Answer:

Step-by-step explanation:

Because both terms are divisible by 2x. So, that's the greatest common factor. Whichever term is the greatest and can divide both the numbers it the GFC.

I need help with answering question 16 on spring board algebra 2 pg. 35 the questions says solve the system using substitution t

Jet001 [13]

Answer:

x = 147

y = 32

Step-by-step explanation:

I got a bit confused by what you said, but I think you need help being shown how to do 16, so hopefully the following will help!

So to use substitution you "plug in" the expression into each other. Here is what to do for 16!

[] First, we need to find which expression can be plugged in. The first one works! It is set equal to x, so we can easily plug it in.

[] Now, we need to set up our equation!

3y - x = -13

4y + 19 = x

3y - 4y + 19 = -13

[] Now, we solve for y and simplfy!

3y - 4y + 19 = -13

-y = -32

(I subtracted 19 for both sides and combined the y's)

Now I am going to add -y and -32 to both sides so I can have it be positive.

y = 32

[] Last, but not least, we solve for x!

- Plug the y you just solved into the equation for x

4y + 19 = x

4(32) + 19 = x

128 + 19 = x

147 = x

(hopefully this is correct, have a nice day!)

Angles α and β are the two acute angles in a right triangle. Use the relationship between sine and cosine to find the value of α

8_murik_8 [283]

Answer:

The value of angle α is 18 degree.

Step-by-step explanation:

Given information: Angles α and β are the two acute angles , α < β.

Given equation is

$\sin (2x-8)=\cos (6x-6)$

$\cos (90-(2x-8))=\cos (6x-6)$ $[\because \sin (90-x)=\cos x]$

Equating both sides.

$90-2x+8=6x-6$

$98+6=6x+2x$

$104=8x$

$13=x$

The value of x is 13.

The measure of angles is

$2x-8=2(13)-8=18$

$6x-6=6(13)-6=72$

Since 18<72, therefore the value of angle α is 18 degree.

Over [174]

Given:

Dante bought a new graduated cylinder for his chemistry class.

Volume of the cylinder = 662.7π milliliters of liquid

Converting to cubic centimeter, we get;

Volume of the cylinder = 662.7π cm³

Radius of the cylinder = 4.7 cm

We need to determine the height of the cylinder.

Height of the cylinder:

The height of the cylinder can be determined using the formula,

$V=\pi r^2 h$

Substituting the values, we have;

$662.7 \pi=\pi (4.7)^2h$

$662.7 \pi=\pi (22.09)h$

Dividing both sides by 22.09π, we get;

$30=h$

Therefore, the height of the cylinder is 30 cm.

Hence, Option C is the correct answer.
