If you would like to know how many gallons of paint did Beth use, you can calculate this using the following steps:
1 jar ... 1 pint of paint
32 jars ... x pints of paint = ?
1 * x = 1 * 32
x = 32 pints of paint
1 gallon ... 8 pints
y gallons = ? ... 32 pints of paint
1 * 32 = 8 * y
32 = 8 * y /8
y = 32 / 8 = 4 gallons of paint
Result: Beth used 4 gallons of paint.
Answer:
Dude the hard hope someone help
Step-by-step explanation:
A) 25x+15y=650
25x+15(40)=650
Or it could be 25x=650 and 15y=650
B) No because she makes $15 for every necklace which she only has 40 necklaces 15x40=600
Answer:
The inverse is (x^2-5)/2
Step-by-step explanation:
y =sqrt(2x+5)
Exchange x and y
x = sqrt(2y+5)
Solve for y
Square each side
x^2 = (sqrt(2y+5))^2
x^2 = 2y+5
Subtract 5 from each side
x^2 -5 = 2y-5+5
x^2 -5 = 2y
Divide each side by 2
(x^2-5)/2 = 2y/2
(x^2-5)/2 = y
The inverse is (x^2-5)/2
