Order the numbers from least to greatest. Then cross out the first number, then the last number, then the 2nd lowest number, then the second to last number, etc. until you get to the middle.
You should get an answer of 69.
C it’s what I chose for it
Answer:
A circle!
Step-by-step explanation:
Typically, for most 3 dimensional shapes, cutting parallel to the base will result in the shape that the base takes on. Because the base of a cylinder is a circle, the shape of a cross-section parallel to the base of a cylinder would be a circle.
The answer is B. I hope this helped.
The solution of the system of equations is (-3 , -2)
Step-by-step explanation:
Let us revise the steps of Linear combinations method
- Arrange the equations with like terms in columns
- make the coefficients of x or y equal in magnitudes and different in signs
- Add the equations and solve for the remaining variable
- Substitute the value of the variable into one of the two equations to find the second variable
The system of equations is
3 x - 8 y = 7 ⇒ (1)
x + 2 y = -7 ⇒ (2)
Let us make the coefficients of y equal in magnitude by multiplying
equation (2) by 4
∴ 4 x + 8 y = -28 ⇒ (3)
- Add equations (1) and (3) to solve for x
∴ 7 x = -21
- Divide both sides by 7
∴ x = -3
Substitute the value of x in equation (1) to find y
∵ 3(-3) - 8 y = 7
∴ -9 - 8 y = 7
- Add 9 to both sides
∴ -8 y = 16
- Divide both sides by -8
∴ y = -2
The solution of the system of equations is (-3 , -2)
