Answer:
13 nickels and 8 dimes
Step-by-step explanation:
okay, we know that he has $1.45
we know $1= 100 cents.
so we know he has 145 cents
we know one nickel= $0.05
we know one dime=$0.10
we know he has twice as many minuses 3 nickels compared to dimes.
with this information we can make an equation d=dimes n= nickels
145= (5x(n-3)) + (10xd)
we know whatever we plug in for n, d will be half as much. so plug in even numbers that can easily be decided by 2 for n. then take whatever number you put for n and divide it by 2 to get d. for example, if you put 10 for n you would put 5 for d.
eventually you'll end up with an equation that looks like this
145=(5×(16-3))-(10×8)
meaning you have
16-3= 13 nickels
and. 8 dimes

If you plug in some values for x, you can graph it on the plane.
When x = 0.
When x = 1
When x = 4
Now plot the points and draw a graph through the points.
So, the last option is the answer.
Answer:
Step-by-step explanation:
you can use the pythagorean theorem. form a triangle, the distance on one side should be 6, the other 1.
The answer would be x equals 7
