please solve and explain, thanks!! :))

Answers

Answer 1

Answer:

Step-by-step explanation:

Its B because you distribute each term inside the parenthesis by the number out side

4×2x= 8x

4×3= 12

Get rid of the parenthesis after distributing

which makes 8x+12

Answer 2

Answer:

B. 8x + 12

Step-by-step explanation:

First you'd start with the parentheses because of PEDMAS. But because you can't do anything in there, you go to multiplying 4 by each item inside the parentheses. 4x2x gives 8x. 4x3 gives 12. Leaving you with 8x+12. Hope that helps! :)

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?

Answers

Answer:

$460.20

Step-by-step explanation:

499*15% = 74.85 (total discount price)

499-74.85 = 424.15 (deduct discount from original price)

424.15*8.5% = 36.05275 (total tax from price)

424.15+36.05275 = 460.20275 (add tax to discounted price)

the answer is $460.20

So start out with -5 then subtract -2 you get -3 then subtract 12-3 and get nine. That’s your answer 9. Hope this helps.

Since the slope is equal to -5 you can already get the beginning of the equation being y=mx+b; M=-5, now to find b you need to plug in your numbers: 12=-5(-2)+b then you get 12=10+b. subtract the 10 to find that b=2 then plug in all the numbers to find the answer y=-5x+2

Answer: [tex]Y = \frac{2}{3} x - 5[/tex]

Step-by-step explanation:

Answer: y=7.5+-5

Step-by-step explanation:

Divide 3y from itself and -15 to cancel out the Y variable. So Y is equal to -5. Then you would be left with -2x=-15. So then you would have to divide -2x from itself and -15, which would give you 7.5, and that is your x variable.

A band expects to put 12 songs on their next CD. The band writes and records 25% more songs than they expect to put on the CD. During the editing process, 20% of the songs are removed. How many songs will there be on the final CD?

12 songs. 25% of 12 is 3, so you add 3 to 12 and get 15. You then find that 20% of 15 is 3 so you subtract 3 from 15 and get 12 again.

In the diagram, the measure of angle 6 is 98°. A transversal intersects 2 lines to form 8 angles. Clockwise from top left, the angles are 1, 2, 3, 4; 5, 6, 7, 8. What is the measure of angle 7? °

Answers

Answer: 82°

Step-by-step explanation:

6 = 98°

180° - 98° = 82°

The measure of angle 7 is 82°.

What is the vertical angles' theorem?

According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.

Given:

In the diagram, the measure of angle 6 is 98°.

A transversal intersects 2 lines to form 8 angles.

Clockwise from the top left, the angles are 1, 2, 3, 4; 5, 6, 7, 8.

Angle 6 and Angle 7 are supplementary angles.

So,

m∠7 = 180 - 98

m∠7 = 82°

Therefore, m∠7 = 82°.
