Answer:
<h2>x = 4</h2><h2>JT = 18</h2>
Step-by-step explanation:
Given three points J, C and T on a line, if J is between C and T then;
CJ + JT = CT.
Given CJ=8x+5, CT=55, and JT=4x+2, substituting this parameters in the equation above will give;
SInce JT = 4x+2
I did this before and it’s the one on the left on the bottom
For this case, the first thing we must do is define variables:
x: number of nickels
y: number of dimes
z: number of quarters
We now write the system of equations:
Solving the system of equations we have:
Answer:
14 nickels
28 dimes
10 quarters
*combine like terms*
-6v-24=2v+8
*add 24 to both sides*
-6v-24+24= 2v+8+24
*simplify*
-6v=2v+32
*subtract 2v from both sides*
-6v-2v=2v+32-2v
*simplify*
-8v=32
*divide both sides by -8*
-8v/-8= 32/-8
ANSWER: v=-4
