The answer is B
2x+5y=3(1) times it by 1
-x+3y=-7(2) times it by 2
____________________
2x+5y=3
-2x+6y=-14
__________
11y=-11
Y=-1
Now we have to found x..... you have to plug in -1 in 2x+5y=3...
2x+5(-1)=3
2x-5=3
2x=3+5
2x=8
X=8/2
X=4
There are your 2 solutions... hope you understand
Here's the whole equation;
tldr divide -6 by -2 and flip the inequality from < to >.
<h2>
Option C is the correct answer.</h2>
Step-by-step explanation:
Diameter, D = 42 feet
Circumference = πD = π x 42 = 131.95 feet
Number of rotations per minute = 3
Total time = 5 minutes
Total rotations = 5 x 3 = 15
Distance traveled per rotation = 131.95 feet
Distance traveled in 15 rotations = 15 x 131.95 = 1978 feet
Option C is the correct answer.
Answer:
q=45
Step-by-step explanation:
To do this we have to isolate q.
q is being divided by 3, so to reverse that we have to multiply it by 3.
However, in an equation, what you do to one side, you must do to the other. This is so the equation stays equal.
15=q/3
That said, what we can do is multiply the entire equation by 3.
45=q
So the solution to the equation is 45.
