Answer:
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the distance in miles
y ----> the time in hours
we have
The distance is equal to subtract 35 miles from 230 miles
The time is equal to subtract 1:30 pm from 4:30 pm
substitute in the formula of speed
<em>Isolate 3 hours</em>
<em>Isolate 195 miles</em>
Answer:
(3, - 1)
Step-by-step explanation:
5x - 4y = -11
2x + 3y = -9
Multiply the top equation by 2 and the bottom equation by - 5 to cancel out the x's.
10x - 8y = - 22
- 10x - 15y = 45
Cancel out x's.
-8y = - 22
- 15y = 45
Add like terms.
- 23y = 23
Can't have a negative variable to flip them.
-23 = 23y
Divide.
y = - 1
Input y into one of the equations and solve for x.
2x + 3(-1) = -9
Simplify.
2x -3 = -9
Cancel out -3 by adding 3.
2x = -6
Divide.
x - -3
Answer:
x = 12
Step-by-step explanation:
Remark
These two angles are corresponding angles and as such, they are equal.
Equation
8x+ 36 = 5x + 72
Solution
Subtract 5x from both sides
8x - 5x + 36 = 5x - 5x + 72 Combine like terms.
3x + 36 = 72 Subtract 36 from both sides
3x + 36 - 36 = 72 - 36 Collect like terms
3x = 36 Divide by 3
3x/3 = 36/3 Divide
x = 12 Answer
Answer:
6 hours 30 minutes
Step-by-step explanation:
morning work=3 hours 45 minutes
afternoon work=2 hours 45 minutes
total hours=?
Here,
3 hours 45 minutes+2 hours 45 minutes
=6 hours 30 minutes
Therefore,Terry Baelett worked 6hours 30 minutes a day.
