7a-3(2a-4) what’s the answer?

Answers

Answer 1

Answer:

?

Step-by-step explanation:

Answer 2

Answer:

a+12

Step-by-step explanation:

Distribute the -3 to (2a-4) so you get -6a+12

then it is 7a-6a+12, which is a+12.

If you need an actual number then a+12=0 is a=-12, if you just needed to simplify it, then a+12

Answers

Answer:

95⁰

Step-by-step explanation:

next time you want to figure this out, here's how

- they are supplementary angles, so you just subtract 45⁰ from 180⁰

180-45=95

so, you would get the answer 95⁰

for next time, you might not have as much information as you do in this equation so be careful

hope this helps!

Answer:

70

Step-by-step explanation:

Since this is supplementary, these two angles add up to 180 degrees. Therefore:

180 - 45 = 135

135 = 2x - 5

140 = 2x

x = 70

A rectangle has a perimeter of 80. if the length is four more than twice the width, what is the length of the rectangle ​

Answers

Answer:

28

Step-by-step explanation:

l = length

w = width

p = perimeter

w = w

l + l + w + w = p (adding all the rectangle's sides together gets us our perimeter)

l = 2w + 4 (four more than twice the width)

Substitute 2w + 4 for 'l' in the original equation

(2w + 4) + (2w + 4) + w + w = 80

Solve equation normally:

6w + 8 = 80

6w = 72

w = 72/6 = 12

(w = 12)

Length = 2w + 4

Substitute 12 for 'w':

2(12) + 4 = l

24 + 4 = l

28 = l

The length is 28

Answers

Answer: 45 divided by 3 equals 15

he has 15 dollars

Step-by-step explanation: 45= 3 times 15

Answer: 45=3a   a=15

Step-by-step explanation:

We know that Molly has $45 or 3 times the amount of money her brother has, and a represents the amount of money her brother has. So we would multiply a by 3. In order to find a we just divide 45 by 3.

Answer:

Amswer is A

Step-by-step explanation:

A transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°. What is the value of x?

Answers

Answer:

x=116°

Step-by-step explanation:

If a transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°, then the sum of those angles is equal to 180°.

ATQ,

x°+(x-52)°=180°

2x=180°+52

⇒2x=232

⇒x=116°

So, the value of x is 116°

Anyone know how to do this??

Answers

Answer:180=x-5+2x+5 180=3x (cancel 5 with negative5)x=180/3x=60

Answer:

x = 60

Step-by-step explanation:

In order to make L parallel (||) to M, you want to prove that the angles are same-side interior angles since the Same-Side Interior Angle Theorem only works for parallel lines cut by a transversal.

In order to make the angles (marked with the expressions) same-side interior angles, they have to add up to 180 degrees because they are supplementary angles.

Make an equation where the two angles add up to (equal) 180.

(x - 5) + (2x + 5) = 180

Combine like terms on the left side of the equation.

3x = 180

Divide both sides of the equation by 3.

x = 60

60 is the value of x that will make L || M.

if you look at the diagram, the added bonus is 6% of the base salary.

6% can be rewritten as 0.06

0.06 * 21,000 = 1,260

the total salary is just the base salary and the bonus salary added together.

21,000 + 1,260 = 22,260
