Answer:
<h2>Earing is $13</h2><h2>Necklace is $10</h2>
Step-by-step explanation:
Firstly, let us express the cost
for Li
5e+n=63---------1
for Jen
e+2n=36---------2
the system of equations are
5e+n=63----1
e+2n=36-----2
Multiply 1 by 1 and 2 by 5 to eliminate e we have
5e+n=63
5e+10n=180
-0-9n=-117
9n=117
Divide both sides by 9 we have
n=117/9
n=13
put n=13 in eqn 1 we have
e+2(13)=36
e+26=36
e=36-26
e=10
Earing is $13
Necklace is $10
so we know that 9 friends are going to a movie right. So what we are going to do in this problem is you are going to divide 83.25 ÷ 9. and then you will find out how much they each paid. So each person will pay 9.25.
hope that helped
Let the height of the trees are h1,h2 and h3,
Then,we know that
Mean height=(h1+h2+h3)/3
Let x = number of problems on test
If he got 14 wrong, then x - 14 is the number correct.
x - 14 = .72x
.28x - 14 = 0
.28x = 14
x = 50
The test consisted of 50 problems.
The area is 4 x 6.5 which is 26
