Use addition to solve the linear system of equations.

3x - y = 6

y = x - 4

Answers

Answer 1

Answer:

Problem:

Solve 3x−y=6;y=x−4

Steps:

I will try to solve your system of equations.

y=x−4;3x−y=6

Step: Solvey=x−4for y:

Step: Substitutex−4foryin3x−y=6:

3x−y=6

3x−(x−4)=6

2x+4=6(Simplify both sides of the equation)

2x+4+−4=6+−4(Add -4 to both sides)

2x=2

2x

2

=

2

2

(Divide both sides by 2)

x=1

Step: Substitute1forxiny=x−4:

y=x−4

y=1−4

y=−3(Simplify both sides of the equation)

Answer:

y=−3 and x=1

Step-by-step explanation:

Hope this helped you

Well the only addition is that there should be an arrow pointing from the trout to the mayfly nymph. The first correction is that the arrow in between the trout and dragonfly nymph should be flipped because the dragonfly nymph gets eaten by the trout, not the other way around. The second correction is that since the dragonfly nymph eats the mayfly nymph, the arrow between them should also be flipped. Now you just need two explaining sentences:)

The math project scores for two different classes are shown in the box plot below.
(the picture)

Which statement about Class A and Class B math project scores is NOT supported by the graph?

A) The range of scores for both classes is 3.
B) The interquartile range for Class A is greater than the interquartile range for Class B.
C) The interquartile range for Class B is 2.
D) The median score for Class B is 0.5 greater than the median score for Class A.

Answers

Answer:

A

Step-by-step explanation:

The bar for Class A is 1.5-3.5. 3-5 - 1.5 = 2 (interquartile range)

The bar for Class B is 2-3. 3-2 = 1 (interquartile range)

Range = 2-1 = 1

Because the range does not equal to 3, we automatically know that this statement is false. But for D, the line represents the median score for each class.

how many vertices AND faces does this shape have?

Answers

Answer:

this is irregular shape it has four vertix and two faces

The number of vertices and faces this shape have is 4 and 4.

What are vertices, faces and edges?

Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).

Vertices are points of intersections of different edges.

We are given that;

The figure

Now,

Number of vertices= 3+1

=4

Number of faces= 3+1

=4

Therefore, by vertices the answer will be 4 and 4.

what is the ratio of water around in swamps to the total quantity of fresh water on the surface?

Answers

Answer:

Of the liquid surface fresh water, 87% is contained in lakes, 11% in swamps, and only 2% in rivers.

Step-by-step explanation:

The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.11

Rain and seasonal flooding cause water levels to fluctuate. In the wet soil, water-tolerant vegetation grows and helps maintain a moist, swampy condition. In many freshwater swamps in the southeastern United States, cypress and tupelo trees grow. ... Alligators, frogs, and many other animals live in these swamps.

You multiply both equations by 4 and the least common multiply of 4,2. Then 8 x 4 + 3 - 4t = 2 ( 5 x 2 +1 ) multiply 8 and 4 to get 32. Add 32 and 3 to get 35. Then you multiply 5 and 2 = 10 add 10 and 1 = 11 multiply 2 and 11 = 22 eventually ur equation should look like 35 - 4t =22 so you subtract 35 from 35 and 35 from 22 = -13 then you should have ur equation; -4t = -13 then you divide -4 by -4 = t so T = -13 /-4 but you simplify-13/-4 and switch the negative signs to positive ; 13/4

A shelf has different sizes of bottles of laundry detergent. This line plot shows the number of cups of laundry detergent in each bottle. Jada buys one of the bottles of laundry detergent that has the fewest bottles on the shelf. She uses 1/8 cup in each load of laundry she does.

How many loads of laundry can Jada do with her bottle of laundry detergent?

Enter your answer in the box.

____loads

Answers

Answer:

2 / 3 loads

Step-by-step explanation:

From. The plot, we can conclude that, the detergent that has the most bottles is that with 5 ; the number of cups in the detergent with 5 bottles is 12 cups

Number of cups used for each load of laundry = 18 cups

The loads of laundry Eric can do is thus :

Number of cups of detergent / number of cups used for each load of laundry

= 12 / 18

= 2 / 3 loads

(5^2 – 10) ÷ 5 × 2^3?
i know its 24 but can someone please explain it to me?

Answers

you have to first do parentheses so we start in there: 5^2= 25 so 25-10= 15, we next move on to exponents (which is also why we did that first in the parentheses btw) so 2^3= 8, now we’re gonna go in order since it’s all multiplication and division: 15/5=3, then 3x8=24!
Ok! So because we have to use the order of operations you have to start inside the parentheses 5^2=25 then 25-10=15 next you have to do you second set of exponents outside the parentheses 2^3= 8 now you have the equation now u just solve left to right

Antonio is in a bowling league. His goal is to score an average of at least 100 points per game. His scores so far are 105,95,97,82, and 110. How many points can Antonio score in his next game to reach his goal? Show your work.

Answers

Answer:

111

Step-by-step explanation

If he's playing 6 games to get to his goal, he needs at least 600 points

If you add 105+95+97+82+110 you get 489

So you subtract 600 from 489 and you get 111

105+95+97+82+110=489
489/5=97.8
His current average would be 97.8 per game.
You want the next games number to add to 489 and equal at least 600 (because you are going to need to divide it be 6, the number of games,)
So 600-489=
111 points
