Answer:
8x
Step-by-step explanation:
3x + 8x are like terms which means they have the exact same variable.
To add like terms we add the coefficients which are 3 and 5.
3 + 5 = 8
We have 8 x's. So 3x + 5x = 8x.
In order to add terms, the variable part has to be exactly the same.
It's like saying 3 balls + 5 balls = 8 balls.
This is a work problem. It can be solved as follows:
Houston = 1/x
Dominique = (1/2x)
Together = 1/5
Then, we add Houston and Dominique:
1/x + 1/2x = 1/5
Solve for x,
x = 2/15
Therefore, it would take 15/2 hours for Houston to ice by himself, the last option.
(5/8) × 48 = (8/15) × n
Multiply by the inverse of the coefficient of n. That inverse is 15/8.
n = (15/8)×(5/8)×48 = (75/64)×48 = 225/4 = 56 1/4
5/8 of 48 is equal to 8/15 of 56 1/4
Answer: Angle B is 22 and angle A is 158
Step-by-step explanation: I hope this helped!
The six sides would be:
2 sides of 14*4=56cm^2, 112 in total
2 sides of 4*6=24cm^2, 48 in total
2sides of 14*6=84cm^2, 168 in total
112+48+168=328cm^2
