Answer:
-2
Step-by-step explanation:
5(2z + 4) = 0
Divide both sides by 5.
2z + 4 = 0
Subtract 4 from both sides.
2z = -4
Divide both sides by 2.
z = -2
Answer:
3/10, or 0.3, or 30%
Step-by-step explanation:
1/5=2/10
2/10+1/10=3/10
The solution is 7/3. Sorry for no work, I can't think of how to explain it.
Answer:
x = sqrt(55)
x = 7.416198487
Step-by-step explanation:
We can use the Pythagorean theorem
The base is 3 (1/2 of 6). The other leg is x and the hypotenuse is 8
a^2 + b^2 = c^2
3^2 + x^2 = 8^2
9 + x^2 = 64
Subtract 9 from each side
9-9 +x^2 = 64-9
x^2 = 56
Take the square root of each side
sqrt(x^2) = sqrt(55)
x = sqrt(55)
x = 7.416198487
