Answer:
6 Nickels
42 Dimes
Step-by-step explanation:
There are 48 coins in total (nickels and dimes). Let the number of nickels be "n" and the number of dimes be "d". So we can write:
n + d = 48
or
n = 48 - d
In dollars, we know nickels are worth 0.05 and dimes are worth 0.10. In total there is $4.50, so we can write:
0.05n + 0.10d = 4.50
Now replacing first equation [n = 48 - d] into 2nd, we get and equation in "d" and solve for d first:
So, there are 42 dimes.
We know from before, n = 48 - d, so
n = 48 - 42 = 6
There are 6 nickels
When you convert from meters to centimeters, you always multiply by 100, which means that 1 meter = 1 * 100 cm = 100 cm
So, 8.6 meters = 8.6 * 100 cm = 860 cm

The solution will illustrate that the equation has one solution at x=0.
Given that adds 2 to both sides, the equation 4x = 3x results.
An algebraic equation may be described as a mathematical declaration wherein expressions are set the same as every other.
The equation is 4x=3x.
As given that add 2 on both sides, we get
4x+2=3x+2
Now, we will subtract 3x from both sides, we get
4x+2-3x=3x+2-3x
x+2=2
Further, we will subtract 2 from both sides, we get
x+2-2=2-2
x=0
Hence, When adds 2 to both sides, the equation 4x = 3x results that the equation has one solution x=0.
