Answer:

10 coconut cupcakes

Step-by-step explanation: so, here is what we do since there is 8 cupcakes sold and 4 of them are coconut cupcakes we divide. this is hard to explain but we know that 8 divided by 4 is 2 so we have to multiply to 20 so like 2 times 10 which gives us 20. then we use the answer that we got from multiplying which is 10 as our answer if that makes sense.

If a varies directly as b and a=3 when b=12, what is the value of a when b=18?

Zepler [3.9K]

Answer:

a is proportional to b

a=kb

k is proportionality constant

k =a/b =3/12 =1/4

k=1/4 = a/b=a/18

What is the value of x?

Kruka [31]

Answer:

<h2>x = 3</h2>

Step-by-step explanation:

Look at the picture.

Therefore we have:

$\dfrac{4}{3}=\dfrac{x}{2.25}$ <em>cross multiply</em>

$3x=(4)(2.25)$

$3x=9$ <em>divide both sides by 3</em>

$x=3$

Solve this please with steps b^4-3b^3-10b^2

gtnhenbr [62]

Answer:

Step-by-step explanation:

There's no "solving" to be done because its an expression, but im assuming the question wants you to factor.

$b^4-3b^3-10b^2$

First, factor out a b^2

$b^2(b^2-3b-10)$

Factor the trinomial. What two numbers multiply to equal -10 but add to equal -3? They are -5 and +2

$b^2((b-5)(b+2))$
