Answer:
Step-by-step explanation:
143=5x+13(being corresponding angles)
143-13=5x
130/5=x
26=x
Answer: 9 cm
Step-by-step explanation:
The volume of a pyramid is calculated by the formula:
Volume = (Length * Width * Height ) / 3
Filling in the details from the question will give:
124.2 = (9 * 4.6 * h) / 3
Solve for h:
9 * 4.6 * h = 124.2 * 3
41.4h = 372.6
h = 372.6 / 41.4
h = 9 cm
Answer:
x = or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)
