You have to cross multiply
7x3=21
21 divided by 6 = 3.5 or 3 1/2
Answer:
28 inches
Step-by-step explanation:
To find the value of x you put them into an equation of: (x+6) = (3x+2), this would let you find that x=2, since 2+6 = 6+2. Once you've plugged that in all you need to do is add together all the sides, and since side A and side B are both 8 you do 12+16 to get the perimeter of 28 inches.
To do this, multiply 9 by 18. This will show you how much they all weigh if there are 18 and each is 9 pounds.
The answer is 162.
Hope this helps!
Answer:
No, the two different lines have nothing to do with eachother so the is no relationship and is not a proportional relationship.
Step-by-step explanation:
Answer:
f(8)=-31
Step-by-step explanation:
since 8 replaces x in f(x), x should be substituted as 8 in the expression. From there, after you substitute, it becomes 6(1-8)+11. Simplifying that expression is now 6(-7)+11. Multiply 6 and -7, you get -42. -42+11=-31. I hope this helps :)
