Answer:
Step-by-step explanation:
Distribute the -5 to x and -1
-5x+5=2x+15
Subtract 5 from 15
-5x= 2x +10
Subtract 2x away from -5x
7x= 10
Divide
X= - 1.428571429
DH = HF
x + 1 = 3y
y = (x + 1) ⁄ 3
GH = HE
3x – 4 = 5y + 1
y = (3x – 5) ⁄ 5
y = y
(x + 1) ⁄ 3 = (3x – 5) ⁄ 5
5x + 5 = 9x – 15
4x = 20
x = 5
y = (x + 1) ⁄ 3
y = (5 + 1) ⁄ 3
y = 2
Answer:
A. 5:3
Step-by-step explanation:
There are 10 blue and 6 red so that's 10:6
Reduce it to get 5:3

Answer:
8x + 60
Step-by-step explanation:
4(x + 5) + 2(x - 10) + 2(x + 30)
= 4x + 20 + 2x - 20 + 2x + 60 (combine like terms)
= 8x + 60
250/5/8 = 250 × (8/5)
= 400
So, a sloth may move 400 units per hour.
In other words, a sloth may move in 400 units per 60 minutes.
So, it will move = 200 units per 30 minutes.
Therefore, it will move (400 + 200) units per (60 + 30) minutes.
Hence, in 90 minutes, the sloth may move 600 units.
