In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
Since 34 only goes into 7 four times the answer is 28 with a remainder of 6:) so basically you would could by your 7s so 7, 14, 21, 28, 35 and since 35 is too much we would have to go with 28. so then we subtract 28 from 34 and that gives us 6 left over. hoped this helped:))
Equal to is the correct answer
Answer: A and C because you plug in the numbers -6 for x and -1 for y and check each one.
Hope this helps :)
Answer:
Step-by-step explanation:
If the board is 5/8 of a yard, then it is 5/8 of 36 inches (a yard is 36 inches).
5/8 * 36 = 22.5 inches.
Frank now cut's 3/5 of the length of the board. So he is going to cut off 3/5 of 22.5 inches.
(3/5) * 22.5 = 67.5 / 5 = 13.5 inches.
You don't specify what the units should be. I translate this into yards, but I think if you want something else, leave a comment.
13.5 /36 = 0.375 = 3/8 of a yard.
