Answer:
There are 8 dimes there.
Step-by-step explanation:
This question is solved used a system of equations.
I am going to say that:
x is the number of nickels.
y is the number of dimes.
19 coins
This means that x + y = 19.
A nickel is worth $0.05. A dime is worth $0.1. The total of these coins is $1.35. So
0.05x + 0.1y = 1.35
How many dimes are there?
We have to find y.
From the first equation: x = 19 - y.
Replacing in the second:
0.05(19 - y) + 0.1y = 1.35
0.95 - 0.05y + 0.1y = 1.35
0.05y = 0.4
y = 0.4/0.05
y = 8
There are 8 dimes there.
120 is the lowest number that is divisible by 3, 5, and 8.
Answer:
x = 11 or x = -1
Step-by-step explanation:
4|x + 6| = 20
4x - 24 = 20
4x = 20 + 24
x = 44/4
x = 11
Or
4x + 24 = 20
4x = 20 - 24
x = -4 / 4
x = -1
The solution is when the two functions meet x=2. The green function is f(x), and the red is g(x).
