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
1.25 kg = 1250 grams
1250 : 250
÷ by 250 on both sides
5 : 1
3x = x + 8
-x -x
2x = 8
/2 /2
x = 4
since angle L and N are the same you would set the 2 sides equal to each other
I'm pretty sure the answer would be 30 people.
