Answer:
See below ~
Step-by-step explanation:
<u>Let</u> :
- x = people donating $15 when you run
- y = people donating $25 when you run
<u>Two inequalities created are</u> :
- 15x + 25y ≥ 1500
- 3x + 5y ≥ 300 [Simplified] ⇒ Inequality 1
- x + y ≤ 100 ⇒ Inequality 2
<u>Solving</u>

Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.

Subtract 60 from both sides and factor the quadratic to solve for w.

Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
There is no y intercept since there are no points on y axis so?
Answer:
m = √n/3 -k
Step-by-step explanation:
√n = 3(k + m)
=> √n/3 = k + m
∴ m = √n/3 -k
Hope this helps!!
