Answer:
I honestly was having the worst time trying to solve this sorry :(, for real idk if any of these are right
i got 2 answers; 1st: ≈0.5 mph
the 2nd; 2 mph
Step-by-step explanation:
Speed = 
2/3 miles = 3520 feet
1/3 hours = 20 minutes
------Make a proportion-----
cross multiply------
3520 * 60 = 211200
5280 * 20 = 105600
Divide 
---(this is where i got confused cuz 2 doesn't make any sense)--
If you flip them, 
which makes more sense
hope i helped :(
You're given that there's 152 students. Each student has 18 pencils. All you have to do is multiply 152 students x 18 pencils/student, to get 2,736 pencils.
ANSWER
The solution is
x=-3,y=-2
EXPLANATION
First equation
3x – 3y = –3
Second Equation:
5x – y = –13
Multiply the second equation by 3 to get:
Third equation:
15x-3y=-39
Subtract the first equation from the third equation:
Divide both sides by 12,
Put x=-3 into the first equation:
Group like terms,
The solution is
x=-3,y=-2
Answer:
D. 21.
Step-by-step explanation:
The general form of the equation of a circle is:
(x - a)^2 + (y - b)^2 = r^2 where r is the radius.
Comparing:
(x + 5)^2 + (y + 7)^2 = 21^2
So r^2 = 21^2
making r = √21^2
= 21.
