Find 20% of 45.80
0.20 * 45.8 = 9.16
So they should leave $9.16 for the tip.
The value of x is -2 and the value of y is -1.
Step-by-step explanation:
Step 1; The given equations are taken as
-3y -9x =21 or -9x -3y = 21, take this as equation 1
-18x +4y =32, take this as equation 2
Step 2; We multiply equation 1 with 2 and equation 2 with 1 so we can cancel out the variable x in both equations. By doing this we get
-18x -6y =42, take this as equation 3
-18x +4y =32, this is the same as equation 2
If we subtract 3 with 2, we cancel out the x variable and can calculate the value of y.
10y = -10 , y = -10/10 = -1
Step 3; Substituting this value of y in any of the previous equations we will get x's value. Here this value of y is substituted in equation 2.
-18x +4(-1) =32, -18x -4 = 32 , -18x = 36, x=-2.
So we have x = -2 and y = -1.
It depends on what you get if are ranked low you will need help with the skill and if rank average you just are in normal classes and if you are ranked above average you probably are either left in the average class or go to advance math.
Answer:
12 days
Step-by-step explanation:
You should find the least common multiple of the two numbers
3, 6, 9, 12, 15, 18
4, 8, 12, 16, 20
The least common multiple is 12, so they work on the same day 12 days from now.
