Answer:
Step-by-step explanation:
Step 1: Sum of angles on a straight line is 180
Step 2:
2x + 25 + y = 180
2x + y = 180 - 25
2x + y = 155 (1)
Step 3:
3x - 10 + y = 180
3x + y = 180 + 10
3x + y = 190 (2)
Step 4: Substract equation 1 from 2
3x + y - 2x - y = 190 - 155
x = 35
Step 5:
Substitute x in equation 1 to find y
2x + y = 55
2(35) + y = 155
70 + y = 155
y = 155 - 70
y = 85
50 I think. 2 1/2 times 20 minutes equals 50
Answer:
16
Step-by-step explanation:
Hope you get it.
You would just convert 5 1/3 into a improper fraction 16/3=16/3
Neither...
205/1000 equals .205
So they are both the same.

option 4
Notice that 3 is multiplied on both sides on of the equation to get
5x+6 = -9
