The formula for finding the slope is:
(second y - first y)/(second x - first x)
so for this question you can say:
(6 - 4) / (2 - (-1)) = (2)/ (2+1) = 2/3 so the slope is 2/3 :)))
i hope this is helpful
have a nice day
If the puzzle was solved in 1/5 hour, we can multiply the time it took to solve one puzzle by 5.
2/5(5/1)
=10/5
=2
So she'll be able to solve 2 puzzles in one hour.

Answer:
D. 95 + 47 + 5.12 12 ÷ 4 ≠ 4 ÷ 12.
Step-by-step explanation:
(70 +30) + 72 B. 21 + (-14) + (-53) O C. 67 +1 - 18. So 12÷4≠4÷1/4 + 3/4 + 2. C. 20 + 80 + (-11)
Answer:
17
Step-by-step explanation:
(x+28y)/x =50
Multiply each side by x
(x+28y)/x *x =50*x
x+28y = 50x
Subtract x
x-x+28y = 50x-x
28y = 49x
Divide by y
28y/y = 49x/y
28 = 49 x/y
Divide by 49
28/49 = x/y
We want to find
(y+28x)/y
Rewriting as
y/y +28 (x/y)
1 + 28(x/y)
Replacing x/y with (28/49)
1 + 28(28/49)
1 +28*28/49
1+784/49
1+16
17
Answer:
3 shirts and 6 skirts
Step-by-step explanation:
lets call number of shirts x and number of skirts y
so x+y=9
17x+22y=168
multiplying the first equation by 17 we get
17x+17y=153
17x+22y=168
subtracting we get
5x= 15
x=3
and we know x+y=9 so y=6
so 3 shirts and 6 skirts
