply

33x + 15 = 279

To isolate x, subtract 15 from both sides

33x + 15 - 15 = 279 - 15

33x = 264

Then divide both sides by 33

x = 8

An arcade charges for admission and tokens. Admission and 3 sets of tokens costs $50. Admission and 5 sets of tokens costs $80. What is the price of admission (initial value)?

A) $15

B) $5

C) $8

D) $3

_____________________________________

Answer: B) $5

1 Token Costs: $15.00

Admission Costs: $5.00

_______________________________

$15.00 × 5 = $75.00

$75.00 + $5.00 = $80.00

_______________________________

$13.00 × 3 = $45.00

$45.00 + $5.00 = $50.00

James estimated the total cost of groceries to be $50. The actual cost of the groceries is $65. What is the percent error? Round

Yuki888 [10]

The percentage error is 23%

Explanation:

The estimated total cost of the groceries = $50

The actual cost of the groceries = $65

To find the error value, we need to subtract the value of actual cost and total cost of the groceries.

Thus,

error value = actual cost - total cost

error value $= 65-50=15$

Hence, error value = $15

The formula to determine the percent error is given by

$Percent error $=\left(\frac{\text { error value}}{\text {actual value}}\right) \times 100$$

Substituting the values in the formula, we get,

$\begin{aligned} \text { Percent error } &=\left(\frac{15}{65}\right) \times 100 \\ &=0.231 \times 100 \\ &=23.1 \end{aligned}$

Rounding off the value, we have, 23%

Thus, the percentage error is 23%
