Answer:
That the fractions are reduced with all common factors canceled.
Step-by-step explanation:
Hello,
Before an algebraic fraction is selected I should that the fractions are reduced with all common factors cancelled so that I got the irreducible fraction.
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
So there are 35 quarters and 21 nickels.
Step-by-step explanation:
So I guess that is all we have is quarters and nickels.
Quarters are worth .25
Nickels are worth .05
Let x represent the number of quarters
Let y represent the number of nickels
x+y=56
.25x+.05y=9.8
We are going to solve this system.
I'm going to use substitution. I will solve the first equation for y and then plug that into the second equation.
y=56-x
.25x+.05(56-x)=9.8
.25x+2.8-.05x=9.8
.20x+2.8=9.8
.2x = 7
x=7/(.2) or 7*5=35
y=56-x
y=56-35=21
So there are 35 quarters and 21 nickels.
Answer:
B. 2x + 7
Step-by-step explanation:
I can see where this is tough, lets go through it. Polynomials that are factored need to be able to multiply back into themselves. When looked at a polynomial, you can find a common multiplier for both, but we already have those. The common multipliers are what goes outside of the parenthesis. Now you just need to find what's inside. The numbers inside are going to be the numbers that multiply back to the numbers above. You can go by process of elimination to get rid of options. First, you will do 5 * 2 to get 10, meaning you can remove A and C. Then you see that you have to get to the third power on the 10, and get to x on the 4. This means you will have to have 1x on the first number of the set to ensure you get both of those numbers.
