Answer:
2.46
Step-by-step explanation:
cuz
<span>4 hours after they leave Houston.
Easiest way to solve this problem is to first calculate the relative velocities of the two buses. Since they're traveling in opposite directions, you simply need to add their respective velocities to see what the relative velocity is between them.
55 mi/h + 45 mi/h = 100 mi/h
That means that the buses will increase their distance apart from each other by 100 miles for every hour that they travel. So divide 400 miles by 100 miles/hour
400 miles / 100 miles/hour = 4 hours.
So 4 hours after the buses start moving, they will be 400 miles apart from each other.</span>
The brackets make the answer positive so you were just do 48÷6 which is 8and then 35÷7 which is five and you add 8+5 and you get 13
Answer:
x=-2
Step-by-step explanation:
divide both sides by 3
you get x=-2
go to -2 on the x axis and draw a line straight down, x=-2 will intercept the x axis at the point -2
same thing for y=-5 (example)
go down five on the y axis and draw a horizontal line to the y axis intercepting at point (0,-5)
Answer:
m∠1 = 52°
m∠3 = 52°
Step-by-step explanation:
Step 1:
Since b is a straight line and is transversed by line m and we are given m∠6 = 128°, we can find m∠5, which is 180 - m∠6, giving us 52° for ∠5.
Step 2:
Because a and b are parallel, m∠5 and the m∠1 are the same, so we have m∠1 = 52° as one of our answers needed
Step 3: Because ∠3 is vertical to ∠1, we can use the vertical angles theory and say that m∠1 is equal to m∠3. Therefore, m∠3 = 52°
