Answer:

A- Subtract 6 from both sides of the equation.  The answer is b= 15.

For this equation, you need to do the opposite of the number in the same side of the variable. So, there is a +6. To get rid of the +6, you need to be -6.

6-6=0

21-6=15

You will be left with b on one side, and then 15 on the other side.

Answer:

D. Add 21 to both sides of the equation.

The answer is b = 198.

Check the solution by substituting 198 for b.

Step-by-step explanation:

D. 21-21= 177+21=198

     0

198-21=177

Celia filled the glasses shown below completely with water. The total amount of water that Celia poured into the glasses is 80 c
andreyandreev [35.5K]

The height of glass 1 which in cylindrical in shape is 7.6 centimeters. Since the total volume of water added by Celia is 100 cubic centimeter, and the volume of glass 2 is 26.4 cubic centimeter which is a conical in shape. Subtracting the volume of glass 2 from the total volume glass 1 can be calculated and its height.

What is the equation of this line? 12pts!
Kobotan [32]
We need to find m and b to find in the equation of a line:

y = mx + b
       ↑      <span>↑
    slope   y-intercept

To find m, the slope, we need to find the rise over the run of the line. You pick two points and use the y values finding the difference of them and do the same for the x values and put them on the bottom. Let's use the points (0, -2) and (4, 0):
    </span>↑               ↑<span>
(x₁, y₁)       (x₂, y₂)

m = (y</span>₂ - y₁)/(x₂ - x₁)
  
m = (-2 - 0)/(0 - 4)

m = (-2)/(-4)

m = 1/2

The slope is positive since the line is going upward from left to right. 

Now we need b, the y intercept, where the line intersects with the y axis, simply by looking at the graph. b is -2.

Thus, the answer is C. y = 1/2x - 2.

Find the area of the triangle that has a base of 4.2 mm and a height of 1.5 mm. 2.85 mm2 6.3 mm2 3.15 mm2 5.7 mm2
Advocard [28]

Answer: 3.15 mm²

Step-by-step explanation:

First, we multiply the height by the base: 4.2 x 1.5 = 6.3

But, since this is a triangle, we have to divide this number by 2: 6.3 / 2 = 3.15

Hope this helps you!

Evaluate the expression -(49/64)^1/2
Nuetrik [128]

The given expression is

-(\frac{49}{64} )^{1/2}

49 is the square of 7 and 64 is the square of 8.

So we can write the given expression as

-(\frac{7^2}{8^2})^{1/2}

=-(\frac{7}{8})^{2*1/2} = -\frac{7}{8}
