Hi,
First calculate how much chocolate for 1 dollar.
\frac{2}{3} = 0.67 \\ 0.67 \div 5 = 0.134
Then multiply by four to get amount of chocolate for four dollars.
0.134 \times 4 = 0.536
Answer: 0.536
Hope this helps.
Answer:
Disagree
Step-by-step explanation:
You can solve this problem by doing as follows:
9x+15=3x+15
-3x -3x
=
6x+15=15
-15 -15
=
6x=0
Although x=0, x=0 is still a solution to the problem.
Answer:
A
Step-by-step explanation:
Perpendicular bisector of a line divides the line into 2 equal parts and it is perpendicular to the line.
First let's find the midpoint of CD. The point is where the perpendicular bisector will cut through the line.
midpoint= 
Thus, midpoint of CD

Gradient of line CD

The product of the gradients of perpendicular lines is -1.
gradient if perpendicular bisector(1)= -1
gradient of perpendicular bisector= -1
y=mx +c, where m is the gradient and c is the y-intercept.
y= -x +c
Subst a coordinate to find c.
<em>Since the perpendicular bisector passes through the point (8, -10):</em>
When x=8, y= -10,
-10= -8 +c
c= -10 +8
c= -2
Thus, the equation of the perpendicular bisector is y= -x -2.
