A. Multiply the top equation by 15 and the bottom equation by 7.
B. Multiply the top equation by 1/3.
O C. Multiply the top equation by 3 and the bottom equation by 4.
D. Multiply the top equation by-3 and the bottom equation by 2.

Answers

4x – 2y=7

3x – 3y = 15

we want to keep y by eliminating the x

so we will Multiply the top equation by 3 and the bottom equation by 4.

we will get

12x - 6y = 21

12x - 12y = 60

we subtract the equations

12x - 6y - 12x - (-12y) = 21 - 60

6y = -39 and so on

In three days Alexandra sold a total of 31 tickets to her school play. On Tuesday she sold as twice as many tickets as on Wednesday. And on Thursday, she sold exactly seven tickets. How many tickets did Alexandra sell on each day Tuesday through Thursday?

Answers

Answer:

Alexander sold

8 tickets on Tuesday

16 tickets on Wednesday

7 tickets on Thursday

Step-by-step explanation:

Let us represent:

Number of tickets sold on Tuesday = a

Number of tickets sold on Wednesday = b

Number of tickets sold on Thursday = c

In three days Alexandra sold a total of 31 tickets to her school play.

a + b + c = 31...... Equation 1

On Tuesday she sold as twice as many tickets as on Wednesday.

2a = b

And on Thursday, she sold exactly seven tickets.

c = 7

Substitute 2a for b and 7 for c in Equation 1

a + b + c = 31...... Equation 1

a + 2a + 7 = 31

3a = 31 - 7

3a = 24

a = 24/3

a = 8 tickets

Note that

2a = b

a = 8 tickets

2 × 8 = 16 tickets

b = 16 tickets

Therefore, Alexander sold

8 tickets on Tuesday

16 tickets on Wednesday

7 tickets on Thursday

In a properly drawn sample with a 3-percent sample error, 20% of 100 respondents indicate they intend to vote for a ballot measure. This means that there is high probability that between ______ percent of all voters actually plan to vote for the ballot measure.

Answers

The true statement is that, the probability that 17% to 23% percent of all voters planned to vote is high

How to determine the probability?

The percentage sample error (S) is given as:

S = 3%

The proportion (p) of the respondent is given as:

p = 20%

This means that the range (R) of the proportion is:

R = p ± S

This gives

R = 20% ± 3%

Expand

R = (20% - 3%, 20% + 3%)

Evaluate

R = (17%, 23%)

This means that the range is 17% to 23%

a furniture company currently produces 5800 chairs per month. If production decreases 5%, find the amount of the decrease and the new number of chairs produced each month.​

Answers

Answer:amount of decrease 290 ;numbers of chairs 5510

Step-by-step explanation:

Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Number of chairs produce in a month = 5800

5% decrease in production:

= 5% of 5800

= 5/100 x 5800

= 5 x 58

= 290

The number of new chairs produced each month:

= 5800 - 290

= 5510

Thus,

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.
