4 is bigger, since it is a positive number.

4 is bigger because it's positive and it's on the right side of zero while -9 is on the left which makes it negative.

How many batches of raisin granola bars can Ines make if she has 8/3 cups of raisins and each batch requires 2/3 cup of raisins?

iren2701 [21]

4 batches:

2/3 • 4 = 8/3

2/3 + 2/3 + 2/3 + 2/3 = 8/3

2/3 = 0.666666666666667

0.666666666666667 • 4 = 2.666666666666667

8/3 = 2.666666666666667

Find x Thanks for the help in advance!

Marina86 [1]

I'm not sure if this is the easiest way of doing this, but it surely work.

Let the base of the triangle be AB, and let CH be the height. Just for reference, we have

$AH=2,\quad HB=6,\quad AC=x$

Moreover, let CH=y and BC=z

Now, AHC, CHB and ABC are all right triangles. If we write the pythagorean theorem for each of them, we have the following system

$\begin{cases}4+y^2=x^2\\36+y^2=z^2\\x^2+z^2=64\end{cases}$

If we solve the first two equations for y squared, we have

$y^2=x^2-4\\y^2=z^2-36$

And we can deduce

$z^2 = x^2+32$

So that the third equation becomes

$x^2+x^2+32=64 \iff 2x^2 = 32 \iff x^2=16 \iff x=4$

(we can't accept the negative root because negative lengths make no sense)

Solve the equation 3(x+4.5x ) = 36. Explain your reasoning THOROUGHLY.

Vesna [10]

Answer:

$x \approx 2.18$

Step-by-step explanation:

$3(x+4.5x)=36$

we can use the distributive property and get

$3(x)+3(4.5x)=36\\\\3x+13.5x=36\\\\$

and we can add like terms

$(3+13.5)x=36\\\\16.5x=36$

and know we divide both sides by 16.5

$16.5x*(\frac{1}{16.5})=36*(\frac{1}{16.5})\\\\x=\frac{36}{16.5}$

and doing the dvision we get that

$x\approx 2.18$
