Answers

Answer 1

Answer:

B and D

Step-by-step explanation:

A: (5/6) x 13 = 0.883 x 13 = 10.833 which is less than 13

----> B: 4 x 13 = 52 which is greater than 13

C: (3/4) x 13 = .75 x 13 = 9.75 which is less than 13

----> D: (10/10) x 13 = 1 x 13 = 13 which is equal to 13

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

2. A and C

3. D

4. D

5. A

Answer 2

Answer:

1. B and D

2. A and C

3. 1/2 x 2,175

4. 54,811 x 2/4

5. Beth sold half the copies Rodney sold.

Step-by-step explanation:

1. 10/10 is the same as 1 so the eqaution 1 x 13 is equal to 13.

2. 1/2 is the same as saying half, so we know that will be less. 1/4 is one fourth so that will also be less.

3. Again, it will be half of 2,175 so we know that's less.

4. Still with the same theme as the other questions it will be half of 54,811.

5. Once again, 1/2 is 50% as I'm sure you know. Meaning she sold half the copies.

PLEASE let me know if that helped or didn't make sense at all.

Whats is 7 = 12v - 24?

Answers

Answer:

To the nearest tenth: v = 2.6

To the nearest hundredth: v = 2.58

Fraction form = 31/12

Step-by-step explanation:

1. Add 24 to both sides to cancel it out on the right

7 = 12v - 24

+24 +24

2. Divide each side by 12

31 = 12v

31/12 = 2.5833333

12/12 = 1v = v

v = 2.583333

It’s V=31/12

(1). 7=12v-24 (12v is a variable so you move it left hand side and change its sign)

(2). 7-12v=-24 (7 is a constant so move it to the right hand side and change its sign)

(3). -12v=-24-7 (now calculate the difference -24-7)

(4). Now it’s -12v=-31, now after that divide both sides of the equation by -12

(5). So the answer is V=31/12

I'm solving systems and I don't understand how to do it pls helpp

Answers

Answer:

Use the process of elimination. I'll only do one example since you have 4.

Step-by-step explanation:

Let's do the first question.

2x-3y=-11

2x+y=9

Our goal here is to be left with one variable to solve, this way we can use the answer for that variable to find the other. A.K.A only find X to plug into the equation to find Y. To do this, we'll use the process of elimination, in which we need to cancel out a variable.

X seems the easiest here. To cancel 2 (in the top equation), you need to have a -2. And that -2 needs to be the x coefficient in the 2nd equation, in order for us to "cancel" it out. To get -2, you multiply 2 by -1.

-1(2x+y)= -1(9)

Note that whatever you do to one side, you need to do it to both sides! Hence, why I also multiplied 9 by -1. You should now be left with:

-2x -y = -9

Now, we cancel out the positive 2 and -2 from both equations by adding the two equations.

2x-3y= 11

-2x-y=-9

X cancels out, so we're left with -4y=-20. Solve for Y, which is 5.

-4y=-20

y=5

Now that you have the Y value, plug it into any of the two equations to find your X value.

2x-3y=11

2x-3(5)=11

2x-15=11

2x=26

x=13

And voilah! Our Y value is 5, and our X value is 13.

It's pretty simple once you understand what's going on. All that we did was to cancel out one variable (either X or Y) in the two equations so that we're left with only one variable to solve. If we cancel out X, we only need to solve for Y. You do this by manipulating one of the two equations (doesn't matter which one). Once you find either X or Y, all you need to is to plug it into one of the original equations. Then, you'll have both X and Y.

And that my friend, is the process of elimination. Good luck!

Answer: 101 Degrees for angle BCD

Step-by-step explanation: All 3 angles in any triangle add up to 180, in the first triangle (one on the left), you have 58 and 78 degrees, add them both and subtract from 180, you get 44 degrees for angle C on the left. Do the same on the right side of the triangle, you should get 35 degrees for angle C on the right. Add them both up, (35+44) then subtract from 180 degrees to find the measure of angle BCD.

The first angle in a quadrilateral is 150 degrees. The second angle in the quadrilateral is 30 degrees.
The other two angles are congruent.

What are the angle measurements, in degrees, of angle 3 and angle 4?

Answer:

angle three is 30 degrees (depending on what kind of quadrilateral it is)

angle four is 150 degrees

Step-by-step explanation:

150+30

180 and if the other two are congruent meaning equal too

than they must also be 180 degrees in totale on the other side as well.

Angle is 30 degrees

Y=4x +5 y=x -4 a (3, 17) b (-3, -7) c (-3, 7) d (3, 7)

Answers

Answer:

(-3, -7)

Step-by-step explanation:

y = 4x + 5

y = x - 4

add 4 to both sides of the second equation to get y + 4 = x

plug that back into the equation to get y = 4(y + 4) +5

distribute to get y = 4y + 16 + 5

combine like terms y = 4y + 21

subtract 4y on both sides to get -3y = 21

divide both sides by -3 to get y = -7

plug -7 into the second equation to get -7 = x - 4

add 4 on both sides to get -3 = x

therefore (-3, -7)
