Y = x - 6....so sub in x - 6 for y in the other equation
3x + 2y = 8
3x + 2(x - 6) = 8
3x + 2x - 12 = 8
3x + 2x = 8 + 12
5x = 20
x = 20/5
x = 4
y = x - 6
y = 4 - 6
y = -2
solution is (4,-2) <==
The number of pretzels and hot dog sales will be 33 and 48.
<h3>What is the solution to the equation?</h3>
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Let x be the number of pretzels and y be the number of hot dogs.
Joanie runs the concession stand for the school's baseball games.
At each game, the best-selling items are pretzels and hot dogs.
Pretzels are $3 each, and hot dogs are $2 each.
Today she sold 15 more hot dogs than pretzels and made $195 in total sales. Then the equations will be
y = x + 15 ....1
3x +2y = 195 ...2
From equations 1 and 2, then we have
3x + 2(x + 15) = 195
3x + 2x + 30 = 195
5x = 165
x = 33
Then the value of y will be
y = 33 + 15
y = 48
Then the number of pretzels and hot dog sales will be 33 and 48.

Answer:
base: 4
exponent: 3
numerator: 1
denominator: 64
Step-by-step explanation:
4^4 * 4^-2: Here you subtract 2 from 4 (just basic rules)
so you get 4^2/4^5
4^2/4^5: you subtract 5 from 2 (also basic rules)
then you would get 4^-3
To put in positive exponents you do 1/4^3
which gets you 1/64
