One hose can fill the pond in 30 minutes, which means every minute it fills 1/30 of the pond.
the second hose can fill the pond in x minutes, which means every minute it fills 1/x portion of the pond.
together it fills the WHOLE pond in 21 minutes: 21/30 +21/x=1
21/x=1- 21/30=9/30=3/10
x=70
Answer:
0
Step-by-step explanation:
Look at the numerator. Plug in 8 to m. 8-8 = 0, so the answer is 0.
The solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have an inequality:
−14a ≥ 42
-a ≥ 3
a ≤ -3
a ∈ (-∞, -3]
Thus, the solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.

First we define variables:
x = distance traveled by player A
y = distance traveled by player B
We have the following system of equations:
x + y = 1550
x = 9y
Solving the system we have:
x = 1395
y = 155
Answer:
x = 1395 yards (player A)
y = 155 yards (player B)
