You are baking brownies for your class. There are 28 total students in your class and you have baked 23 brownies. Write and solv

Answer:

2(28)=23+x

Step-by-step explanation:

There are 28 students and each student needs two brownies. You have to multiply 28 by 2 so you will have to total number on one side.

On the other you need to have the number of brownies you have at the moment and x for the number you need to bake. You want to add them because you will need to put those numbers together to get the number on the opposite side.

28x2=56 so 56=23+x. Subtract the 23 from both sides to get 33=x. x=33

To check plug 33 into x to get 2(28)=23+33. 56=23+33. 56=56

you need 33 more brownies.

So the equation would be 2(28)=23+x.

Hope that helps.

Find the value of x, given that m<PQS = 112<br><br>(ALREADY ANSWERED.)

Art [367]

We know that measure angle PQS = 112 degrees.
From the drawing, we can see that:
measure angle PQR + measure angle RQS = measure angle PQS
72 + 10x = 112
10x = 112 - 72
10x = 40
x = 4

When something increases threefold (3 times) is that 300% on the initial number?

Basile [38]

Answer:

Yes

Step-by-step explanation:

300% when converted to a fraction is 3/1 which is 3. hence, you are correct to say that

You can have a look on the ways to convert between fractions and percentage on my Instagram (learntionary) if you are interested. I do post other good tips for math there too thanks!

Answer:

Step-by-step explanation:

x months

$f(x) =\frac{x^2+64}{2x}$ 1 ≤ x ≤ 12

minimum: $f'(x) = 0$

$f'(x) = (\frac{x^{2} +64}{2x})' = \frac{(x^{2} +64)'.2x - (x^{2} +64).(2x)'}{(2x)^2}= \frac{2x.2x-(x^{2}+64).2}{4x^{2} } = \frac{4x^2 - 2x^2-64}{4x^2}=\frac{2x^2-64}{4x^2}$

$\frac{x^2-32}{2x^2} = 0 \\x^{2} -32 = 0\\x^{2} =32\\x = \sqrt{32}\\ x = 4\sqrt{2}$

$f(4\sqrt{2} ) = \frac{(4\sqrt{2})^2 +64}{2.4\sqrt{2} } = \frac{32+64}{8\sqrt{2} } = \frac{96}{8\sqrt{2} }=\frac{12}{\sqrt{2} } = 6\sqrt{2}$ ≅8.49%
