Answer:
x = 20
Step-by-step explanation:
→ Remember how many degrees are on a straight line
180°
→ Set up an equation
2x + 70 + 3x + 10 = 180
→ Simplify
5x + 80 = 180
→ Minus 80 from both sides
5x = 100
→ Divide both sides by 5
x = 20
I guess you want to calculate the value of e. If so then:
-8.e = 4 . Divide both sides by 4:
-2.e = 1. Divide both sides by 2:
-e = 1/2. Multiply both sides with (-):
e = - 1/2
Answer:
≈ 3.8928
Step-by-step explanation:
log base 3 of 72 is approximately 3.8928
you would need to plug this into a calculator to solve
It would be 81 or you can do 81/8 = 9
