Alexus [3.1K]

we have the following:

Let the number of solid ticket of cost:

x = upper level

y = center court

z = floor seats

\begin{gathered} z=9x \\ x=55+y+z \\ 30x+51y+76z=95215 \end{gathered}

therefore:

Nick is now seven times as old as harry. In 6 years , nick will be five times as old as harry. How old will harry be in 6 years?
gizmo_the_mogwai [7]
X = Harry's Age

Nick's age is 7x 

In 6 years Harry is 7x+6, and Nick is 5(x+6)

7x+6=5x+30

2x+6=30

2x = 24

x = 12

Harry = 12 years old and in 6 years Harry will be 18.

Let z1 = a1 + b1i, z2 = a2 + b2i, and z3 = a3 + b3i. Prove the folowing using algebra or by showing with vectors.
Svetlanka [38]

Answer:

a)z1 +z2 =z2 + z1 ...proved.

b) z1 + ( z2+ z3 )=(z1+z2)+z3 ... proved.

Step-by-step explanation:

It is given that there are three vectors z1 = a1 + ib1, z2 = a2 + ib2 and z3 = a3 + ib3. Now, we have to prove (a) z1 + z2 = z2 + z1 and (b) z1 + (z2 +z3) = (z1 + z2) + z3.

(a) z1 + z2 = (a1 +ib1) + (a2+ ib2) = (a1 +a2) + i(b1 +b2) {Adding the real and imaginary parts separately}

Again, z2 + z1 =(a2 +ib2) + (a1 +ib1) = (a2 +a1) + i(b2 +b1) {Adding the real and imaginary parts separately}

Hence, z1 +z2 =z2 + z1 {Since, (a1 +a2) = (a2 +a1) and (b1 +b2) = (b2 +b1)}

(b) z1 + ( z2+ z3 ) = [a1 + ib1] + [(a2 + a3 ) + i(b2 + b3 )] = ( a1 + a2 + a3) + i( b1+ b2+b3) {Adding the real and imaginary parts separately}

Again, (z1+z2)+z3 = [(a1+a2) +i(b1+b2)]+[a3+ib3] = ( a1 + a2 + a3) + i( b1+ b2+b3) {Adding the real and imaginary parts separately}

Hence, z1 + ( z2+ z3 )=(z1+z2)+z3 proved.
