Y=15x+45
150=15x+45
-45 -45
105=15x
105/15=15x/15
7=x
7 hours
Answer:
2 hours
Step-by-step explanation:
variable x = hours
fix it fast: 25 + 50x
do it right: 35 + 45x
25 + 50x = 35 + 45x
subtract 45x from both sides
subtract 25 from both sides
(this action cancels out 45x on the right side and 25 on the left side so you can combine like terms)
50x - 45x = 35 - 25
5x = 10
divide by 5 on both sides
x = 2
No. Since you can only draw from the corners to get triangles, you will end up with two right triangles because of the corners. If it is a right triangle, it can obviously not be obtuse.
Answer:
The answer is y = 5.25
Step-by-step explanation:
-2.3 + 1.6y = 6.1
1.6y = 6.1 + 2.3
1.6y = 8.4
y = 8.4/1.6
y = 5.25
