<span>Simplifying 7b + -4 + 3b + 11 + -1b = 0
 
Reorder the terms: -4 + 11 + 7b + 3b + -1b = 0
 
Combine like terms: -4 + 11 = 7 7 + 7b + 3b + -1b = 0
 
Combine like terms: 7b + 3b = 10b 7 + 10b + -1b = 0
 
Combine like terms: 10b + -1b = 9b 7 + 9b = 0
 
Solving 7 + 9b = 0
 
Solving for variable 'b'.
 
Move all terms containing b to the left, all other terms to the right.
 
Add '-7' to each side of the equation.
7 + -7 + 9b = 0 + -7
 
Combine like terms: 7 + -7 = 0 0 + 9b = 0 + -7 9b = 0 + -7
 
Combine like terms: 0 + -7 = -7 9b = -7
 
Divide each side by '9'. b = -0.7777777778 Simplifying b = -0.7777777778</span>

Convert 213base four to base5​
kakasveta [241]

Answer:

213 in base 4 = 124 in base 5

Step-by-step explanation:

First we convert base 4 to base 10

213 in base 4

2*42 + 1*41 + 3*40

32 + 4 + 3

39 in base 10

Now we convert base 10 to base 5

39/5  

7/5  r = 4

1 r = 2

124 in base 5

Hence 213 in base 4 = 124 in base 5

You eat 2/3 of your pizza and you have 4 slices leftover. How many slices did you originally order? Write and solve an equation
avanturin [10]

Answer:

12

Step-by-step explanation:

4 × 3 = 12

3/3 = 12

2/3 = 8

1/3 = 4

8 slices were eaten and 4 are left, and if you add 8 + 4 or you multiply the 3 × 4, you get 12. There were originally 12 slices.

The point A(5.
NeX [460]

The point (6, 6) is the mid-point of A and B. Then the coordinate of the point B is (7, 5).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A (5, 7) is reflected over the point (6, 6) and its image is point B. Then the point (6, 6) is the mid-point of the A and B. Then the coordinate of the point B will be

\rm (x_2 , y_2) = (2x -x _1, 2y - y_1)\\\\(x_2 , y_2) = (2 \times 6 - 5, 2 \times 6- 7)\\\\(x_2 , y_2) = (12-5,12-7)\\\\(x_2 , y_2) = (7, 5)

More about the coordinate geometry link is given below.
