SO first off you wanna make both numbers into mix factions. 6 8/9 will be 62/9 and 2 1/2 will be 5/2. Next you wanna multiply straight across. so now the answe should be 310/18 then simply for a mixed number. you can figure that out
We will have a system of equations, and we are going to solve it by using substitution.
Let's make the equations.
x+y+z=2100
z+y=x
Since y and z are equal, I think it is easier for us to have them as one variable for now. Let the value of z and y be a.
These are the equations now.
x+2a=2100
2a=x
Since the second equation is giving the value of x, let it replace the value of x also in the first equation.
2a+2a=2100
4a=2100
2100÷4= 525
so, x and y equal 525. Let's put this in our original equation.
x+525+525=2100
x+ 1,050= 2,100
x= 1,050
So, x=1,050, y= 525 =z.
Answer:
He has 18 full sheets.
Step-by-step explanation:
44 + 52 + 67 = 163
163/9 = 18.11
The question specifically asks for a whole number, not a decimal or fraction, so the answer is 18 full sheets.
Answer:
A
Step-by-step explanation:
ƒ(x) = 2x2 + 5x – 8
g(x) = –x2 + 6x
(ƒ – g)(x)=2x2+5x-8-(-x2+6x)
=2x2+5x-8+x2-6x
=3x2-x-8
