I really need help. Giving brainliest to the real answer. Please my grade closes tomorrow (don’t mind the writing I tried doing it myself)

Answer:

D

Step-by-step explanation:

You add the "columns."  The equations are arranged so that like terms are stacked vertically.  3x and 7x are like terms; when you add them, you get 10x.

-y and y are like terms; when you add them, you get 0 (that doesn't appear in the sum).

-5 and 15 are like terms; add them to get 10.

The sum of the two equations is the equation 10x = 10.

Answer:

10 pounds on planet earth which turns very slowly

Step-by-step explanation:

Explanation:

The given equation is the same as y = 0x - 7. It matches the form y = mx+b which is slope intercept form of a linear equation.

The slope m = 0 always applies to horizontal lines. All points on this line have a y coordinate of -7.

Answer:

40%

Step-by-step explanation:

The ratio is 20:50, we can expand to 40:100, so 40%

Answer:

x=2, y=6

Step-by-step explanation:

Answer:

27pi in^3

Step-by-step explanation:

the volume for a cone is (1/3)pi*r^2*h. r=3in, h=9in. so the volume is (1/3)*pi*3^2*9=27pi

Answer:

f(-4) = -6

g(2) = -14

Step-by-step explanation:

To evaluate a function we must plug in the values of x. So for:

f(x) = 2x+2

we have:

f(-4) = 2(-4)+2

then we simplify:

f(-4) = -8+2

so f(-4) = -6

Now the same steps are taken for g(x) in which the answer would be -14.

Answer:

they are technically congruent due to same angles n same or equal sides

Answer:

Step-by-step explanation:

Two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.

so your amswer is A. True

Answer:

28

Step-by-step explanation:

24-10=14

14x2=28

Answer:

willaim had 28 comic books to begin with

Step-by-step explanation:

So we can take 24-10=  to see how many comics he had before his total of 24  which :

24-10=14

Then we want to find how many he had in the beging so to reverse division we would use multiplication so we would do 14x2=  because a half x a half will equal a whole :

14x2=28

So therefor William started of with 28 comic books

Answer:

120

Step-by-step explanation:

If you graph out the two triangles, you can see that the rotation is close to an angle of 90 - 120 degrees. And the rotation is going counterclockwise into the positives (graph quadrant IV).

Answer:

y = - 5x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 5 , then

y = - 5x + c ← is the partial equation

To find c substitute (- 2, 6 ) into the partial equation

6 = 10 + c ⇒ c = 6 - 10 = - 4

y = - 5x - 4 ← equation of line

Answer:

They bought 20 plants

Step-by-step explanation:

If you minus the total 750- 250 of potting supplies it leaves you with 500.

Divide 500/ 25 = 20

Answer:

20 plants

Step-by-step explanation:

500 divided by 25 = 20

The slope at the line would be the 360 point turn.

Step-by-step explanation:

B will equal 20.87 degrees

C will equal 42.1 degrees

c will equal 26.3

Answer:

The answer is c

Answer:

61.3737378

Step-by-step explanation:

First find the ten millionth digit, and the digit after it.

The digit "8", the seventh digit to the right of the decimal point is the ten millionth digit.

As the digit after "8" is 4, which is less than 5, so simply round the digit "4" down.

Thus the answer is 61.3737378

Rewrite 133% as a decimal by dividing by 100:

133% = 1.33

Now multiply:

200 x 1.33 = 266

Answer: 266

133% of 200 = 266

133 of 200 can be written as:

133/200

To find a percentage, we need to find an equivalent fraction with the denominator 100. Multiply both numerator & denominator by 100

Multiply both numerator & denominator by 100 Therefore, the answer is 66.5%If you are using a calculator, simply enter 133÷200×100 which will give you 66.5 as the answer and as we know 66.5 is also known as 226.

Answer:

The answer would be 124.4

Step-by-step explanation:

The simple answer is 124.4 lb on the moon it would way the explation behind this is that the moons gravity is 1.62m/s so dividing that by 1.62 it would be 12.4.4 lb but because of the moons twist on it's axes would make it 90 Ib

Hope this helps :)

Answer:

[tex]138[/tex] miles in 6 days

Step-by-step explanation:

Our [tex]Rate[/tex] is [tex]23[/tex] miles per day.

Rate in Math - The speed of something happening in a certain amount of time, it is usually consistent.

Rate in Physics - Rate means rate of change. Basically, how much a certain quantity changes with respect to another quantity that is also changing. You may also sometimes hear the term gradient which describes the same thing.

To find how many miles she will run in 6 days we will multiply our [tex]Rate[/tex] by our Time, to find our distance, [tex](Miles, Physics)[/tex]

[tex]23\cdot6[/tex]

[tex]138[/tex] miles in 6 days
