Arthur earned $136 in three weeks. he goes back to school in one more week. he needs at least $189 to buy the new coat that he wants for school. how much must arthur earn in the next week?write an inequality to represent this siutation.

Answers

Answer: $53

Step-by-step explanation:

Given: Earning of Arthur in three weeks = $136

Let x be the money he earn in one more week.

If he needs at least $189 to buy the new coat that he wants for school.

Then it gives the inequality $136+x\geq 189$

Subtract 136 from both sides of the inequality, we get

$x\geq 189-136\n\Rightarrow\ x\geq 53$

Hence, Arthur must earn $ 53 in the next week.

An inequality:
136 + x ≥ 189
x ≥ 189 - 136
x ≥ 53
Answer:
He must earn at least $53.

Which fraction expresses -30/54 in lowest terms? A. - 10/27
B. - 10/18
C. - 15/27
D. - 5/9

Answers

-30/54 in simplest form:

First, we can start out by finding the greatest common factor (GCF) of the numerator (30) and the denominator (54). To do so, we will list the factors of each number, find the common ones and then the greatest.

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54

Look through both sets of factors. Which are the common factors? 1, 2, 3, and 6 are the common factors of 30 and 54. Now, we have the find the greatest common factor. Basically, which number has greater value out of 1, 2, 3, and 6? The GCF is 6.

Second, our last step is to divide the numerator (30) and denominator (54) by our recently found GCF which was 6. This will create a new fraction which is in simplest form.

$30 / 6 = 5 \n 54 / 6 = 9$

Let's collect our new numerator and denominator and rewrite our brand new fraction in its simplest form.
$-(5)/(9)$

Answer in fraction form: $\fbox {-5/9}$
Answer in decimal form: $\fbox {-0.5556}$

Sales tax is added to the price of items sold on eBay. If someone in Arizona buys an item online for $22.50 and the state sales tax rate is 6.6%, what is the final selling price

Answers

Price of the online item bought by someone in Arizona = $22.50
Percentage of state sales tax that needs to be paid = 6.6%
Then
Amount of sales tax that needs to be paid = (6.6/100) * 22.50
= 148.5/100 dollars
= 1.48 dollars
So
The final price that needs
to be paid for the online item = (22.50 + 1.48) dollars
= 23.98 dollars
