Answer:
x = 10/3
Step-by-step explanation:
1.Arrange both equations so that the constant is isolated
3x - 2y = 14
6x + y = 18
2. Multiply both sides of first equation by a value that will cancel out a variable when added to the second equation
(-2) 3x - 2y = 14 (-2)
-6x + 4y = -28
3. Add both equations together
-6x + 4y = -28
<u>+ 6x + y = 18</u>
0x + 5y = -10
4. Simplify
5y = -10
y = -2
5. Substitute y-value into one of the original equations to solve for x
3x = 2y + 14
3x = 2(-2) + 14
3x = -4 + 14
3x = 10
x = 10/3
Answer:
63 in²
Step-by-step explanation:
Area of a triangle = 1/2 × base × height
Given:
- base = 14 in
- height = 9 in
Substitute the given values into the formula:
⇒ area = 1/2 × 14 × 9
= 63 in²
Answer:
2255.31 cu.m
Step-by-step explanation:
Volume of a cylinder = πr²h
Given radius r = 6.5m
Height h = 17m
Volume = π × 6.5²×17
Volume = 3.14×6.5²×17
Volume of the cylinder = 2255.31cu.m
