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
Which expression represents a negative value?
2 - |-7 + 31

Molly has $45 in her wallet, which is 3 times as much money as her brother has.
Write an equation to represent this situation, where a represents the amount of money Molly’s brother has.
45 =
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.
A rectangle has a perimeter of 80. if the length is four more than twice the width, what is the length of the rectangle
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
What is the value of x?
edge2020
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 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?
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°

What happens when the scale factor is less than 1? What happens when the scale factor is greater than 1?
Answer:
When the absolute value of the scale factor is lower than 1, it decreases the size of the shape.
When the absolute value of the scale factor is greater than 1, the shape will increase in size.
How to Remember it:
Think if the number is a fraction, the shape will be a fraction of the size.
Please help I’m confused. Thanks ;)

B)$136.00
C) $129.00
D)$197.80
Answer:
c i think sorry if im wrong
Step-by-step explanation:
Anyone know how to do this??
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) = 180Combine like terms on the left side of the equation.
3x = 180Divide both sides of the equation by 3.
x = 6060 is the value of x that will make L || M.

Answer:
Mark's total salary is 22,260
Step-by-step explanation:
well, his base salary is 21,000.
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

what is the area of this parallelogram?
30 inches squared or 30 in^2
All you have to do to find area of a parallelogram is length times width
So 5 times 6 is 30
Don’t forget the unit, which in this case is inches, and anytime you have area, you have to have a squared, or an exponent 2
Hope this helps, and please consider marking branliest if this did.
