Answer:
x=-1, y = 2, z = 1
Step-by-step explanation:
We are given with three equations and we are asked to find the solution to them.
2x + 2y + 3z = 5 ------------- (A)
6x + 3y + 6z = 6 --------------(B)
3x + 4y + 4z = 9 ---------------(C)
Step 1 .
multiplying equation (A) by 3 and subtracting B from the result
6x + 6y + 9z = 15
6x + 3y + 6z = 6
- - - = -
_______________
3y+3z=9
y+z=3
y=3-z ----------------- (C)
Step 2.
Substituting this value of y in equation B and C
6x + 3(3-z) + 6z = 6
6x+9-3z+6z=6
6x+3z=-3
2x+z=-1 ----------------(D)
3x + 4(3-z) + 4z = 9
3x+12-4z+4z=9
3x=-3
x=-1 ------------ (E)
Putting this value f x in (D)
2(-1)+z=-1
-2+z=-1
z=1
Now we put this value of z in equation (C)
y=3-z
y=3-1
y=2
Hence we have
x=-1, y=2 and z=1
33÷3 Because u gotta find out how many waves pass per minute 33÷3=11 now u do 11×10 because there are 10 minutes and 11 pass every minute 11×10 is 110 hope that helped
Answer:
y = -2/4x + 2 --- SLOPE INTERCEPT FORM
OR IF WANTING IT TO BE SIMPLIFIED:
y = -1/2x + 2 --- SLOPE INTERCEPT FORM
Step-by-step explanation:
The starting point is 2. The slope is -2/4 or if it needs to be simplified, then it's -1/2.
Sorry if I'm incorrect...
5/16 = 25/80
3/8 = 30/80
2/5 = 32/80
Because 25/80<30/80<32/80, the washer with the size of 5/16 inch is the smallest~
