x=5,11

y=8,8,11

Answer:

Answer:

No, it does not.

Step-by-step explanation:

As if we attempted to solve for x, 5x & 5x will both cross each other out. There are no values of x that make the equation true.

1.

Step 1: Flip the equation.

p=2w+21

Answer:

p=2w+21

2.

Step 1: Add -b to both sides.

Step 2: Divide both sides by 2.

Answer:

a= −1 /2b+1/2 c

3.

Step 1: Add 2a to both sides.

−2a+b+2a=c+2a

b=2a+c

Answer:

b=2a+c

Answer:

We know that each cube with a -inch edge length has a volume of cubic inch, because . Since the prism is built using 24 of these cubes, its volume, in cubic inches, would then be , or 3 cubic inches.

Step-by-step explanation:

Answer:

y=2x+10

Step-by-step explanation:

In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.

In this case it is y=2x+3

All parallel lines have the same gradient. The gradient of this line = 2.

If the line crosses the x axis at x=-5, then when x =-5 y = 0.

If you put all this in the form y =ax + b you get 0 = 2(-5) +b

So all you need to do to find b is rearrange. b = 10.

Therefore your line has gradient 2 and y intercept 10.

y = 2x + 10

Step-by-step explanation:

In a parallelogram AO and OC are equal. Therefore you should set up the equation 3x-4=8. When you add 4 to both sides you get 3x=12. When you divide both sides by 3 you get x=4

Answer:

45.6° (1 d.p)

Step-by-step explanation:

Using the cosine rule;

c = √( a² + b² - 2ab Cosx)

11 =√(8² + 15² - 2 (8) (15) Cosx)

11² = 8² + 15² - 240 Cosx

11² - 8² - 15² = - 240 Cosx

-168 = -240 cosx

cosx = 0.7

x = cos⁻¹ (0.7) = 45.57 ≈ 45.6°

Answer: 2 11/24

Step-by-step explanation:

How many hours does the plane save?

Time taken for the train = 5 1/8

Time taken for the plane = 2 2/3

The number of hours saved will then be:

= 5 1/8 - 2 2/3

Let the lowest common multiple be 24

= 5 3/24 - 2 16/24

= 2 11/24

The number of hours saved by the plane will be 2 11/24

That would be 194 my friend!

Step-by-step explanation:

the answer is 4

x=2 and the hypotonouse is equal to 2x

Answer:

x = 2

Explanation:

according to BPT theorem,

BD BE

---- = ----

DA EC

6 x+1

--- = ----

4 x

6x = 4x +4 ( cross multiplication)

transposing,

6x -4x=4

2x= 4

x= 2

hence x=2

BE = x+1 =2+1 =3

EC = x =2

Answer:

Perimeter of triangle PQR = 181.5 mm

Step-by-step explanation:

Midsegment theorem states that,

"Midsegment connecting the midpoints of the two sides of a triangle is parallel and half of the length of the third side"

From the figure attached,

PQ = [tex]\frac{1}{2}(EF)[/tex]

     = [tex]\frac{83}{2}[/tex]

     = 41.5 mm

PR = [tex]\frac{1}{2}(GF)[/tex]

     = [tex]\frac{110}{2}[/tex]

     = 55 mm

QR = [tex]\frac{1}{2}(GE)[/tex]

      = [tex]\frac{170}{2}[/tex]

      = 85 mm

Perimeter of triangle PQR = PQ + QR + PR

                                           = 41.5 + 55 + 85

                                           = 181.5 mm  

Answer:

b=1

Step-by-step explanation:

2b+1+2b=3b+2b

4b+1=5b(Simplify both sides of the equation)

4b+1−5b=5b−5b(Subtract 5b from both sides)

−b+1=0

−b+1−1=0−1(Subtract 1 from both sides)

−b=−1

−b

−1

=

−1

−1

(Divide both sides by -1)

b=1

Next is Neither

And the first one was C

On Edgenu ity

Answer:

The answer is AAS.

Step-by-step explanation:

Since you have 2 angles that are the same and 1 side which are the same or congruent.

A = E

and C=C they are vertical angles so they are the same

And the AB and ED  side are also same.

Answer:

x = 6

Step-by-step explanation:

AC = 5x - 24

AO = 3

AC and BD bisect each other at point O. This means AC ≅ CO.

So, 2(AO) = AC.

2(3) = 5x - 24

Multiply.

6 = 5x - 24

Combine the constants.

30 = 5x

Divide by 5.

x = 6
