Simplify:
3(x - 1) = 8x -3
Expand:
3x - 3 = 8x - 3
Cancel -3:
3x = 8x
Move all terms to one side:
3x - 8x = 0
Simplify 3x - 8 to -5x
-5x = 0
Divide both sides by -5:
x = 0
The answer is 3; Think of it as the absolute value of a number is the distance from zero
Answer:
question 67-the answer is Rory has eaten 1 1/4 of all the chocolate he has been given.
question 68-answer A-30 degrees
Step-by-step explanation:
question 67:
first Rory ate 1/2 of his chocolate
then, his sister gave him another whole chocolate bar an hour later.
that is 1/2+1=1 1/2--3/2/2=3/4
add 3/4 and 1/2--3/4 1/2~2/4--2/4+3/4=5/4 or 1 1/4
so the answer is 1 1/4
question 68:
if you draw a base to connect the last side of the angle into a triangle, you find that all three sides are equal, making the triangle an equilateral triangle. An equilateral triangle's angles all equal 30 degrees.
so, the answer is answer A: 30 degrees
