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: The length of the bottom left side is 14.
To find the length of this side, we need to know the relationship between the different sections when chords cross each other.
The relationship is that if you multiply the 2 parts of each chord together, it will equal the product of the two sides in the other chord.
Our equation can be written as:
7(8) = 4(x)
56 = 4x
14 = x
Answer:
10 + (-8)
Step-by-step explanation:
Subtracting is like adding a negative
10 -8
10 + (-8)
Answer:
y=3.5x
Step-by-step explanation:
to find the the feet mary walks per second, divide 14 by 4
14/4=3.5 feet/second
the total distance mary walks can be represented by multiplying the number of feet she walks per second by the number of seconds she walks
y= 3.5x
in this model, x is seconds
2k = 25
Divide 2 on each side
k = 12.5
Each pizza would cost $12.50
Hope this helps!
