Answer:
7x^2a
Step-by-step explanation:
7x^3a+7x^2a^2
7x^3a = 7 xxxa
7x^2a^2= 7 xxaa
The common terms are 7xxa
7x^2a
This is the greatest common factor
Yes to both, and for future help, if you find a common denominator(the bottom one) by multiplication and one is higher, boom you have your answer.
Answer:
bushels of apples were sold
Step-by-step explanation:
Let
x----> bushels of peaches
y----> bushels of apples
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y
![7(y+29)+6y=346](https://tex.z-dn.net/?f=7%28y%2B29%29%2B6y%3D346)
![7y+203+6y=346](https://tex.z-dn.net/?f=7y%2B203%2B6y%3D346)
![13y=346-203](https://tex.z-dn.net/?f=13y%3D346-203)
![13y=143](https://tex.z-dn.net/?f=13y%3D143)
![y=143/13=11](https://tex.z-dn.net/?f=y%3D143%2F13%3D11)
We can first add up the cards so we know how many we have in all:
16 + 16 + 18 = 50 cards
We can do this a little bit easier if we get the "16"-cards in one number total.
16 + 16 = 32
![\frac{32}{50}](https://tex.z-dn.net/?f=%20%5Cfrac%7B32%7D%7B50%7D%20)
= 32 x 2 =
![\frac{64}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B64%7D%7B100%7D%20)
50 x 2
![\frac{64}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B64%7D%7B100%7D%20)
= 64 : 2 = 32 %
100
We did just divide the % of two types cards on 2, so we get the %-chance of 1 type card.
I am not quite sure, but I think that 32 % is the correct answer.
