Step-by-step explanation:
(120÷20)÷(2×3)
6÷(2×3)
6÷6
1
h(r+1)
q could be 6 and it can be substituted with h
Step-by-step explanation:
Write what you know
mean is: Sum of all data points / Number of data points
any unknown number we'll call x
so youd write
(x + $3191) / 2 = $4444
Solve for x

Answer:
≈ 113.1 in³
Step-by-step explanation:
The figure comprises of a cylinder and a cone.
- V cylinder = bh= πr²h
- V cone = 1/3bh = 1/3πr²h
Total volume is:
- V = π*2²*8 + 1/3π2²*3 ≈ 113.1 in³
Using elimination method, the value of system of equations x = 1 and y = -3.
<h3>How to solve the equations by the
elimination method?</h3>
When solving a system of equations using the elimination method, the first step is to make the coefficient of one of the variables to be equal.
Given;
2x + y = -1
4x - y = 7
Add both the equation, we get
2x + y + 4x - y = -1 + 7
6x = 6
x = 1
Also,
2x + y = -1
y = -1 - 2
y = -3
Therefore, the value of x = 1 and y = -3.
