Answer:
The price of the shirt is $7.50
The price of the pants is $18.50
Step-by-step explanation:
If you want to write something for your proof of work:
4x + 3x = 85.50
3 (4x + 3y ) = 3 (85.50)
12x + 9y = 256.50
12 × 7.50 = 90
9 × 18.50 = 166.50
ALSO for the last question:
12 × 7.50 = 90
20 × 18.50 = 370
370 + 90 = $460.00
Answer:
70x³ - 73x² - 155x + 168
Step-by-step explanation:
Given
(5x - 7)(2x + 3)(7x - 8) ← expand the first pair of factors using FOIL
= (10x² + x - 21)(7x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
10x² (7x - 8) + x(7x - 8) - 21(7x - 8) ← distribute the 3 parenthesis
= 70x³ - 80x² + 7x² - 8x - 147x + 168 ← collect like terms
= 70x³ - 73x² - 155x + 168
Answer:
0.35
Step-by-step explanation:
we know that
The formula to use for uniform distribution is equal to
where,
b is the upper limit of the distribution which is 5 minutes in this case.
a is the lower limit of the distribution which is 0 minutes in this case.
x is the concerned value which is 1.75 minutes in this case.
substitute the given values
That means
The probability that a randomly selected passenger has a waiting time less than 1.75 minutes is 0.35
Answer:
(x-4)(6x-6)
Step-by-step explanation:
hello :
6x²-30x+24 = 6(x²-5x+4) =6(x-4)(x-1)=(x-4)(6x-6)
