what is the solution for 3х + y = -5
[tex]\tt Step-by-step~explanation:[/tex]
[tex]\tt Solve~for~y:[/tex]
To solve for y, we have to move all of the terms that do not equal to y on one side, and let y be on the other side alone. Do this by subtracting 3x on both sides to cancel it out from the left side and bring it to the right.
[tex]\tt 3x-3x+y=-5-3x\\y=-5-3x\\y=-3x-5[/tex]
[tex]\tt Solve~for~x:[/tex]
To solve for x, we will do the same thing we did to solve for y: move all the terms that do not equal to x to one side, and leave x on another side of the equation. We can do this by first subtracting y from both sides.
[tex]\tt3x+y-y=-5-y\\3x=-y-5[/tex]
Then, we divide all terms by 3 to isolate the x.
[tex]\tt \frac{3x}{3}=x\\\\ \frac{-y}{3}=\frac{-y}{3} \\\\\frac{-5}{3}=\frac{-5}{3}[/tex]
[tex]\tt x=-\frac{y}{3} -\frac{5}{3}[/tex]
[tex]\lare\boxed{\tt Our~final~answer:~y=-3x=5,~x=-\frac{y}{3}-\frac{5}{3} }[/tex]

What is the volume of a cone with a radius of 4 centimeters and a height of 5 centimeters? please help
Answer:
V = [tex]\frac{80\pi }{3}[/tex]
Step-by-step explanation:
Using the equation for finding the volume of a cone
V = [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
Were "V" is Volume, [tex]\pi[/tex] is pi, r² is radius to the second power, and [tex]\frac{h}{3}[/tex] is height divided by 3.
We can fill in the missing components to find "V" as in for Volume.
V = [tex]\pi[/tex]4²[tex]\frac{5}{3}[/tex]
Now let's simplify
V = 16[tex]\pi \frac{5}{3}[/tex]
Now simplify for the last time
V = [tex]\frac{80\pi }{3}[/tex]
Hope this helped!

Answer: V = 1649.34
Step-by-step explanation:
The formula for solving the volume of a right cylinder is V = pi r^2h where r = radius and h = height.
We know that radius is half the diameter so r = 5 because the diameter is 10 ft. We already know height = 21 so our equation looks like pi x 5^2 x 21
5^2 = 5 x 5= 25
so pi x 25 x 21 = 1649.34
Answer:
V ≈ 1649.34 ft³
Step-by-step explanation:
Volume of a Cylinder: V = πr²h
Diameter = 2 · radius
Step 1: Define
d = 10 ft
h = 21 ft
Step 2: Substitute and Evaluate
10 = 2r
r = 5
V = π(5)²(21)
V = π(25)(21)
V = 525π
V ≈ 1649.34 ft³

Answer:
2x+y=145 and x-y=55.
Step-by-step explanation:
Let x represent the smaller number and y represent the larger number.
ATQ,
The sum of twice a number and a larger number is 145.
2x+y=145 ...(1)
The difference between the numbers is 55.
x-y=55 ...(2)
Hence, the two equations that represent the situation are 2x+y=145 and x-y=55.
Answer:
C. 2x+y=145 D. y-x=55 E. y=x+55

24% is 120% of what number?
Answer:
Step-by-ste24 is 120% of [20]
I don't know if you meant 24 is 120% of x but if that is what you meant, then the answer would be 20. If you meant 24% is 120% of x then x=.2.
24 is 120% of 20 because 20*1.2=24
24% (AKA .24) is 120% of .2 because .2*1.2=.24 and .24=24%
