Answer:

1st one:

37 - 25 = 12

2nd one (to the right of the one on the top-left):

(19 - 10) - 7 = 2

3rd one (below the one of the top-left):

Since BD = 13 and CD = 10, BC must equal 3.

AC would equal the sum of 8 and 3.

8 + 3 = AC

11 = AC

4th one:

Not exactly sure what you want to find here, add more info.

But if you want to find the middle or mid-point:

10 + 3x + 5 = 25

15 + 3x = 25

3x = 10

Divide by 3 on both sides:

x = 3.33 or 31/3 or 10/3

5th one (bottom-left):

*First find x*

9 + x + 2x - 3 = 30

6 + 3x = 30

3x = 24

Divide both sides by 3:

x = 8

*Now that you have x, you can find the length of DE:

2(8) - 3 = DE

16 - 3 = DE

13 = DE

What is the answer to this somebody!!!

Use the geometric mean for right triangles as the sides are related to the hypotenuse. 30 - 6 = 24. We need that for our proportion. $\frac{24}{x}=\frac{x}{30}$ . We cross-multiply to get $x^2=720$ . Taking the square root of both sides gives us that $x=12\sqrt{5}$ , the second choice above.

Hudson has a balance of -$12.50 in his bank account. Daniel has a balance of $6.25 in his bank account. Use absolute value to fi

nasty-shy [4]

Answer:

The absalute value is $6.25 because $12.50-$6.25=$6.25 and thats how much daniel has in his bank account.

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:

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

Graph the equation <br><br> y≥-4/3x-7

True [87]

Answer: See picture

Step-by-step explanation:

For this problem, we need to know how to graph the inequality. First, let's establish that we will have a solid line because the inequality is greater than or equal to. If the inequality was only greater than, then it would be a dotted line. For -4/3x-7, you would start at (0,-7) as the y-intercept. Then you would go down by 4 and go to the right by 3 units. Now, we have to do shading. Since we know that y is greater than or equal to, the shading will be on top of the line, where y is greater.
