At the bake sale, a stray dog ate 26 of Samantha's muffins. That was 2/3 of all of them! How many muffins did she start with?

1 answer:

6 0

Let, the number of Original muffins = x

Then, x * 2/3 = 26

x = 26 * 3 / 2

x = 13 * 3

x = 39

In short,Your Answer would be: 39 muffins

Hope this helps!

Is 3 a factor of 73? ( Yes ) or ( No )

Mkey [24]

Answer:

The correct answer is no.

Step-by-step explanation:

If a number is a factor of another number, that means that it can be equally divided into it evenly.

I know that 3 x 20 = 60, and 73 - 60 = 13.

Since 3 is not a factor of 13, it is also not a factor of 73.

Hope this helps! :D

Find a value for y for which the expression (1-y)(3-y)(6-y) has each given value

erik [133]

$\\ \tt\Rrightarrow (1-y)(3-y)(6-y)=-70$

$\\ \tt\Rrightarrow -y(1+1)(3+1)(6+1)=-70$

$\\ \tt\Rrightarrow y(2)(4)(7)=70$

$\\ \tt\Rrightarrow y(56)=70$

$\\ \tt\Rrightarrow y=\dfrac{70}{56}$

$\\ \tt\Rrightarrow y=\dfrac{5}{4}$

$\\ \tt\Rrightarrow (1-y)(3-y)(6-y)=120$

$\\ \tt\Rrightarrow -y(1+1)(3+1)(6+1)=120$

$\\ \tt\Rrightarrow -y(2)(4)(7)=120$

$\\ \tt\Rrightarrow 56y=-120$

$\\ \tt\Rrightarrow y=\dfrac{-120}{56}$

$\\ \tt\Rrightarrow y=\dfrac{-15}{7}$

C^2-4c+cd-4d=(c-4)() find the missing factor

Nadya [2.5K]

It is (c+d)

you can basically use FOIL (first,outside,inside,last) to solve this.

you know the first term of the factor has to be C because of the c^2

the second then has to be D because you haven't seen D in the factor yet and it is in the equation.

then you know from the equation that the terms with D are not negative so D isn't negative so you have form the information above (c+d)
