This is a very simple question, however having all the words are pretty confusing, right? Don't worry I am going to break it down. First thing you want to do is forget about how many stories are how many feet, because you are trying to find that but are probably getting very confused. So write down that the word EACH= 1-story, Then have 1-story= 15ft. so basically you add 15 to every story. 1=15, 2=30, use this to find the answers 15x= ft---> 15(10)=150ft---> do the last one. If you anymore questions I will break it down further, I used to have a hard time with these.
Answer:
-6x + 6
Step-by-step explanation:
You multiply the -6 with the other variables
In step three the prblem was incorrect. this is because you have to add four from both sides leading to 8x=20+3x then you have to subtract 3x which is 5x=20. divinding both sides by 5 is:
X=4
Answer:
7x-2, -x-6y+16, 5x-3
Step-by-step explanation:
I'm guessing the three expressions are:
1. 3(x+2) + 4(x-2)
2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
3. 2(4x+3) - 3(x+1)
... 1. 3(x+2) + 4(x-2)
= 3x + 6 + 4x - 8
= 7x - 2
... 2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
= 2x + 2y - 3x - 3y - y - 8 + 24 - 4y
= -x - 6y + 16
... 3. 2(4x+3) - 3(x+1)
= 8x + 6 - 3x - 3
= 5x - 3
Answer:
There are 800 kids in the school.
Step-by-step explanation:
Let x be the answer (how many kids are in the school).
Let's add them together. 3/5+3/8 = how many people do not bike to school, which is 0.975 of everyone. 1-0.975 = 0.025, which means 0.025x = 20. 0.025x = 1/40, so 1/40x = 20. Multiplying, we have x =800.
