charle [14.2K]

Answer:

The price of adult's ticket is $ 17.73 And

The price of children's ticket is $ 13.85

Step-by-step explanation:

Given as :

The Prices for adult ticket and child ticket in the city zoo is different

Let the price for adult's ticket = $ A

And The price for child's ticket = $ C

Now, according to question :

3 A + 2 C = $ 80.89 And

2 A + 3 C = $ 77.01

Now solve the both equation

So, 2 × (3 A + 2 C) = 2 × $ 80.89 And

3 × (2 A + 3 C) = 3 × $ 77.01

I.e

6 A + 4 C = $ 161.78 And

6 A + 9 C = $ 231.03

Now, ( 6 A + 9 C ) - ( 6 A + 4 C ) = $ 231.03 - $ 161.78

Or, 5 C = $ 69.25

Or, C = $ 13.85

And Put the value of C in above any eq

6 A + 4 × ($ 13.85) = $ 161.78

Or, 6 A = $ 161.78 - $ 55.4

Or, 6 A = $ 106.38

∴ A = $\frac{106.38}{6}$

Or, A = $ 17.73

Hence The price of adult's ticket is $ 17.73 And

The price of children's ticket is $ 13.85 Answer

I NEED HELP PLEASE. LOOK AT PICTURE

Bond [772]

Answer:

Part 1) $\frac{a^4}{4b^2}$

Part 2) $-\frac{v^9}{w^6}$

Step-by-step explanation:

we know that

When divide exponents (or powers) with the same base, subtract the exponents

Part 1) we have

$\frac{3a^{2}b^{-4}}{12a^{-2}b^{-2}}=(\frac{3}{12})(a^{2+2})(b^{-4+2} )=\frac{1}{4}a^{4}b^{-2}=\frac{a^4}{4b^2}$

Part 2) we have

$\frac{v^3w^{-3}}{-v^{-6} w^3} =-v^{3+6}w^{-3-3}=-v^9w^{-6}=-\frac{v^9}{w^6}$
