<u>Answer:</u>
-10,1,19
<u>Step-by-step explanation:</u>
<u></u>
x+y+z = 10 (Equation 1)
2y-x= 12 (Equation 2)
x-y+2z = 7 (Equation 3)
(Equation 2): -x = -2y+12
x = 2y-12 (Equation 4)
(Equation 1) - (Equation 3): 2y-z = 3
-z = -2y+3
z = 2y-3 (Equation 5)
Substitute (4) and (5) into (1)
x+y+z = 10
(2y-12)+y+(2y-3) = 10
5y-15 = 10
5y = 5
y=1
Substitute y=1 into (2)
2y-x= 12
2(1)-x= 12
2-x= 12
-x= 12-2
-x= 10
x= -10
Substitute y=1 and x=-10 into (1)
x+y+z = 10
-10+1+z = 10
z-9 = 10
z = 10+9
z = 19
Order: x = -10, y = 1, and z = 19
Answer:
36 apples
Step-by-step explanation:
First, divide 72 by 6 to find out how many apples are in 1 basket.(Answer 12)
There will be 12 apples in one basket.
Mrs. Doolan wants 3 baskets so multiply 12 by 3 to get 36.
72/6= 12
12X3=<u>36</u>
5/3. / 35/6
5/3 * 6/35= 30/105= 6/21= 2/7. The answer to the question is b. 2/7
Range:
y >= - 3
