5/9, 2/15

Answers

Answer 1
Answer: LCD is least common denominator, also called least common multiple LCM
5/6, 2/9   LCD is 18
1/12, 3/8 LCD is 24
5/9, 2/15 LCD is 45

18, 24, and 45 are the least common multiples of the denominators for their own pair.

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?

Answers

We know from the question that Store A charges $1200 for repairs and 6% as sales tax.
Then
Amount of sales tax charged by Store A = (6/100) * 1200
                                                                 = 6 * 12
                                                                 = 72 dollars
Then the total amount charged by Store A = ( 1200 + 72) dollars
                                                                   = 1272 dollars
Now coming to Store B. It charges $1350 for repairs and 7% of sales tax.
Amount of sales tax charged by Store B = (7/100) * 1350
                                                                 = 945/10
                                                                 = 94.5 dollars
Then the total amount charged by Store B = ( 1350 + 94.5) dollars
                                                                     = 1444.5 dollars
Amount of money saved by choosing Store A instead of Store B = (1444.5 - 1272) dollars
                                                                                                       = 172.5 dollars
So $172.5 is saved by choosing Store A over Store B.

The total repair cost for each store is the cost of repairs added to the sales tax. The amount of money saved will be the difference between the two total costs.

Triangle M' is the image of triangle M under a dilation.What is the center of the dilation?
A
B
C
D

Answers

Since triangle M' is the image of triangle M under a dilation, the center of the dilation is: B. B.

What is dilation?

In Mathematics and Geometry, a dilation is a type of transformation that is used for altering the dimensions of a geometric figure, but not its shape.

Generally speaking, the coordinates of the pre-image can be dilated by using a scale factor that is centered at the point B by using this mathematical expression:

(x, y)  →  (k(x - a) + a, k(y - b) + b)

In conclusion, the center of the dilation would be at point B when the three vertex of both triangle M' and triangle M are connected.

2+4•5+1=26
Where do I put the parentheses to make the equation true

Answers

2 + ( 4 • 5 ) + 1 = 26 like this

Subtract a - 4$ from 4a + 16 and simplify your answer. The variable (A) should appear only once in your answer.

Answers

   4a + 16 - (a - 4)
= 4a + 16 - a + 4
= 3a + 20
4a + 16 -a + 4 = 3a + 20

24 is what percent of 60

Answers

Work is provided in the image attached.
100%/x%=24/60.
(100/x)*x=(24/60)*x - we multiply both sides of the equation by x.
100=0.4*x - we divide both sides of the equation by (0.4) to get x. 

hope this helps you understand.
best i could do.

Hope this helps ya!!

-3x - 3/4 = 9 helpppppppp

Answers

-3x - 3/4 = 9
-3x - 3/4 + 3/4 = 9 + 3/4
-3x = 9 3/4
I change 9 3/4 to improper fraction
-3x = 39/4
-3x / -3 = 39/4 / -3
X = 39/4 x -1/3 (change division to multiplication so that you can complete the problem)
X = -39/12
You can convert that if you want to -3 3/12
So x = -3 3/12
Simplify to x = -3 1/4
