Solve for:
x
Let's solve for x.
−2x+2y=−2
Step 1: Add -2y to both sides.
−2x+2y+−2y=−2+−2y
−2x=−2y−2
Step 2: Divide both sides by -2.

x=y+1
Answer:
x=y+1
2. Let's solve for x.
3x+2y=8
Step 1: Add -2y to both sides.
3x+2y+−2y=8+−2y
3x=−2y+8
Step 2: Divide both sides by 3.
3x/3=-2y+8/3
x=-2/3 y+8/3

D) 354.18 cm2
I have a 10 question quiz that I'm really struggling on because i don't know how to work out problems like these, so if someone could please help me that would be great.
The area of the cylinder is the amount of space on it.
Using the assumed values, the lateral surface area of the cylinder is 314 square centimeter
How to determine the lateral surface area?The lateral surface area of a cylinder is:
L = 2πrh
The question is incomplete. Assume the following parameters
Radius, r = 10
Height, h = 5.
Then we have:
L = 2 * 3.14 * 10 * 5
Evaluate the product
L = 314
Using the assumed values, the lateral surface area of the cylinder is 314 square centimeter

a system of equations is shown. 4x-y=5 y=-3 what is the value of x in the solution to this system
Answer:
x = 1 / 2 ( or ) 0.5
Step-by-step explanation:
4x - y = 5
Substitute the value of y = - 3 in the given equation,
4x - ( - 3 ) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2 / 4
x = 1 / 2 ( in terms of fraction )
( or )
x = 0.5 ( in terms of decimal )
Note : -
- ( - 3 ) can be written as - 1 x ( - 3 ).
When a negative number is multiplied with another negative number, the result will be positive number.

A rectangle with a perimeter of 18 miles and a width of 7 miles.
What is the length of the rectangle?
Answer:
2 miles
Step-by-step explanation:
A rectangle has two widths
7 + 7 = 14
18-14=4
It also has two lengths
4/2=2
2 miles
Hope this Helps
Happy Earth day
Answer:
2 miles
Step-by-step explanation:
Perimeter is figured out by adding all 4 sides of a rectangle.
So if the width is 7 miles on 1 side, the other width side is also 7 miles.
If the perimeter was 18 miles and 14 miles of that was the width on both sides, that leaves only 4 miles left for the 2 length sides. That means each length side is 2 miles.

At a high school, the probability that a student is a senior is 0.25. The
probability that a student plays a
sport is 0.20. The probability that a student
is a senior and plays a sport is 0.08.
What is the probability that a randomly selected student plays a sport, given
that the student is a senior?
• A. 0.08
O B. 0.32
• C. 0.17
D. 0.25
Answer:
B. 0.32
I guessed and it was right
The probability that a randomly selected student plays a sport, given that the student is a senior, is 0.32.
The correct answer is B. 0.32.
To find the probability that a randomly selected student plays a sport, given that the student is a senior, we can use the formula for conditional probability:
P(plays a sport | senior) = P(plays a sport and senior) / P(senior)
Given that P(plays a sport and senior) = 0.08
and P(senior) = 0.25,
we can substitute these values into the formula:
P(plays a sport | senior) = 0.08 / 0.25
P(plays a sport | senior) = 0.32
Therefore, the probability that a randomly selected student plays a sport, given that the student is a senior, is 0.32.
