Kyle earned 4 times as much as Ken last summer. If they earned a total of $750, how much did they each earn?
Sholpan [36]

Answer:

600, 150

Step-by-step explanation:

Kyle is x

ken is y

x = 4y

x+y = 750

replace x with 4y

4y + y = 750

5y = 750

y = 150

so ken earned 150

x + 150 = 750

x = 600

so Kyle earned 600

What is the area of the square
Greeley [361]

Answer:

72 square yards

Step-by-step explanation:

If half of the diagonal of a square is 6 yards, then the full diagonal is 12 yards, and then you can find the side length by using the Pythagorean theorem. You know that all of the sides of the square are equal, so let's call them s.

\sqrt{s^2+s^2}=12

2s^2=144

s^2=72

s=\sqrt{72}

Therefore, since the area of a square is the side length squared, the area of this square is 72. Hope this helps!

The measures of the angles of a triangle are shown in the figure below. Find the
dimaraw [331]

Answer:

318.6

Step-by-step explanation:

(3x-9) + (x+15) = 180

3x (x+15) -9 (x+15)

4x + 45x - 9x + 6 = 180

40x + 6 = 180

40x = 180 - 6

40x = 174

x = 4.34

(3x-9) = 4.34 * 3x-9 = 4.02

(x+15) = 4.34 + 15 = 19.34

180 - (4.02 + 19.34)

= 180 - 23.36

= 156.64

hope this answer helps!!
