Carol bought 2 pairs of jeans at 24 each and 3 shirts she spent a total of 75 before tax what is the cost of 1 shirt
Ratling [72]

Answer:$9

Step-by-step explanation:Here's what we know:

2 * 24 + 3s = 75 (the pants ($24 each) and shirts all together is $75)

 

What we need to do is isolate s

Simplify:

48 + 3s = 75

subtract 48 from both sides:

48 + 3s - 48 = 75 - 48

3s = 27

Divide by 3:

3s / 3 = 27 / 3

s = 9

 

Shirts are $9 each.

Given A(0, 0) and B(60, 60), what are the coordinates of point M that lies on segment AB such that AM:MB = 2: 3?
elena-14-01-66 [18.8K]
The answer is (24, 24).
Solution:
To find the point M that divides segment AB into 2:3 or 2/3 ratio, we determine k by writing the numerator of the ratio over the sum of the terms in the given ratio. Then, we calculate for the coordinates of point M from the slope of the line segment and the coordinates of A = (x1, y1) = (0, 0) and B = (x2, y2) = (60, 60) using the equation
     (x, y) = (x1 + k(x2 - x1), y1 + k(y2 - y1) )
Therefore,
     M = (x, y) = (0 + (2/5)(60 - 0), 0 + (2/5)(60 - 0)) = (24, 24)

I NEED HELP! I've failed this test twice and need to get it right. HELP PLEASE!
vlada-n [284]

Answer:

180

Step-by-step explanation:

C + D = 180 degrees since they are a linear pair

D = 127 degrees, so

C + 127 = 180

to get the C, you need to subtract 180 degrees bt 127 degrees

180 - 127 = C
