Answer: If you're looking for the value of x, it's 1.

Step-by-step explanation:

Add the numbers. x-10-2x+7=8+x-10-3x--->x-3-2x=8+x-10-3x

Combine like terms. x-3-2x=8+x-10-3x ---> -x-3=8+x-10-3x

Subtract the numbers.-x-3=8+x-10-3x---> -x-3=-2+x-3x

Combine like terms. -x-3=-2+-3x---> -x-3=-2-2x

Rearrange terms. -x-3=-2-2x---> -x-3=-2x-2

Hope that helps!

You gotta collect the like terms in order to simplify the answer...

So you have: 8 + x - 10 - 3x

Like terms in this are: x, - 3x ( we have a positive x and a negative 3x) remember x represents 1 so it’ll be 1 - 3x= -2x

And 8 -10= -2

Your answer is -2x - 2

Hope that helps :)

An anthropologist studies a woman's femur that was uncovered in Madagascar. To estimate the woman's height, he uses the equation
Lelu [443]

Answer:

The inequality f>40 represents the length of the femur for which the woman had a height greater than 160cm.

Step-by-step explanation:

The given equation is

h=60+2.5f

Where, h is woman's height in centimeters and f is length of the femur in centimeters.

If woman's height is greater than 160cm, then

h>160

60+2.5f>160

Substract 60 from both sides.

2.5f>100

Divide both sides by 2.5.

f>40

Therefore the inequality  f>40 represents the lengths of the femur for which the woman had a height greater than 160cm.

laila [671]
Splashtown: 25 + 1x
Schlitterbahn: 40
25 + 1x = 40
-25 -25
0 1x = 15
x = 15
So after 15 rides, Schlitterbahn would be cheaper than Splashtown.

Write a rule for the nth term of the arithmetic sequence. Then graph the first six terms of the sequence. a6=-12 a12=-36
denis-greek [22]

Answer:

We need to find the first term.  We can use the formula

an = a1 + d(n - 1)

to solve for a1.  We already know the 12th term, a12, common difference, d, and nth sequence, n.

a12 = -36

d = -4

n = 12

-36 = a1 - 4(12 - 1)

-36 = a1 - 44

8 = a1

The first term is 8.  Therefore, your formula is

an = 8 - 4(n - 1)

an = -4n + 12

Then use this formula to graph.

n is the independent variable.

an is the dependent variable.

Your graph will be a line.

n    |       an

___________

1          8

2          4

3          0

4         -4

5         -8

6         -12
