Answer:
Problems left to complete = 9
Step-by-step explanation:
Given that:
Number of problems on the test = 45
Percent of completed problems = 80%
Number of completed problems = 
Number of completed problems = 0.8 * 45 = 36
Problems left to complete = 45 - 36
Problems left = 9
Hence,
Problems left to complete = 9
7+x, because the sum means adding.
Answer: y=2(x)-8
Explanation: (8,8) 8-4 and 8-0
- (4,0)- 4 8
- you take the 8 as the numerator and 4 and the denominator and then divide 8 by 4 to=2 which is your slope
- you pick 1 set of points (I chose (8,8) to finish the problem)
8(y-intercept)= 2(slope) • 8(x-intercept) +b
8= 16+b
-16 -16 (subtract 16 from both sides)
-8 (8-16) =b {b=-8)
-now you put together your equation,
which leaves you with { y=2(x) - 8}
^ ^
your slope your B value
Answer:
x=4/15
Step-by-step explanation:
first you need to make common denominators for 1/5 and 1/3
the common denominator is 15
5*3=15, 3*5=15. 1*3=3, 1*5=5
new equation:3x-3/15=x+5/15
now subtract x from both sides: 3x-3/15=x+5/15
-x -x
2x-3/15=5/15
now you can add 3/15 to 5/15
2x=8/15
now for the last step, divide by 2 because there are 2 x's
2x/2=x 8/15 /2=4/15
x=4/15
216/1000
Simplify it by 2
Give me a thanks if it helps!!!
