if a=8 8=b what does b equal?
why does it equal that?

Answer:

Answer:

below, and I hope that this helps you solve it.

Step-by-step explanation:

So what you would want to do is do this.

10×10= 100 + 5×10= 50 + 3×10=30 + 5×3=15

So now you want to add, so add

100 + 50 + 30 + 15 and that would equal to 195 and now you want to divide 195 ÷ 2 and that would equal to 97.5

Answer:

140

Step-by-step explanation:

Answer:

18 centimeters.

Step-by-step explanation:

Since you already know the length (height) divide 20 by 5 = 4.

This gives you the width (4), add up all the sides ( 4 + 4 + 5 + 5).

The sum comes out to be 18.

Answer: the other silds are the same

Step-by-step explanation:

finding tenth is not necessary so

Step-by-step explanation:

solution,

given length = 3 m

breath = 10 m

and

height=6 m

Volume=l×b×h

3×10×6

180

so the volume is 180m

hope it helps you have a good day

Answer:

A) 1

Step-by-step explanation:

a triangle has 180° and a right angle has 90°

triangles have 3 angles

2 right angles would make up 180° therefore, it can only contain 1 right angle

Answer:

There can be only 1 right angle(90°) so answer A

Step-by-step explanation:

If a triangle is equal to 180 °

And each right angle is equal to 90°

Then there can be 2 or 3 becouse if it was 2 it would be a full 180° but we still need 1 more corner and if it would be 3 right angles then it would be 270 with is way farther then the capability of a triangle.

Answer:

A) 2500(1+0.03)4

Step-by-step explanation:

Answer:

Kindly check explanation

Step-by-step explanation:

Using the integer tiles :

Drawing 2 tiles each time an eagle is obtained, this gives:

-2 + - 2 + - 2 + - 2 + - 2 = - 10

Using the number line,

Each unit on the number line = - 2

Any time an eagle scored ; take a unit step to the left.

This give ls a unit step 5 times

-2 + - 2 + - 2 + - 2 + - 2 = - 10

Using direct multiplication :

-2 * 5 = - 10 as it means - 2 in 5 places ; similarly, scoring - 2 five times will give - 10

Also note :

Either - 2 * 5 or - 5 * 2 is the same due to commutativity property of multiplication

Answer:  (x, y) = (-26, 10)

This means x = -26 and y = 10 pair up together

===============================================================

How to get that answer:

Add the equations straight down. Think of having 3 separate columns for the three different like terms.

After all that, we're left with the simpler equation 3y = 30. That solves to y = 10 after dividing both sides by 3.

Plug this back into any equation involving x and y. Solve for x

3x+9y = 12

3x+9(10) = 12

3x+90 = 12

3x = 12-90

3x = -78

x = -78/3

x = -26

We have found that x = -26 and y = 10 pair up together to form the solution.

-------------------

Checking the answer:

Plug (x,y) = (-26, 10) into the first equation

3x+9y = 12

3(-26)+9(10) = 12

-78+90 = 12

12 = 12

We get a true equation since the same thing is on both sides.

Repeat the same idea for the second equation

-3x-6y = 18

-3(-26) - 6(10) = 18

78 - 60 = 18

18 = 18

The second equation is true as well.

Both equations are true, so the solution (x, y) = (-26, 10) is confirmed.

the third option, "what number, when added to negative four, is equal to negative five?"

Step-by-step explanation:

"what number, when added to negative four, is equal to negative five?" can be expressed as g + (- 4) = - 5, which is the same as in the equation.

Answer:

x = 33

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for x

x = 180 - (90 + 57) = 180 - 147 = 33

Answer:

x = 13

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = x^2

25+144 = x^2

169 = x^2

Taking the square root of each side

sqrt(169) = sqrt(x^2)

13 =x

Answer:

13

Step-by-step explanation:

[tex] \sqrt{5^{2} + 12^{2}} = \sqrt{169} \\ \\ \sqrt{169} = 13[/tex]

Answer:

  140.2°

Step-by-step explanation:

The direction of vector (x, y) is the angle arctan(y/x). The signs of the components tell you this is a 2nd quadrant angle. The arctan function only gives values in the range -π/2 to +π/2, so 180° must be added for 2nd and 3rd quadrant angles.*

  arctan(5/-6) = 180° -39.8° = 140.2° . . . . CCW from the +x axis
