Answer:
3.4 lessons per week
Step-by-step explanation:
If the teacher has to teach 6 chapter in 15 weeks, and each chapter has around 8.5 lessons. it means that the teacher has to teach in 15 weeks a total amount of lessons of 6*8.5= 51.
so 15 weeks---51 lessons
1 week------x
From the above relation we have= 51/15= 3,4 lessons per week
Answer:
not every scatter plot must contain all of those characteristics.
Since y = 2x + 14 you can substitute (2x + 14) for y in the second equation
-4x - (2x + 14) = 4.
This is an equation with only one variable so you can solve it for x. Then use that answer to find the value for y.
Distribute the subtraction sign throughout the terms in the ()s.
-4x - 2x - 14 = 4
-6x - 14 = 4 This is how I got -6x: -4x - 2x = -6x (combine like terms)
-6x -14 + 14 = 4 + 14 This will eliminate -14
-6x = 18 Now divide both sides by -6
x = -3
y = 2(-3)+14 = 8
Solution to the system is (-3, 8)

Answer:
X=4
Step-by-step explanation:
distribute the 4 to the ones in the parenthesis
-4x+28=12
move the 28 over and change the sign
-4x=-16
divide by -4
x=4
