Answer:

Since both equations equal to f(x), you can set 4x+11 equal to -1 and solve for x.

4x+11=-1

Subtract 11 from both sides.

4x=-12

Divide both sides by 4.

x=-3

Eduardo has a recipe that uses 2/3 cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? How
34kurt

Answer:

4 batches: 2\frac{2}{3} cups

7 batches: 4\frac{2}{3} cups

Step-by-step explanation:

If he uses 2/3 cup of flour for <u>each</u> batch, then that is 2/3 four times, or 2/3 · 4.

\frac{2}{3} × \frac{4}{1}

= \frac{8}{3}  = 2\frac{2}{3}

If he makes three more, than that will be 7 batches in total. We can multiply 2/3 by 3 to find out how much will be needed for those extra three, then add that product to 2\frac{2}{3}.

\frac{2}{3} × \frac{3}{1}

= \frac{6}{3}  = 2

2\frac{2}{3} +2  = 4\frac{2}{3}

Thus, 2\frac{2}{3} and 4\frac{2}{3} are the answers.

hope this helps!

Which of the following options have the same value as 20% of 45 (choose 3 answer)
11Alexandr11 [23.1K]

Answer:

20% of 45 is 9,  

Step-by-step explanation:

So the answer must be 9 for an example 50% of 18 is 9  because to find 50% of something simply divide by 2 .10% of 90 is 9 because to find 10% of something divide by 10. 25% of 36 is 9 because you divide by 4 to get 25% of anything.
