Answer:

The degree for all triangles is 180 so

The 55 angle is the same on both sides so

55+55=110

To find x we subtract 180-110 and that equals 70

(answer=70 degrees)

Answer:

Eric is 12 and Bill is 16

Step-by-step explanation:

x= younger brothers age

x+4 = older brothers age

they are both 28 when ages are combined

x+x+4=28

2x+4=28

2x=24

x=12

Answer:

x=2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

5x - 7 = 3

    + 7     +7       -7 cancels

5x = 10

/5      /5   5 cancels and you're left with x

x  =  2

Answer:

First one-3

Second one-0

Last one-12

Step-by-step explanation:

Answer:

180

Step-by-step explanation:

Given :

the number has three digits

it is multiple of 20

hundreds digit and tens digit add to make 9

half of it is less than 100.

I suppose 180 can correctly fit into all above criterions

It is 3 digit number. 1+8 =9, 180/2 =90 which is less than 100.

Answer:

the equation in numbers looks like this: 6xK-4=2xK+4 and if you are solving this equation it is equal to 0

Step-by-step explanation:

to get to 0 you first need to cancel out the equal terms on both sides so it should look like this: 6K=2K

then you move the variable to the left hand side and change its sign so it should look like this:6K-2K=0

then you collect the like terms so it should look like this: 4K=0

and then you divide both sides by 4 and it should get you K=0

Answer:

3:2

Step-by-step explanation:

Answer:

An example would be

(x+3)-(y+12)

The two constants are 3 and 12 (I'm assuming you meant "constant" as in the number that stands by itself and not "constatant" lol)

The two variables are x and y

The two operations are addition and subtraction

In words you could say "the quantity of x plus three minus the quantity of y plus twelve"

Answer:

B. 22

Step-by-step explanation:

3 * 5 + 5 * 3 = (2 * 3 - 3 * 5 + 3 * 5) + ( 2 * 5 - 3 * 3 + 5 * 3)

                   = (6 + 10 - 9 + 15) = 22.

Answer:

B. 22

Step-by-step explanation:

Answer:

XZ = 2.5 BD

Step-by-step explanation:

Comparing the two triangles,

[tex]\frac{BD}{BC}[/tex] = [tex]\frac{XZ}{XY}[/tex]

[tex]\frac{6}{8}[/tex] = [tex]\frac{XZ}{20}[/tex]

⇒ XZ = [tex]\frac{20*6}{8}[/tex]

         = 15

XZ = 15

So that,

BD:XZ = 6:15

           = 1:2.5

Therefore, the relationship between BD and XZ is XZ = 2.5 BD.

Answer: 7

Step-by-step explanation:

7x1x1=7/1=7

Answer: 1/20 (fraction) or 0.05 (decimal)

Step-by-step explanation:

first i like to make them a decimal so its easier.

1/4 = 0.25

1/5 = 0.2

multiply 0.25 and 0.2 = 0.05

make 0.05 a fraction

1/20

simplify. (it's already in its simplest form)

the answer is 1/20 as a fraction or 0.05 as a decimal.

(i dont know which one ur teacher wants u to do fraction or decimal?)

Answer:

first answer

Step-by-step explanation:

Answer:

The correct approach is Option A (-4).

Step-by-step explanation:

The given values are:

Vertex of the parabola,

(h, k) = (3, 5)

Passing through,

(x, y) = (-1, 6)

As we know,

The equation of parabola is:

⇒  [tex]x=a(y-k)^2+h[/tex]

On substituting the given values in the above equation, we get

⇒  [tex]-1=a(6-5)^2+3[/tex]

⇒  [tex]-1=a+3[/tex]

On substracting "3" from both sides, we get

⇒  [tex]-1-3=a+3-3[/tex]

⇒           [tex]a=-4[/tex] (coefficient of squared term)

Thus the above is the right choice.

Answer:

the equation will be  2(6x+10+4x+1)

simplified to

12x+20+8x+2

simplified to

20x+22

The perimeter of the rectangle will be 20x+22

Thank you, Hope it helps

Answer: The length of both sides would be 12x+20 and the width of both sides would be 8x+2, so the perimeter of the rectangle would be 20x+22

Answer:

w = width

h = height

2(w+h) < 200

w + h < 100

since w = 36, then

36 + h < 100

h < 100 - 36

h < 64

Step-by-step explanation:

The perimeter of the rectangular picture frame can be calculated by the equation,

                                 2h + 2w = P

where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,

                                2h + 2(36 in) < 200

The inequality gives h as,

                                          h < 64

Thus, the answer is letter A.
