Answer:
x= -13
y= -28
Step-by-step explanation:
To find the two numbers, write a system of equations with x as one number and y as another:
x-y=15
5x=2y-9
Use substitution to substitute one equation into another. Then solve for the variable.
x=15+y into 5x=2y-9
becomes
5(15+y) = 2y-9
75+5y = 2y- 9
75+3y= -9
3y = -84
y= -28
To find x, substitute y= -28 into one equation.
x - (-28) = 15
x+28 =15
x = 15-28
x=-13
Answer:
let the of bag of vendors be X
3donate X bag to give 996
3×x=996
3x=996
divide both side by 3
3x\3=996\3
x=332
each vendor donated 332bags of popcorn
Answer:
It will take him 16 days
Step-by-step explanation:
If he gets $54 every 9 days then that means he get $6 a day. From that you can do 96/6 to get the answer. Hopefully that helps!
To simplify any fraction, look for a common factor in the top number
and the bottom number. If you find one, divide the top and bottom
both by their common factor. Eventually, you reach the point where
their only common factor is ' 1 ' ... that's when it's in simplest form.
4 and 10 both have 2 as a factor.
When you divide top and bottom both by 2, you have 2/5 .
This is the simplest form of 4/10 .
None of this has anything to do with mayflies. You can use the same
process to simplify fractions in ANY situation where fractions arise.
