Hey there!
3/7 is needed for 1 cake
If she needs to make 42 cakes, then multiply the amount for 1 by 42
42 × 3/7 = 126/7 = 18
She needs 18 kilograms of flour to make 42 cakes
Hope this helps :)
Answer:

Step-by-step explanation:
Due to the fact that the degree of the polynomial is odd, we know one end must go up and the other down. Because the leading coefficient is even, we know that as x approaches negative infinity, y approaches negative infinity as well. As x approaches positive infinity, y approaches positive infinity.
First, let's add all the x's.
x + x + x + x + x = 5x
5x - 1 + 1 + 1 + 1
Now, let's add together all the 1's that are being added (not the 1 that is being subtracted from 5x).
1 + 1 + 1 = 3
5x - 1 + 3
3 - 1 = 2
5x + 2
There's no way you can actually solve this unless you know the value of x; without x's value, this is as simplified as the expression is going to get.
Hope this helps!
Answer:
20
Step-by-step explanation:
You would write it as 17/3 because you times 3 by 5 and get 15 and then you add the 2 to get 17 and you leave the 3 underneath the 17 so you final answer is 17/3 and that is a improper fraction
