A baker is making cupcakes. he has 36 pounds of dough. each cupcake is made from ⅙ pound of dough. how many cupcakes can be made
Paha777 [63]

Answer: 216 cupcakes can be made

Step-by-step explanation:

<u>Given information</u>

36 pounds of dough in total

⅙ pound of dough per cupcake

<u>Set variables</u>

Let x be the number of cupcakes that could be made

<u>Set equations from given information</u>

Total = unit × number

36 = (1/6) × x

<u>Multiply 6 on both sides to isolate [x] variable</u>

36 × 6 = (1/6) × x × 6

216 = 1 × x

\boxed{x=216}

Hope this helps!! :)

Simplify. 5i−√54 Enter your answer, in simplest radical form, in the box.
Sliva [168]

Answer:

5i - 3 \sqrt{6}

Step-by-step explanation:

The given expresion is

5i -  \sqrt{54}

We need to remove the highest perfect square from the radicand.

We rewrite 54 as 6*9

This gives us:

5i -  \sqrt{9 \times 6}

This is the same as

5i -  \sqrt{9}  \times  \sqrt{6}

We now simplify to get:

5i - 3 \sqrt{6}

Graph: y = 3x - 5<br> Plz help
nexus9112 [7]

Answer:

The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move     up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!

hope this helped!
