Which of the following steps would you perform to the system of equations below so that the equations have equal x coefficients? 4x+2y=4 12x+y=22 A. Multiply both sides of the top equation by 3 B. Divide both sides of the top equation by 3 C. Divide both sides of the bottom equation by 2 D. Multiply both sides of the bottom equation by 3​

Answers

Answer 1
Answer: A.

Explanation:
By multiplying the top equation by 3, you now have

12x + 6y = 12
12x + y = 22

To completely solve the equation, you multiply the whole bottom equation by -1.

12x + 6y = 12
-12x - y = -22

The -12x and 12 x cancel each other out.

6y = 12
-y = -22
______
5y = -10
y = -2


Now that you have the value of y, you can plug it into the original equation.

4x + 2y = 4
4x + 2(-2) = 4
4x - 4 = 4
4x = 8
x = 2

So, your final answer is (2, -2).

Last weekend, Abigail collected 7 times as many trading cards as Trey. Together, they collected 40 trading cards. How many trading cards did Abigail collect?

Answers

Answer: 35 trading cards

Step-by-step explanation:

Assume the trading cards collected by Trey is x.

That means that the number of trading cards collected by Abigail is 7x.

Relevant expression is:

7x + x = 40

8x = 40

x = 40/8

x = 5 trading cards

This means that Trey collected 5 trading cards

Abigail collected 7 times that figure so Abigail collected:

= 7 * 5

= 35 trading cards

Answer:

1.) The 1ˢᵗ three term is (-32), (-7) and 18

2.) The 1ˢᵗ three term is 127, 106 and 85

Step-by-step explanation:

1.)

Here,

First Term = a₁ = - 32

Common Difference = (d) = 25

Now, For 1ˢᵗ three term,

n = 1

a₁ = - 32

n = 2

aₙ = a + (n - 1)d

a₂ = (-32) + (2 - 1) × 25

a₂ = (-32) + 1 × 25

a₂ = (-32) + 25

a₂ = -7

n = 3

aₙ = a + (n - 1)d

a₃ = (-32) + (3 - 1) × 25

a₃ = (-32) + 2 × 25

a₃ = (-32) + 50

a₃ = 18

Thus, The 1ˢᵗ three term is (-32), (-7) and 18

2.)

Here,

First Term = a₁ = 127

Common Difference = (d) = -21

Now, For 1ˢᵗ three term,

n = 1

a₁ = 127

n = 2

aₙ = a + (n - 1)d

a₂ = 127 + (2 - 1) × (-21)

a₂ = 127 + 1 × (-21)

a₂ = 127 - 21

a₂ = 106

n = 3

aₙ = a + (n - 1)d

a₃ = 127 + (3 - 1) × (-21)

a₃ = 127 + 2 × (-21)

a₃ = 127 - 42

a₃ = 85

Thus, The 1ˢᵗ three term is 127, 106 and 85

Sales Tax: At the movie theater, a bucket of popcorn costs $8.00 and a soda costs $2.50. How much will you pay in sales tax if the rate is 6%?

Answers

We have to pay $0.63 sales tax if the rate is 6%.

What is the sales tax?

Sales tax is a tax that is added to the price of goods or services when they are sold. It is typically a percentage of the purchase price and is collected by the seller from the buyer.

In this case, the price of the bucket of popcorn is $8.00 and the price of the soda is $2.50. If the sales tax rate is 6%, the total amount of sales tax paid on the popcorn would be $8.00 x 6/100 = $0.48 and on soda is $2.50 x 6/100 = $0.15. So the total amount of sales tax paid on both items is $0.48 + $0.15 = $0.63

Hence, we have to pay $0.63 sales tax if the rate is 6%.

Amy scheduled herself from 8am-1pm sunday through wednesday on wednesday she needed to release her intervals from 11am-1pm at the last minute she serviced all of the other time for which she posted what was her overall commitment adherence percentage?

Answers

Answer:

Commitment Adherence Percentage = 81.[tex]\overline{81}[/tex]%

Step-by-step explanation:

The time period Amy scheduled herself, t = 8 a.m. - 1 p.m. from Sunday through Wednesday

The period she released her interval = 11 a. m. - 1 p.m.

Commitment Adherence Percentage = Service Minutes/(Posted Minutes + Released Lockdown Minutes) × 100

Posted minutes = 5 hours/day × 60 minutes ×  4 days = 1200 minutes

Serviced minute = 5 hours/day × 60 minutes ×  3 days + 3 hours × 60 minutes/hour = 1,080 minutes

Released minutes = 2 hours × 60 minutes/hour = 120 minutes

Commitment Adherence Percentage = (1,080/(1,200 + 120)) × 100 = 81.[tex]\overline{81}[/tex]%

Answers

Answer:

Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.

Step-by-step explanation:

From. The plot given :

We could approximate the proportion of females older than 60 as follows _

COUNTRY A :

60 - 69 = 0.105

70 - 79 = 0.065

80 - 89 = 0.038

90+ = 0.01

Total = About 0.218

COUNTRY B :

60 - 69 = 0.14

70 - 79 = 0.11

80 - 89 = 0.07

90+ = 0.02

Total = About 0.34

From the estimated proportion, the proportion of females on country B is more than the proportion in country A.
