Multiply 20 and 9 to get 180.

180 x 2 x 2

Multiply 180 and 2 to get 360.

360 x 2

Multiply 360 and 2 to get 720.

= 720

Answer:

5 and 8 are supplementary

3=8 (vertically opposite)

so 5 and 3 are supplementary

also 5 and 6 are supplementary (linear pair)

now we've got

5+3=180°

5+6=180°

3=6

Statement: 5 and 3 are supplementary as 3=8

reason: vertically opposite

statement: 5 and 6 are supplementary

reason: linear pair

statement: 3=6

reason: both are supplementary to a same angle

Congruence means they are identical. From the markings, two angles are the same and one side is the same. So angle-angle-side.

Answer:

48 units squared

Step-by-step explanation:

You can find the number of squares in each sector by multiplying by the width and height.

So we have 4 boxes that have 10 squares each giving us 40 squares for the 4 boxes plus the other 2 boxes that have 4 squares each.

4 * 10 + 2 * 4 = 48

We get 48 inches squared.

Answer:

x=12

Step-by-step explanation:

you take 5x+5+115=180 and you get 5x+120=180 you subtract 120 over to get 5x=60 then divide by 5

Answer:

Step-by-step explanation:

When you take the square root of a number, you want the number inside of the square root to be a positive sign since we can't take the square root of a negative.

So, what would make the [tex]\sqrt{x+y}[/tex] a positive?

(x+y) > 0

For each individual one, (Note: [tex]\sqrt{x+y} \neq \sqrt{x} +\sqrt{y}[/tex]

What would make [tex]\sqrt{x}[/tex] positive?

x > 0

What would make [tex]\sqrt{y}[/tex] positive?

y > 0

Answer:

y+5 = 1/4(x+7)

Step-by-step explanation:

Point slope form is

(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y- -5 = 1/4(x - -7)

y+5 = 1/4(x+7)

Hello There!

Point-Slope:

y-y₁=m(x-x₁)

y-(-5)=1/4(x-(-7)

y+5=1/4(x+7)

y=1/4x+1.75+5

y=1.4x+6.75

Hope this helps!

your answer is going to be 100 and how you do that is you're going to estimate which means you're taking an educated guess and is it 70 closer to zero or 100 70 is only 20 numbers away and how you find that is by subtracting 100 from 70 which equals 20 and how you do that to see if it's up or down is 50 is in your middle okay so it's going to go from 0 to 50 to 100 on a number line 70 is in between 50 and 100 so that means that you'll be going up now if you did 30 instead of 70 in your equation rounding by 10 then it would be in between the zero and the 50 which that means that you're going down

The x- intercept is the value of x, when y = 0:

The y- intercept is the value of y, when x = 0:

x intercept

(2.5,0)

y intercept

(0,-5)

The question illustrates linear equation

The given parameters are:

[tex]\mathbf{m = \frac 35}[/tex] --- the slope

[tex]\mathbf{(x_1,y_1) = (6,1)}[/tex] -- the point it passes through

(a) The equation in point slope form

This is represented as:

[tex]\mathbf{ y - y_1 = m(x - x_1)}[/tex]

Substitute known values

[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

So, the equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

(a) The equation in slope intercept form

In (a), we have:

[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

Open brackets

[tex]\mathbf{ y - 1 = \frac 35x - \frac{18}5}[/tex]

Add 1 to both sides

[tex]\mathbf{ y = \frac 35x - \frac{18}5 + 1}[/tex]

Take LCM

[tex]\mathbf{ y = \frac 35x + \frac{-18 + 5}5}[/tex]

[tex]\mathbf{ y = \frac 35x + \frac{-13}5}[/tex]

[tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

Hence, the equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

Answer:

6^6 = 6^2 x 6^4 = 46656

Step-by-step explanation:

6^16/6^2 = 78364164096 so doesn't equal 6^6

(6^2)^8 / 6^4 = 1679616 so doesn't equal 6^6

(6^4)^2 = 1679616 so doesn't equal 6^6

6^-1 x 6^9 = 1679616 so doesn't equal 6^6

6^-1 x 6^-8 = 9.92 so doesn't equal 6^6

Answer:

Yes

Step-by-step explanation:

2x³-0x²+1x is similar to 2x³+1x

because if we simplify both equations we get...

2x³-0x²+1x simplified= 2x³+x

and...

2x³+1x simplified = 2x³+x

therefore we get the same answer for both

thus they're similar

Answer:

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.

Step-by-step explanation:

Before we come up with an equation we can solve the problem and see how we solved it. If Aaron had 1,276 pics and his sister took 4 times that, we would multiply 1,276 by 4 to get how many his sister took. We don't need to do the math, but that's how we would solve it. So to find p, or Ashely's amount of pics, it's just 1,276 times 4 = p

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.

Answer:

3.75

Step-by-step explanation:

Angle 2 and angle 3 are supplementary angles, so we can add them together and put it equal to 180°

Equation:

30x + 14 + 10x + 16 = 180

Combine like terms:

40x + 30 = 180

Subtract 30 from both sides:

40x = 150

Divide both sides by 40:

3.75

Check:

Take the orginal equation:

30x + 14 + 10x + 16 = 180

Plug in for x:

30(3.75) + 14 + 10(3.75) + 16 = 180

Solve:

112.5 + 14 + 37.5 + 16 = 180

180 = 180 ✅

b. Complementary gas masks

Step-by-step explanation:

Adjacent means that the two angles are right next to each other and touching. The two angels in the photo are touching. Supplementary means that the two angels can for together to make a 180 degree line. The two angels in the photo make a 180 degree line. Complementary means that the two angels make a 90 degree angel. Since the two angels already make a 180 degree angels then, they cannot make a 90 degree angel. The question is asking for what it is not so, complements would be the answer.
