Answer:
1. -19x
3. 23 - 8x
5. -18x + 2y
Step-by-step explanation:
first: 3x - x = 2x
2x - 22x = -20x
-20x + x = -19x
second one:
8 - (-15) = 23
12x - 20x = -8 x
23 - 8x
third:
-10x - 8x = -18x
3y - y = 2y
-18x + 2y
Answer:
532$
Step-by-step explanation:
14% of 600 is 84 $
14% of 1200 is 168$
140 per day and there is 2 days so 140x2
add them all up and you get 532
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 3x + 1 = y OR y = - 3x + 1 ← in slope- intercept form
with slope m = - 3
Answer:

Step-by-step explanation:
Given:
Rosa has to skate around a face off circle five times.

Diameter of a circle = 9.0 m
Radius of a circle = 
Solution:
We know that the circumference of a circle.

Where;
r = Radius of a circle
Substitute
in above equation.


So, the circumference of the circle is 28.26 m.
Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.


Therefore, the distance cover by Rosa to skate 141.3 m.
