GUYS PLS HELP 45 POINTS AND BRAINLIEST FOR CORRECT ANSWER!!!!!!!!

Answer:

a=4

b=6

perimiter=38

Step-by-step explanation:

you take the side lengths by it and you can subtract and stuff then you add them all up to find the perimeter

Answer:

3-9=6 and 6-10=4

Step-by-step explanation

part of b is cut by 3 as u can see above and 9 is at the bottom on which the part is cut, as for the other one 10 is the main line and is cut by 6. so u just have minus the main line aka the long line by a parallel line next to it

Answer:

its A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:A would be the correct answer because for 1 cup   there is 1 1/2 teaspoons. For b one cup of water would have 1/4 a teaspoon of powder and same for c so the ANSWER IS A!!!

Answer:

2

Step-by-step explanation:

We have

n = 4 scores

SS = 48

For this question, we are required to find the estimated standard error

To get this, we first solve for the variance

S² = SS/n-1

= 48/4-1

= 48/3

= 16

Then S² = 16

S = √16

S = 4

Then the estimated standard error is given by:

S/√n

= 4/√4

= 4/2

= 2.

The estimated standard error is 2.

Answer: Im pretty sure its G

Step-by-step explanation:

Answer:

a=3,b=1

Step-by-step explanation:

In a parallelogram opposite sides are equal/congruent.

Using this, we know that 3a-4=a+2 and b+1=2b

1st equation:

3a-4=a+2

-a       -a

2a-4=2

   +4 +4

2a=6

a=3

2nd equation:

b+1=2b

-b     -b

b=1

a=3, b=1

Answer:

  (x, y, z) = (-1, 3, 6)

Step-by-step explanation:

The augmented matrix for the system is ...

  [tex]\left[\begin{array}{ccc|c}4&-4&4&8\\9&3&1&6\\16&4&1&2\end{array}\right][/tex]

Your graphing or scientific calculator can tell you the solution to this system is ...

  (x, y, z) = (-1, 3, 6)

__

If you want to solve this by hand, it can work well to divide the first equation by 4 to get ...

  x -y +z = 2

This can be subtracted from the other two equations to eliminate z.

  (9x +3y +z) -(x -y +z) = (6) -(2)  ⇒  8x +4y = 4

  (16x +4y +z) -(x -y +z) = (2) -(2)  ⇒  15x +5y = 0

These two equations can be reduced to standard form:

Subtracting the first equation from the second, we have ...

  (3x +y) -(2x +y) = (0) -(1)  ⇒  x = -1

Substituting into the first gives y:

  2(-1) +y = 1

  y = 3 . . . . . . . add 2

Then we can find z from the reduced first equation above:

  z = 2 -x +y = 2 -(-1) +3 = 6

Then the solution is (x, y, z) = (-1, 3, 6).

Hey there!

1. “2a + 5a”

COMBINE your LIKE TERMS

2 + 5 = 7

So this means that: 2a + 5a has to equal 7a

Answer: 7a ☑️

2. “12x – 3x”

COMBINE your LIKE TERMS

12 – 3 = 9

So that means 12x – 3x has to equal 9x

Answer: 9x ☑️

3. “3p + 2p – p”

Side note: “P” by itself is understood as 1

Equation: 3p + 2p – 1p

COMBINE your LIKE TERMS

3p + 2p – 1p

3 + 2 = 5

Which makes 3p + 2p have to equal to 5p

5 – 1 = 4

So this means that 5p – 1p has to equal to 4p

Answer: 4p ☑️

Good luck on your assignment and enjoy your day!

Answer:

Perimeter is 60.4 + 4x

Step-by-step explanation:

12.2 + 12.2 + 4(x+9)

= 24.4 + 4x + 36

= 60.4 + 4x

Answer:

2/5 • (151 + 10x )

Step-by-step explanation:

(This is going to be a long one so i apologize in advance)

First, you need to simplify the equation you're given for this particular shape by collecting terms and calculating the sums:

12.2 + x + 9 + x + 9 + 12.2 + x + 9 + x + 9

61/5 + x + 9 + x + 9 + 61/5 + x + 9 + x + 9

122/5 + 4x + 36

2/5 • (61 + 5 • 2x + 5 • 18)

2/5 • (61 + 10x + 90)

2/5 • (151 + 10x )

Answer:

Mean = 153

Median = 151.5

Mode = 159, 148, 138, 150, 165, 166, 145, 152, 155, 160, 147,

Step-by-step explanation:

Mean - add all numbers up (1820) then divide by 12

Median - put numbers in order, add two middle numbers and divide by 2

Mode - each number only came up once so they are all the mode

Answer:

x+x+64=180

2x+64=180

2x=116

x=58

Answer:

x = 10

Step-by-step explanation:

Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.

This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.

Set them equal to each other in an equation and solve for x.

Subtract 6x from both sides.

Add 8 to both sides.

Divide both sides by 2.

The value of 10 for x will make the given parallelogram a rhombus.

Answer:

B.it will move to the right.

Explanation:

We have 5 newtons of force pushing to the right, and 3 newtons of force pushing to the left. We can place the positive direction on the right hand side and the negative direction on the left.

This means we can think of "3 newtons of force to the left" as the integer -3

That way we can then add 5 to -3 getting 5+(-3) = 2. The result is positive, meaning the net force is pushing to the right. Specifically, 2 newtons of force are pushing to the right.

It's like saying there are 5 people pushing to the right and 3 pushing to the left. From each side, 3 people will pair up and they'll cancel each other out. The 2 extra people pushing right will ultimately win out.

Answer:

The answer is 122.45

Step-by-step explanation:

So basically we know that he worked 15 and 1/2 hours

He gets paid £7.90 for every hour he works

7.90  × 15 = 118.5

Then you do half of £7.90 which is £3.95 because he worked 1/2 hours half of 60 minutes is 30 minutes that why you half £7.90.

You add 118.5 + 3.95 = £122.45

and that your answer

Answer:

[tex]x = 7[/tex]

Step-by-step explanation:

Required

Determine the value of x

The diagonals of a rectangle are equal.

So:

[tex]x + 5 + 2x -2 = 3x -9+4x - 16[/tex]

[tex]x + 2x + 5 - 2 = 3x +4x - 9 - 16[/tex]

[tex]3x + 3 = 7x -25[/tex]

Collect Like terms

[tex]3x-7x=-25-3[/tex]

[tex]-4x=-28[/tex]

[tex]x = \frac{-28}{-4}[/tex]

[tex]x = 7[/tex]
