Answer:

2x-8=3x-2

2x-3x=-2+8

-1x=6

X=6/-1

X=-6

So, you want to move any number with a variable to one side and one without a variable to the other
But first, you must distribute the 2(x–4)
2(x–4) –> 2x–8
Next, move the numbers.
2x–8=3x–2
-8=x–2
-6=x
x is 6

Answers:

b = 92 degrees (choice B)

c = 92 degrees (choice D)

d = 92 degrees (choice F)

================================================

Explanation:

Angles a and b are supplementary because they form a straight angle when combined. The two angles add to 180

a+b = 180

88+b = 180 ... plug in a = 88

b = 180-88 ... subtract 88 from both sides

b = 92

------------

Angles b and c are congruent because they are alternate interior angles. Alternate interior angles are congruent when dealing with parallel lines.

Since the diagonal entrance ramps are parallel, this means the corresponding angles c and d are congruent.

Since b = 92, this means c = 92 and d = 92 also.

what is the slope of the line on the graph?​

Answers

Please post a picture than I will be glad to help

Answer:

Step-by-step explanation:

So you need to take two points off the graph. (x,y) and (x,y)

After that use those points to plug it into this equation

your gonna want to take the Y points from both and subtract from each other.

Do the same for the X points.

Y2-Y1

X2-X1

You'll then divide The Y by the X and that the Rise over Run.  When you graph that. That'll be your answer.

Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of hotdogs. How much did each package of hotdogs cost?

Answers

Answer:

hotdogs 3.45

rolls 2.60

Step-by-step explanation:

6h + 8r = 41.5

r=h-.85

6h + 8(h-.85)=41.5

6h + 8h - 6.8 = 41.5

14h = 41.5 + 6.8

14h = 48.3

h=48.3/14

h=3.45

r=3.45-.85=2.6
