Answer:
3 steps
Step-by-step explanation:
FIrst of all, if you think about it, we can just say -3 as 3 ( even though they are not equal, were just counting steps.)
On a number line, negative numbers are on the left of 0 and positive on the right of 0.
So, lets say the middle number is 0 on our number line. -3 is 3 steps to the left. We take 1 step to negative 1, another step to -2, and then a 3rd and final step to -3.
The steps represent how far the number is from 0. FIr example, we have to add 3 to -3 to get to 0, like how we add 7 to 0 to get 7!
Hope this helps!
Recall your d = rt, distance = rate * time
the buses are traveling in opposite directions, but both are taking off at the same time
let's say bus A is going at 63mph and bus B is going at 62mph, so, we know their "r" rate for each
ok, after they had travelled for "t" time, they're both 187.5 miles apart, at that instant, bus A has been travelling for "t" hours and bus B has been also travelling for "t" hours as well
now, if bus A covered say "d" miles in those "t" hours, then bus B covered the slack from 187.5 and "d", or 187.5 - d
thus
![\bf \begin{array}{lccclll} &distance&rate&time\\ &-----&-----&-----\\ \textit{bus A}&d&63&t\\ \textit{bus B}&187.5-d&62&t \end{array} \\\\\\ \begin{cases} \boxed{d}=63t\\ 187.5-d=62t\\ ----------\\ 187.5-\boxed{63t}=62t \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Blccclll%7D%0A%26distance%26rate%26time%5C%5C%0A%26-----%26-----%26-----%5C%5C%0A%5Ctextit%7Bbus%20A%7D%26d%2663%26t%5C%5C%0A%5Ctextit%7Bbus%20B%7D%26187.5-d%2662%26t%0A%5Cend%7Barray%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Cbegin%7Bcases%7D%0A%5Cboxed%7Bd%7D%3D63t%5C%5C%0A187.5-d%3D62t%5C%5C%0A----------%5C%5C%0A187.5-%5Cboxed%7B63t%7D%3D62t%0A%5Cend%7Bcases%7D)
solve for "t".
Answer:
A. 60°
Step-by-step explanation:
There's a very straight-forward explanation for this, thank god! XD
For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.
180-120 = 60
60 is your answer because it completes the whole angle.

Answer:
Point Z
Step-by-step explanation:
If the x is -0.5, it is 0.5 to the left and when the y is 0.75 is is 0.75 up.
