Answer:
Simplifying
5w = 9
Solving
5w = 9
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Divide each side by '5'.
w = 1.8
Simplifying
w = 1.8
Answer:
is the system of equations representing the situation.
Step-by-step explanation:
Given:
Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.
Now, to find the system of equations representing the situation.
<u><em>Let the number of haircuts be </em></u>
<u><em /></u>
<u><em>Let the number of hair dyes be </em></u>
<u><em /></u>
So, Alexandra can give 3 haircuts and 2 hair dyes in:
Now, giving 2 haircuts and 4 hair dyes in:
Therefore,
is the system of equations representing the situation.
We have that Options That are correct are given as
From the question we are told
Which of the following is true for this image?
a. CD is the perpendicular bisector of AB
b. Neither line segment is a perpendicular bisector.
c. AB is the perpendicular bisector of CD
d. both line segments are perpendicular bisectors.
Generally
- CD is the perpendicular bisector of AB
This is True Because CD Cuts Across AB at angle 90 in the middle
- Neither line segment is a perpendicular bisector.
This is Untrue Because CD Cuts Across AB at angle 90 in the middle
- AB is the perpendicular bisector of CD
This is True Because AB Cuts Across CD at angle 90 in the middle
- Both line segments are perpendicular bisectors.
This is True
