Answer:

I can help.

Step-by-step explanation:

3a is closer to 1, because 12/12 is 1. and 6/12 is 1/2

3b is closer to 0, because 0/6 is o. and 3/6 is 1/2.

3c is 1 and 1 1/12

11/12 + 1/6

find the common denominator. 12. 6×2 and 1×2 then add straight across.

How do you factor 5 out of 5x+40

VARVARA [1.3K]

Answer:

To factor something out you've got to divide, so you would take 5x+40 and divide it all by 5

So, 5x/5= 1x

And, 40/5= 8

Your answer is now x+8 when factored

Extra points!! A candle is 17 in tall after burning for 3 hours. After 5

PIT_PIT [208]

Answer:

1) $h=-t+20$

2) 12 inches tall.

Step-by-step explanation:

1) The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

In this case:

$y=h$ (The height of the candle in inches)

$x=t$ (The time in hours)

Then, we can rewrite it:

$h=mt+b$

Based on the information provided in the exercise, the line passes through these points:

$(3,17)$ and $(5,15)$

Then, we can find the slope of the line with the formula $m=\frac{y_2-y_1}{x_2-x_1}$ :

$m=\frac{15-17}{5-3}=-1$

Now we need to substitute the slope and one of the points into $h=mt+b$ and then solve for "b":

$17=(-1)(3)+b\\\\b=17+3\\\\b=20$

Substituting values, we get that the a linear equation that models the relationship between the heigth of the candle and the time, is:

$h=-t+20$

2) We must substitute $t=8$ into the linear equation $h=-t+20$ in order to find the height of the candle after burning 8 hours:

$h=-(8)+20\\\\h=12$
