11.5 gallons = 11.5 x 28miles = 322 miles
b) IF 1 gallon costs 2.89
11.5 gallons will cost= 11.5 x 2.89= 34.391

solve for x -1/2x + 1/3 > 3/5
Answers
Answer:
x > 8/15
Step-by-step explanation:
x -1/2x + 1/3 > 3/5
Combine like terms
2/2x - 1/2x +1/3 > 3/5
1/2x + 1/3 > 3/5
Subtract 1/3 from each side
1/2x + 1/3 -1/3 > 3/5 -1/3
1/2x > 3/5 -1/3
Get a common denominator
1/2x > 9/15 - 5/15
1/2x > 4/15
Multiply each side by 2
2 * 1/2x > 4/15 * 2
x > 8/15
It is X > 8/15
U is the midpoint of TV. If TU = 6x and TV = 11x + 8, what is TV?
T
6x
V
11x + 8
Simplify your answer and write it as a proper fraction, mixed number, or integer.
Answers
Answer:
96
Step-by-step explanation:
U is the midpoint of TV, so mTU is half of mTV or mTV = 2 * mTU, so
mTV = 2 * mTU
11x + 8 = 2 (6x)
11x + 8 = 12x
8 = x
mTV = 11x + 8 = 11(8) + 8 = 88 + 8 = 96

Answer:
2. 4x³ - 2x² + 4y
3. (2x+3)(2x−5)² (To expand, it would be 8x³ - 28x² - 10x + 75)
Step-by-step explanation:
2.
(4x³ + 2y) - (2x² - 2y)
Find the opposite of 2x² - 2y by finding the opposite of each term.
4x³ + 2y - 2x² + 2y
Add 2y and 2y to get 4y.
4x³ - 2x² + 4y
3.
To simplify this expression, simply multiply 2x - 5 by itself to get (2x + 3)(2x - 5)².
I know this is extra, but I'll expand it out.
(2x + 3)(2x - 5)²
Use binomial theorem (a−b)² =a²−2ab+b² to expand (2x−5) ²
(2x + 3)(4x² - 20x + 25)
Use the distributive property to multiply 2x + 3 by 4x² - 20x + 25.
8x³ - 40x² + 50x + 12x² - 60x + 75
Combine -40x² and 12x² to get -28x².
8x³ - 28x² + 50x - 60x + 75
Combine 50x and -60x to get -10x.
8x³ - 28x² - 10x + 75
