Answer:
The simplified expressions are
1) a - b + c + m + n
2) x + a + m - 2
3) m + a - k - b
4) x + a - b - c + d
Step-by-step explanation:
1) a - (b - c) + (m + n)
To simplify the above expression, we have;
a - (b - c) + (m + n) = a - b - (-c) + m + n = a - b + c + m + n
2) x + a + (m - 2)
To simplify the above expression, we have;
x + a + (m - 2) = x + a + m - 2
3) m + (a - k - b)
To simplify the above expression, we have;
m + (a - k - b) = m + a - k - b
4) x + (a - b) - (c - d) = x + a - b - c -(- d)) = x + a - b - c + d
Answer:
Step-by-step explanation:
m = 4
![y -y_{1}=m(x -x_{1})\\\\y - 4 = 4(x -[-1])\\\\y - 4 = 4(x + 1)\\\\y -5= 4x + 4\\\\y = 4x + 4 + 5\\y = 4x + 9](https://tex.z-dn.net/?f=y%20-y_%7B1%7D%3Dm%28x%20-x_%7B1%7D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20-%5B-1%5D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20%2B%201%29%5C%5C%5C%5Cy%20-5%3D%204x%20%2B%204%5C%5C%5C%5Cy%20%3D%204x%20%2B%204%20%2B%205%5C%5Cy%20%3D%204x%20%2B%209)
Answer:
The first one
Step-by-step explanation:
95\19 : 5
75\5 : 15
You will receive a free beverage and free desert on your 60th visit.
Beverage- 1, 2, 3, 4, 5, 6
Visits- 12, 24, 36 ,48 ,60
Desert- 1, 2, 3 ,4
Visits- 15, 30, 45, 60
Notice how for beverages at 60 visits you get your 6th drink for free, and for deserts, at you 60 visits you receive your 4 free desert.
So, since both numbers have the same number (60) of visits which is their common multiple between the 2, you answer is 60.
45+-17
This is the same as subtracting 17 from 45
45-17=28
