Answer:
x = 6
Step-by-step explanation:
Given
3x - 11 = - 2x + 19 ( add 2x to both sides )
5x - 11 = 19 ( add 11 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Answer:

the answer is 40$
These are 3 questions and 3 answers.
1) Question 18
Answer: 3
Explanation:
i) Equation given: 3x - y = - 4
ii) Transform to slope-intercept form: y = mx + b, where m is the slope.
y = 3x + 4
iii) Then, the slope is m = 3.
2) Question 19
Answer:
17 horizontal layers
43 bricks are left
Explanation:
i) Data:
number of bricks: 5500
number of bricks per horizontal layer: 321
ii) Calculations:
Divide the number of bricks by the number of bricks per horizontal layer: you need both the quotient and the remainder.
5500 ÷ 321 = 17 and 43 are left.
3) Question 20
Answer: indefinite
Explanation:
The line is vertical.
All the vertical lines have indefinite slopes.
That is because the slope is given by:
slope = change in y / change in x.
But x is constant, which means that the change in x is zero. And, since the division by zero is not defined, the slope is not indefinite.
