If B is the midpoint of AC, and AC = 8x-20, find BC

Sounds like you want to find f(4) when f(x) = 6x+5

If so, then

f(x) = 6x+5

f(4) = 6(4)+5 ... replace x with 4

f(4) = 24+5

f(4) = 29

Answer:

The answer would be x= -1

Answer:

Step-by-step explanation:

-1.3 + 1.9 = 0.6

Answer:

4.  770 people

5.  16 min

6.  10.8 laps

Step-by-step explanation:

4.  330 people   =       x        

      3 hours               7 hours

just cross multiply:

3x = 330(7)

x = 2310 / 3

x = 770 people

5.   15 laps =   30 laps

        8                x

just cross multiply:

15x = 30(8)

x = 240 / 15

x = 16 mins

6.   18 laps =       x      

        10              6

just cross multiply:

10x = 18(6)

x = 108 / 10

x = 10.8 laps

Answer:

46

Step-by-step explanation:

Answer:

24 candy bars

Step-by-step explanation:

1case=6boxes of candy bars

1 case=144 candy bars

1 box has the same number of candy bars as the rest

What is the number of candy bars in 1 box

6 boxes = 144 candy bars

1 box = ?

144×1 ÷6= 24 candy bars

1 box has 24 candy bars

Answer:

The answer is "-9 feet and Ground-level".

Step-by-step explanation:

Given value:

total length or distance from apple tree = 9 feets

In the calculation of the distance between both the ground and the tree will be the same.  

If he gets higher 9 feet, he will go back to the ground 9 feet, in this case, the represents ground  value is equal to 0.

In the calculation of absolute values it value is opposite but the same.

Your question has been heard loud and clear.

3[-x + (2 x + 1)] = X – 1

= 3[-x+2x+1]= x-1

= 3 [ x+1] = x-1

= 3x+ 3 = x-1

3x-x = -3-1

2x= -4

so , x = -4/2 = -2

Therefore , x = -2

Thank you

Answer:

3x+3=x-1

3x-x=-1-3

2x=-4

x=-2

Answer:

[tex]KM = 4[/tex]

Step-by-step explanation:

Given

[tex]LM = 3x + 3[/tex]

[tex]KM = 5x + 4[/tex]

[tex]KL = 5x + 1[/tex]

Required

Determine KM

The relationship between the given parameters is:

[tex]KM = KL + LM[/tex]

Substitute the values of KM, KL and LM

[tex]5x + 4 = 5x + 1 + 3x + 3[/tex]

Collect Like Terms

[tex]5x - 5x - 3x = 1 + 3 - 4[/tex]

[tex]-3x = 0[/tex]

Divide through by -3

[tex]x = 0[/tex]

Substitute 0 for x in [tex]KM = 5x + 4[/tex]

[tex]KM = 5 *0 + 4[/tex]

[tex]KM = 0 + 4[/tex]

[tex]KM = 4[/tex]

3.7×1.2=3+0.7+0.6+0.14=4.44

Step-by-step explanation:

I added all the choices together I picked the one that had the same answer. Good luck!

Owen's model is represented by -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

Given is that Owen creates this model to determine the product of two decimals.

The equation that represents the Owen's model is -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

Therefore, Owen's model is represented by -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

Step-by-step explanation:

We can simply use a graphing calculator to graph the function

[tex]\boxed{y-3 = -(x+10)}[/tex]

See in the attached file!

Answer:

I believe it has now been simplified fo easy conclusion

That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.

If you had 2a+3a, then it would simplify to 5a

Similarly, 2b+3b = 5b

Or you could have 2ab+3ab = 5ab

The key is that the variable portions must match up to be able to add them.

Answer:

He can buy 22 lunches.

Step-by-step explanation:

To find how many he can buy if he had $100, we must divide the cost of one lunch to the amount of money he has.

(Round to the nearest whole number to get the exact amount of lunches that he can buy.)

1 lunch = $4.50

So:

=$100 ÷ $4.50 = 22.222....

=22.222.... = 22

Hope this helps! I'm sorry if it's wrong.

Answer:

Smaller Number=4, Larger Number=11

Step-by-step explanation:

I just guessed and checked

y = 3 is written in slope-intercept form (y = mx + b).

The only variable we are given in this equation is "b" which is "3".

We don't have a slope variable at all which means the slope is 0 or undefined.

The y-intercept is 3.

Best of Luck!
