Answer:

1) A = 80

2) A = 30

Step-by-step explanation:

1) x+50 + 80 + x + 70 = 180

2x+120 = 180

2x = 60

x=30

A = (30) + 50

A = 80

2) x+40 + x+90 + (180-110) = 180

x+40 + x+90 + 70 = 180

2x + 200 = 180

2x = -20

x = -10

A = (-10) + 40

A = 30

Samuel buys office supplies for his home business. The office supplies cost $175.79 before taxes. The sales tax rate is 8.25%. What is the amount of sales tax Samuel will pay?

Answers

Answer:

175.79* .0825 = 14.50 + 175.79 =  190.29 $190.25

Step-by-step explanation:

The amount of sales tax Samuel will pay is $14.50

Sales tax rate

Given the following information

cost of office supplies = $175.79 sales tax rate = 8.25%

Get the amount of sales tax:

Amount of sales tax = 8.25% of $175.79

Amount of sales tax = 0.0825 * 175.79

Amount of sales tax = $14.50

Hence the amount of sales tax Samuel will pay is $14.50

Equation:

Solution: x=

Answers

Answer:

As an equation: 15 × x = -75

Solved: x = -5

Step-by-step explanation:

15*x = -75

[tex]\frac{15*x}{15}[/tex] = [tex]-\frac{75}{15}[/tex], Divide by 15 on both sides to solve for x

x=[tex]-\frac{75}{15}[/tex], The 15 in the numerator cancels out with the denominator

x= -5, because 75/15=5

Equation: (-5)(15) = -75

Solution : (x)(15) or (written as, x times 15 )= -75
For x= -5 ( substitute x into -5)
(-5)(15) or written as, negative 5 times 15= -75

What is Unitary Method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

For cotton:

5.54 ÷ 3/4

=7.39<8

For flannel:

2.62 ÷ 3/4

=3.49<8

For fleece:

4.27 ÷ 3/4

=5.69 < 8

For terry cloth:

=6.52 ÷ 3/4

= 8.69>8

So, cost less than $8 per yard cotton, flannel and fleece.

For a certain race, 4 teams were allowed to enter 3 members each. A team earned 9 – n points whenever one of its members finished in nth place, where 1 ≤ n ≤ 8. There were no ties, disqualifications, or withdrawals. If no team earned more than 10 points, what is the least possible score a team could have earned?

A) 0

B) 1

C) 2

D) 3

E) 4

Answers

Answer:

D. 3 Points

Step-by-step explanation:

Given

[tex]Members = 3[/tex]

[tex]Point = 9 - n[/tex]

[tex]1 \leq\ n \leq 8[/tex]

Required

Determine the least possible score

The least point a member of a team can get is when n = 8.

i.e.

[tex]Point = 9 - n[/tex]

[tex]Point = 9- 8[/tex]

[tex]Point = 1[/tex]

To get the least score, each of the 3 members must have 1 point each.

So:

[tex]Total = 3 * 1[/tex]

[tex]Total = 3[/tex]
