Answer:
25
Step-by-step explanation:
Answer is: 32 nickels and 23 dimes.
<span>x - number of nickels .
y -number of dimes.
two equations in two unknowns:
1) x + y = 55
2) 0,05x + 0,1y = 3,90.
</span>nickel is a five-cent coin.
dime is a ten-cent coin.<span>
solve equation 1) for x and substitute for x in equation 2)
x = 55 - y
0,05</span>·(55 - y) + 0,1y = 3,90<span>2,75 - 0,05y + 0,1y = 3,90
0,05y = 1,15
y = 23.
x = 55 - 23 = 32.</span>
The numerical length of PR is 46
<h3>Line segment</h3>
Given the following segments
QR=2x+4
PQ = x
PR =4x -10
If Q is on line segment PR, then;
PQ + QR = PR
Substitute;
x+2x+4 = 4x - 10
3x - 4x = -10 - 4
-x = -14
x =14
PR =4x - 10
PR = 56 -10
PR =46
Hence the numerical length of PR is 46
