Answer:
90 miles!
Step-by-step explanation:
there are two parts to the problem, meaning you'll need 2 equations.
let's call the distance TO the grandma's house d1, and BACK from the grandma's house d2.
KEY:
time TO g'ma house= t1
time FROM g'ma house=t2
(replace the t's with 's' for speed, with the '1' for to, and '2' for from)
(distance is a constant so d1 is always equal to d2).
-------------
d1=s1+t1, d2=s2+t2
we know what t1 is. 2 hours.
d1=s1•2
meaning that d2 is also equal to that.
s1•2=(s1-5)•2 1/4
2s1=2 1/4 s1-11 1/4
11 1/4= 2 1/4 s1-2s1
11 1/4 = 1/4 s1
s1 (to g'ma)=45 mph
distance is speed times time.
so 45•2 (hr) = 90.

Jada volunteers at the animal shelter. She divided 5 cups of cat food equally to feed 20 cats. Each cat received x cups of food.
Answer choices:
x + 5 = 20
x = 20 + 5
5x = 20
x + 20 = 5
520 = x
20x = 5
There are 15 violinists in the orchestra this year. Next year, two violinists will leave and some new violinists will join the orchestra. If v is the number of violinists who will join the orchestra, which expression(s) represent the number of violinists in the orchestra next year.
A 15−2+v15 minus 2 plus v
B 15−v15 minus v
C v−2v minus 2
D 13+v13 plus v
E v−15v minus 15
F v+13
Answer:
A and D
Step-by-step explanation:
There are already 15. Take away 2 in the next year and also add some (v) in the same year.
13 + v is the simplified version of the original expression (15 - 2 + v)

David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left?
?
__
?
what percent?________%
Answer:
200/500=2/5
40%
Step-by-step explanation:
If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.
Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500
Then simplify=200/500 divided by 100/100 equals 2/5.
Then to get it to a percentage divide 2 by 5 which equals .40
Then convert to a percentage 40%

Two points defining a linear function are shown in the table below.
[tex]\left[\begin{array}{ccc}&x&y\\&-14&-18\\&-10&-12\end{array}\right][/tex]
How do u get the slope?
Slope in fraction form = 3/2
Slope in decimal form = 1.5
============================================================
Explanation:
That table shows the two points (x1,y1) = (-14,-18) and (x2,y2) = (-10,-12).
Each row is a different point.
To find the slope, we subtract the y values to get y2-y1 = -12-(-18) = -12+18 = 6
Then we subtract the x values to get x2-x1 = -10-(-14) = -10+14 = 4
Lastly, we divide the two differences: ydiff/xdiff = 6/4 = 3/2
The slope in fraction form is 3/2, which is equivalent to the decimal form 1.5
------------------------
If you want, you can apply the slope formula like so
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (-12-(-18))/(-10-(-14))
m = (-12+18)/(-10+14)
m = 6/4
m = 3/2
m = 1.5
We effectively are following the same as steps as before, but in this format, it's more of what you might have on your homework if you were to show the step-by-step process. You could also do a visual graph approach as a different option. Often in math there are multiple ways to get the answer.

Step-by-step explanation:
Write the equation of the line in fully simplified slope-intercept form.
Answer:
y=-1/2x-1
Step-by-step explanation:
the slope intercept form is y=mx+b
m=slope
b=y intercept (where the line crosses the y axis)
to find slope you do rise over run or rise/run
the rise of you slope is -1, and the run of your slope is 2, meaning your slope is -1/2
the line crosses the y axis at point -1
plug what you find into the slope intercept form, and you get y=-1/2x-1
