<span>1) Solve for x:
2x=12
divide both sides by 2
2x/2 = 12/2
x = 6

2) If x=10, what is x+2x+7?

</span>10 + 2(10) + 7 = 10 + 20 + 7 = 37

<span>3) A petting zoo always brings 5 goats to a birthday party. They also bring two chickens per guest. If there are 20 guests, how many animals in total will be brought?

</span>two chickens per guest and there are 20 guests
so 2 x 20 = 40 (40 chicken for 20 guests)

40 chicken + 5 goats = 45 animals

answer
45 animals in total

1) if 2x=12
so x=12/2
=6
2) if x=10
then x+2x+7
=10+(2×10)+7
=10+20+7
=37
3) it will be
5+(2×20)
=5+40
=45

Can someone tell me what is 8/9+3/5

I am Lyosha [343]

Okay I am going to explain to you and show you how to get the correct answer.

Fist you need to find the Greatest common factor which is 45 because 5×9=45

8/9=40/45

+3/5=27/45
__________
67/45 is reduced to 1 22/45
5 goes into 45 9 times so 3 times 7 equals 27 and 9 goes into 45 5 times so 8 times 5 equals 40 you add both numbers up and get 67. 67 can't go into 45 so you subtract 67 from 45. 45 goes into 67 1 time so that is your whole the number. 22 is left over so that is your numerator. The denominator remains the same.
