Answer:

I think should add up to 360° because supplementary angles add up to 180°and in this case we have 2 angles

Answer:

180 degrees

Step-by-step explanation:

If two angles are supplementary when their measures add up to be 180

I attached an example of supplementary angles as well you can check

Answer:

If nobody walked on the moon, then Neil Armstrong didn't

Step-by-step explanation:

The contrapositive flips the sign of "Neil Armstrong"  and the "moon," and also switches their position, so you will switch the hypothesis and conclusion as well

Answer:

Note that the range is only the elements that were used. Yes, the relation {(3,2), (4,1), (5,9), (6,12), (7,12)}is a function. No x-value repeats.

Step-by-step explanation:

Answer: Choice A) Empty set

This is another way of saying "no solutions"

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

Explanation:

Your teacher made a typo. The given inequalities will have boundary lines that both have positive slopes, not negative slopes. So the boundary lines should go uphill as you move from left to right.

See the diagram below to see what the graph should look like.

The upper dashed line is y = (1/2)x+3. The lower dashed line is y = (1/2)x-2

The upper dashed line represents the boundary for y > (1/2)x+3. Region 1 is the set of solution points for y > (1/2)x+3

While the solution set for y < (1/2)x-2 is represented with region 3

There is no overlap between regions 1 and 3 due to the parallel boundary lines.

Put another way: there are no (x,y) points that are in both region 1 and region 3 at the same time.

So that's why there are no solutions to this system of inequalities.

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

Alternative method:

Convert the first inequality into Ax+By > C form

y > (1/2)x+3

2y > x + 6 .... multiply both sides by 2

-x+2y > 6 ... subtract x from both sides

z > 6 .... let z = -x+2y

Convert the second inequality into Ax+By < C form

y < (1/2)x-2

2y < x - 4

-x+2y < -4

z < -4 .... let z = -x+2y

We have some number z that is both z > 6 and z < -4 at the same time, but no such number exists. So this is another way to see we have an inconsistent system with no solutions.

So I did it and I got 4 it might be right might not I hope this helped.

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

a) The unknown is the price of a large pizza

b)  Each pizza cost is positive,

c) The the price of a pizza be p,

so the price of one pizza is p

d) The expression is  

6 pizzas minus 3 dollar off each pizza

6p -3p

e) Set this equal to the total cost

6p -3p= 38.94

f) Combine like terms

3p = 38.94

Divide each side by p

3p/3 = 38.94/3

p = 12.98

The price of each pizza before discount is 12.98

Answer:

study hard and find shortcuts to make it easier for you. also do not hesitate to ask teachers for help. it is their job to help

Step-by-step explanation:

Answer:

i believe your answer will be C=-2

Step-by-step explanation:

the equation is -2c + 6 = 10. to solve this youll need to subtract 6 from both sides.

-2c +6 =10

-6 -6

which will now leave you with -2c = 4. then you will divide -2 from both sides. -2/-2 =0 and 4/-2 = -2. so your answer is C=-2

Answer:

The first one 1.50 for 5oz

Step-by-step explanation:

Given :

Zach wants to make a profit of more than 300 for painting 4 identical too rooms.

The cost of supplies is 32.50 for each room.

To Find :

Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than $300.

Solution :

Profit is given by :

Profit = S.P - C.P

Now, it is given that profit > 300 .

Profit = S.P - C.P > 300

[tex]4n - 4\times 32.5 > 300\\\\n - 32.5 > 75\\\\n > \$107.5[/tex]

Hence, this is the required solution.

Step-by-step explanation:

5x - 4 versus 2x + 26

Imagine x equals 1, then the equations would be:

5(1) - 4 and 2(1) + 26

1 and 28 are not equivalent.

Another example would be x = 6

5(6) - 4 and 2(6) + 26

26 and 38 are not equivalent.

No matter what you replace x with, the expressions are never equal.

Answer:

x = 20

Step-by-step explanation:

The angles are same side interior angles so the add to 180

3x-10 + 5x+30 = 180

Combine like terms

8x +20 =180

Subtract 20 from each side

8x+20 -20 =180-20

8x = 160

Divide by 8

8x/8 =160/8

x = 20

Answer: x = 25

Step-by-step explanation:

When lines are parallel, the same side interior angles are supplementary, meaning they add up to 180 degrees. So to find x, you would add the two expressions and make it equal to 180 degrees.

3x - 10 + 5x + 30 = 180

8x - 20 = 180

8x = 200

x = 25

The answer is x=25

Answer:

Total amount earn = $31.98

Step-by-step explanation:

Given:

Cost of paper = $1.41

Cost of aluminium = $1.53

Cost of plastic = $0.33

Amount of paper = 5 pound

Amount of aluminium = 15 pound

Amount of plastic = 6 pound

Find:

Total amount earn

Computation:

Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)

Total amount earn = $7.05 + $1.98 + $22.95

Total amount earn = $31.98

Your answer will be 96.

Proof:

Step one: Subtract 14 from 30  30-14=16

Step two: Multiply the difference by 6 16x6=96

Answer:

45? this sounds like a 6th grade problem,idk sounds too easy for it to be right

Answer:

2a + 3b = 0

Step-by-step explanation:

So we are given that a = -3, b = 2, c = 5, and d = -4 and we are asked to evaluate the expression 2a + 3b. To evaluate the expression, we would have to plug in -3 for a, 2 for b, 5 for c, and -4 for d:

2a + 3b = 2(-3) + 3(2) = -6 + 6 = 0

So by evaluating the expression we get 0.

I hope you find my answer and explanation to be helpful. Happy studying.
