Susan said, "I have four negative (blue) counters. If I double the number of counters and then share them equally with Sam, I'll have as many as I started with." Use integers to show why this is correct.

Answer:

Step-by-step explanation:

(7,-8)

is the answer

Answer:

a

Step-by-step explanation:

you add the exponents together when there are parentheses

Answer:

B

Step-by-step explanation:

When raising a number to a power, to another power, you can multiply the exponents.  Think of (6^3)^2 as (6*6*6)^2.  (6*6*6)^2 is equal to (6*6*6)*(6*6*6).  This is the same as 6^6.

Answer:

C

Step-by-step explanation:

You can use process of elimination. In D and A all the y numbers are staying the same. In B, the numbers are decreasing. So the only possible answer is C.

Answer:

200 square yards

Step-by-step explanation:

Surface area for this will be the triangle base area x 2 added to the side areas

Side areas are 11 x 5, 11 x 5, and 11 x 6 = 55 + 55 + 66 = 176 square yards

Triangle area = 1/2 (base)(height)

= 1/2(6)(4)

= 1/2(24)

= 12.

But we have two triangles, so 12 x 2 = 24.

Add the sides to the bases: 24 + 176 = 200 square yards for the surface area.

Answer:

C Base x Height ÷ 2. 300 ÷ 2 = 150. 150 ÷ 12 .5 is 12.

Answer:

A) y = [tex]\frac{11\sqrt{3} }{2}[/tex], x = 11

Step-by-step explanation:

We can use the 60 degree angle to help us solve this.

Remember: tan(angle) = opposite/adjacent

Using this formula, we get that

tan (60 degrees) = y / (11/2)

This is because y is the side opposite to the 60 degree angle and 11/2 is the side adjacent to the 60 degree angle.

Simplifying this expression, we get that

[tex]\sqrt{3}[/tex] = y/(11/2)

Multiplying both sides by 11/2, we get

[tex]\frac{11\sqrt{3} }{2}[/tex] = y

We can now use the pythagorean theorem to help us solve for x

Remember: a² + b² = c²

Since x is the hypotenuse, it is the c value. Therefore, we get:

(11/2)² + ([tex]\frac{11\sqrt{3} }{2}[/tex])² = x²

Simplifying this, we get

[tex]\frac{121}{4}[/tex] + [tex]\frac{121 * 3}{4}[/tex] = x²

Simplifying this some more, we get

484/4 = x²

121 = x²

Taking the square root of both sides, we get that

x = 11

The estimated equation of line is y = 8x+ 20

A linear equation is defined as an equation in which the highest power of the variable is always one.

Two points on the line (5, 60), (3, 44)

[tex]y- y_1= \frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

[tex]y- 60 = \frac{60-44}{5-3} (x-5)[/tex]

[tex]y- 60 = \frac{16}{2} (x-5)[/tex]

[tex]y = 8 (x-5)+ 60[/tex]

[tex]y = 8x+ 20[/tex]

Hence, the estimated equation of line is y = 8x+ 20

Answer:-0.8

Step-by-step explanation:

Answer:

fraction answer -4/5 decimal answer -0.8

Step-by-step explanation:

Step 1: Subtract 20 from both sides

Step 2: divide 5 from both sides

Step 3: check the work

5(-0.8)+20=16

5(-0.8)=-4

-4+20 = 16

Answer:

10

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

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

9^2 + (sqrt(19))^2=c^2

81+19 = c^2

100 = c^2

Take the square root of each side

sqrt(100) = sqrt(c^2)

10 = c

The hypotenuse is 10

Answer:

Step-by-step explanation:

hope this helps, have a great day/night!!

Answer:

15

Step-by-step explanation:

40=8(x - 10)

Distributive property

40 = 8x - 80

Add 80 on both side

120 = 8x

Divide both sides by 8

120/8 = 15

x = 15
