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

Answer:
Hello! answer: 85
Step-by-step explanation:
68 × 68 = 4624
51 × 51 = 2601
4624 + 2601 = 7225
√7225 = 85
85 × 85 = 7225 therefore c = 85 Hope that helps!
Well your equation would be 40 = 2x + 16 so subtract 16 from both sides and that’s 24=2x then divide both sides by two so the length of the rectangle is 12.
