-- Look for all the 'a's 7a, 9a
-- Addum up 16a
-- Look for all the 'c's 6c, -15c
-- Addum up -9c
-- Write the results 16a - 9c

-2 7/10
Step-by-step explanation:
Answer:
533.3%
Step-by-step explanation:
simplify the fraction to 16/3 (3x5+1=16) then you multiply the fraction by 100
which is 533.3 or 533 1/3 %
Answer:
x=1.167 y=8
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.
7x - 6y = 48
7(0) - 6y = 48
y2 = -8 x2 = 0
(x1,y1) and (x2,y2)
(6.857,0) and (0,-8)
6.857,0) and (0,-8)
The slope of the line (m) is the steepness of the line. It is the change in the y coordinate divided by the corresponding change in the x coordinate. Simply plug in the coordinates from above and solve for m to get the slope for 7x - 6y = 48
m = (y2 - y1)/(x2 - x1)
m = (-8 - 0)/(0 - 6.857)
m = 1.167
Answer:
Step-by-step explanation:
So the table means that there are 20 1's, 120 2's, 40 3's, and 20 4's.
The total number is 20+120+40+20 = 200.
So the probability of each is:
1: 20/200 = 0.10
2: 120/200 = 0.60
3: 40/200 = 0.20
4: 20/200 = 0.10
