.10d + .05n = 5.25
.10(21) + .05n = 5.25
2.1 + .05n = 5.25
.05n = 3.15
n = 3.15/.05
n = 63
Answer:
Robin will have 12 dimes in his pocket.
Step-by-step explanation:
Since;
D = One dime = $0.1
P = One penny = $0.01
Amount to have less = $1.08
From the above, when a dime is changed to a penny, the amount held by Robin will decrease by $0.09. That is,
Decease in holding = D - P = $0.1 - $0.01 = $0.09
Therefore, we have:
Number of dimes = Amount to have less / Decease in holding = $1.08 / $0.09 = 12 dimes
Therefore, Robin will have 12 dimes in his pocket.
Solution to the system of equation (-2,5)
Answer:
x=30
Step-by-step explanation:
Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.
Hope this helped!
Answer: The greatest common factor is 6.
Step-by-step explanation:
18 goes into 6, 3 times
30 goes into 6, 5 times and q2 goes into 6, 2 times
Divide all three numbers by 6.
The new equation will look like: 3x-5+2y
