Answer: 62.5%
Step-by-step explanation:
Given
Ms. Savage ate of her lunch
i.e. she ate 5 parts of lunch out of 8
In percentage, it is expressed as
We have the equation: rg = 2 x rh - 10 and rg + rh = 415;
We solve them: rg = 2 x rh - 10 and rg = 415 - rh;
Then, 2 x rh -10 = 415 - rh;
Finally, 3 x rh = 425;
rh = 425 ÷ 3;
rh = 141,66 (the number of rooms at hotel h). There is something wrong with this number and there is something wrong with the this problem!!!
X^2 + 4x = 0
x^2 + 4x + 4 = 0 + 4
(x + 2)^2 = 4
The part of the expression without the variable is the constant, so in this case it would be 4
Answer:
m∠1 = 99°
Step-by-step explanation:
∠2 and ∠81° are Corresponding Angles, so they are equal to each other:
∠2 = 81°
∠1 and ∠2 are Supplementary Angles, so they add up to 180°:
180 - m∠2 = m∠1
180 - 81 = 99°
