Answer: x = 3, y = 1, z = 2
<u>Step-by-step explanation:</u>
EQ 1: x - y - z = 0
EQ 3:<u> -x + 2y + z = 1 </u>
y = 1
EQ 2: 2x - 3y + 2z = 7 → 1(2x - 3y + 2z = 7) → 2x - 3y + 2z = 7
EQ 3: -x + 2y + z = 1 → -2( -x + 2y + z = 1) → <u>-2x + 4y + 2z = 2</u>
y + 4z = 9
y = 1 ⇒ 1 + 4z = 9
4z = 8
z = 2
Input y = 1 and z = 2 into one of the equations to solve for x:
EQ 1: x - y - z = 0
x - (1) - (2) = 0
x - 3 = 0
x = 3
Check:
EQ 2: 2x - 3y + 2z = 7
2(3) - 3(1) + 2(2) = 7
6 - 3 + 4 = 7
3 + 4 = 7
7 = 7 
Answer:
951.15 ltr
Step-by-step explanation:
first you convert inch into cm just to make things easier
1 inch = 2.54cm
so,
radius(r)= 24 inch = 24×2.54= 60.96cm≈ 61 cm
then calculate the volume of the sphere
i.e.
V = 4/3(πr³)= 4/3×22/7× 61³= 951158.47 cm³
Now that we have volume
we know that,
1 ltr = 1000cm³
sooo,
- x ltr= 951158.47÷1000= 951. 15 ltr

Answer:
66763
Step-by-step explanation:
47000*(1+0.105+0.17)+338+6500
I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)
Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original<span />
