Problem
One number is eight less than five times another. If the sum of the two numbers is 28, find
the two numbers.(separate your answers using commas)
Solution
for this case we can define the following notation:
Let x and y the two numbers and we have:
x= 5y -8
and we also know that:
x+ y = 28
Replacing we got:
5y -8 +y = 28
6y = 28+8
6y= 36
And y = 6
And for x we got:
x= 5*6 -8= 30 -8 = 22
Answer:
13 dollars :D
Because if you're just ordering a cheese pizza there would be no toppings
The equation would just be 12 + 1 = 13 I believe
I think 30??
Because if there are twice as much girls then 10*2=20 girls and 10 boys. So 20+10=30
