This is two lines in slope intercept form and we want their intersection. We just set the ys equal.
-3x - 3 = (-1/2)x + 2
Multiply both sides by 2 to clear the fractions,
-6x - 6 = -x + 4
-10 = 5x
x = -10/5 = -2
y = -3x - 3 = -3 (-2) - 3 = 6 - 3 = 3
Check:
y = (-1/2)x + 2 = (-1/2)(-2) + 2 = 1 + 2 = 3, good
Answer: x=-2, y=3

Answer:
450
Step-by-step explanation:
We know that Cole did jump rope for 7 1/2 minutes.
In one minute there are 60 seconds. So we know that for each minute there is a 60 in it.
So, 7 x 60 = 420 then a half minute is thirty seconds (we know this because half of sixty is thirty.)
So we simply add 30 to 420 getting 450.
Answer:
2 
Step-by-step explanation:
for question a)
It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)
to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.
E.g.
7
= 7x4 + 1 = 29
Thus, improper fraction would be 
do same thing for other one
thus , 
now,
- 
however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)
= 
convert back to mixed number
