Answer:
2 hours
Step-by-step explanation:
Downers grove = 5 inches of snow + 6 inches every hour
= 5 + 6h
Woodridge = 13 inches + 2 inches every hour
= 13 + 2h
Where,
h = number of hours
In how many hours will the snowfall of the towns be equal?
Equate the snow falls of the towns
Downers grove = Woodridge
5 + 6h = 13 + 2h
Collect like terms
5 - 13 = 2h - 6h
8 = 4h
Divide both sides by 4
h = 8 / 4
= 2
h = 2 hours
The snowfall of the towns will be equal in 2 hours
Answer:
11 degrees.
Step-by-step explanation:
<em>"Angles T and U are a linear pair. Angle U measure (9x+6) and Angle T measures(6x+9). What is the value of x, in degrees?"</em>
We know that a linear pair MUST add up to 180 degrees, therefore (9x+6)+(6x+9)= 180
Now for some algebra-
(9x+6)+(6x+9)= 180
6 and nine can both be divided by 3, so we will do that for simplicity:
((9x+6)+(6x+9)= 180)/3=
(3x+2)+(2x+3)=60
We will now separate the parenthesis, as they serve no purpose anymore.
(3x+2)+(2x+3)=60
3x+2+2x+3=60
Combine terms
5x+5=60
Take away the 5 to isolate the variables
5x+5=60
-5
5x=55
Divide by 5
5x=55
/5
x=11
The value of x is 11 degrees.
