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
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.




Therefore, since the area of a square is the side length squared, the area of this square is 72. Hope this helps!
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!!
Answer:
Step-by-step explanation:
1/2
6
Step-by-step explanation:
Step 1:
Let Rachel scored 33 points in total
Let a be the 1 point and b be the 2 point.
a = 21 points scored by 1 point. We want to find b
Step 2:
a+b=33
b= 33-a
= 33-21
= 12
b=12 points which means 6 double points
