13. what is x ????????

Answer:

235

Step-by-step explanation:

325( Three digit number)

No zero

5-3=2

3+2+5=10

The house number if the house number is a three-digit number, it is a multiple of 5. There are no zeros in this number, is 235.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

A house number is a three-digit number.it is a multiple of 5,

The number in the hundreds place is two less than the number in the one's place,

The sum of the digits is 10,

Write the equation as shown below,

x + y + z = 10

Here x is in one place y is in the tens place and z is in the hundred places,

The number will be = 100z + 10y + x

y = x - 2

As we know if the number is a multiple of 5 then its one's place is either 0 or 5 here no zeroes in the number,

x = 5,

y = 5 - 2 = 3

z = 10 - 3 - 5

z = 2

Thus, the number will be,

Room number = 100 × 2 + 10 × 3 + 5

Room number = 200 + 30 + 5

Room number = 235

Answer:

y=2x-1

Step-by-step explanation:

up 2 right 1 for slope

y intercept is -1

Answer:

[tex] \boxed{(b) \: y = 2x - 1}[/tex]

Step-by-step explanation:

( 2,3 ) and ( 0, -1)

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{ - 1 - 3}{0 - 2} = \frac{ - 4}{ - 2} = 2[/tex]

Gradient is 2

y - y1 = m ( x - x1 )

y - 3 = 2 ( x - 2 )

y - 3 = 2x - 4

y = 2x - 4 + 3

[tex] \boxed{y = 2x - 1}[/tex]

Answer:

Perimeter = 30.42

Step-by-step explanation:

Using Distance Formula, √((x2-x1)^2 + (y2-y1)^2)

Find the Distance Between NO, OP, and NP

√((-3 - -3)^2 + (3 - 9)^2) - NO = 6

√((-3 - 5)^2 + (9 - -3)^2) - OP = 14.42

√((-3 - 5)^2 + (3 - -3)^2) - NP = 10

Sum All of Them = 10 + 6 + 14.42 = 30.42

Good luck on your homework/test/etc!

Answer:

First one is area of sector

Angle/360 *radius *pie squared

Secong one is the same find the area of the sector and subtract from the area of a triangle which is 2*2=4/2=2insquared

Put this in your calculator

120/360 multiply by 9 squared * pie (1)

90/360 multiply by 2 squared * pie and subtract all of that from 2 (that is the area of the triangle)

And you should get the 2 answers

SO YOU HAVE TO FIND LENGTH OF THE TRIANGLE

Step-by-step explanation:

I just answered 1.

by using the principle of similar triangles (all angles are the same between the 2 triangles, and the ratio of a corresponding pair of sides is the same for all pairs of sides) we get

AB = 2×38 = 76

AC = 2×24 = 48

WX = CB/2 = 66/2 = 33

2.

the upper small triangle and the whole big triangle are similar triangles.

and we see the ratio of the legs is 1/2 (each leg of the small triangle is half of the leg of the large triangle).

therefore,

3x = 24/2 = 12

x = 12/3 = 4

3.

AC = 16

because the height of C splits the baseline precisely in half, it means that this is at least an isoceles triangle (both legs have the same length). therefore the answer.

AC = CB = 16.

Answer:

you need picture with it

Step-by-step explanation:

Answer:

Length A:  5 ft

Width B:  4 ft

volume = 88 ft³

Step-by-step explanation:

Length A:   8 - 3 = 5 ft

Width B:   8 - 4 = 4 ft

Volume

The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).

Volume of a rectangular prism = width x length x height

Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³

Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³

Total volume = 64 + 24 = 88 ft³

Now volume of first prism

[tex]\\ \tt\hookrightarrow V=LBH[/tex]

[tex]\\ \tt\hookrightarrow V=8(2)(3)[/tex]

[tex]\\ \tt\hookrightarrow V=48ft^3[/tex]

For next prism

[tex]\\ \tt\hookrightarrow V=5(4)(2)=40ft^3[/tex]

Step-by-step explanation:

It is possible to determine if a triangle contains a right angle using Pythagoras' theorem . If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.

Answer:

y = 2x - 11

                                               Explanation:

using the formula:

[tex]\boxed{y-y1= m(x-x1)}[/tex] .........where m is slope || y1 is y value || x1 is x value

y - -3 = 2( x - 4 )

y + 3 = 2(x -4)

y + 3 = 2x - 8

y = 2x - 8 - 3

y = 2x - 11

Answer:

118

Step-by-step explanation:

LCM = 12×10 = 120

HCF = 12-10 = 2

Difference = 120-2 = 118

Kamille is wrong, because:

She needs about 8 inches ribbon not 60 inches

Answer: 25°

Step-by-step explanation: Notice that in this figure, we are given two triangles and to find the value of x, we first need to find the missing angle measure in the big triangle.

Since all the interior angles of a triangle add up to 180 degrees, we know that the missing angle of the big triangle is 180° - 94° - 41° or 45°.

Now we know all the angles of the big triangle and we know two of the angles of the smaller triangle, so we can find the value of x.

The missing angle of the smaller triangle will be 180° - 110 - 45° or 25°

So we know that the missing angle is 25°.

Answer: x= 5

Step-by-step explanation:

Plug the second equation into the first equation’s y.
3x-2(-2x+7)=21

Then use distribution

3x+4x-14=21

Add 4x and 3x

7x-14=21

Then add 14 to both sides

7x=35

Divide by 7 to get x

35/7=5

x=5

larger number=22

smaller number=16

Step-by-step explanation:

let 2x-10=larger number

let x=smaller number

x+2x-10=38

Simplify

3x-10=38

   +10  +10

Add 10 to both sides of the equation

3x=48

divide both sides by 3

x=16

First answer.

2x-10=22

2nd answer

Check your work:

16+22=38

It is correct.

Answer:

66 & -28

Step-by-step explanation:

x > y

x + y = 38

x = 10 - 2y

10 - 2y + y = 38

-y + 10 = 38

-y = 28

y = -28

x + (-28) = 38

x = 66
