Answer:
(6, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + 5y = - 3 → (1)
2x + 2y = 6 → (2)
Subtracting (1) from (2) term by term will eliminate the x- term
(2x - 2x) + (2y - 5y) = 6 - (- 3), that is
- 3y = 9 ( divide both sides by - 3 )
y = - 3
Substitute y = - 3 in either of the 2 equations and solve for x
Substituting y = - 3 in (1)
2x + 5(- 3) = - 3
2x - 15 = - 3 ( add 15 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Solution is (6, - 3 )
M<2 = 60
m<1 = 180 - 60
m<1 = 120

The amount of candy that each of his 6 friends will get is 1/14 of a pound.
It is given in the question that James has 6 friends with those he has to share 1/2 pound of the candy.
We have to find the amount of candy each of his 6 friends gets.
We know that,
Total number of people among those the candy will be shared = James + 6 friends = 7 people
Total amount of candy with James = 1/2 pound
We know that,
Amount of candy each person gets = Total amount of candy/No. of people.
Hence,
Total amount of candy each person gets = (1/2) /7 =(1/2)*(1/7) = 1/14 of a pound.

The means is the average of a data set
Hey there!
When dealing with percent word problems, the word "is" means equals. Let's see what we can do with your problem.
If the small school had 60% boys, it will have 40% girls. The number of boys <em>is</em> 48, which should equal 60% of the total, which we can model below, with t representing the total number of kids. In decimal form, 60% is 0.6.
0.6t=48
We divide both sides by 0.6.
t=80
Therefore, there are 80 total kids at the school.
We can also check our answer below.
BOYS: 0.6(80)= 48
GIRLS: 0.4(80)=32
48+32=80
I hope that this helps!
