Yosef's average weekly fuel cost would be $2537.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Yosef drove 12,900 miles last year. His truck's fuel efficiency averages 15 mpg.
Karla used 12900/15 = 860 gallons to drive 12900 miles.
The average cost of gas last year was $2.95 per gallon.
Therefore, Yosef's average weekly fuel cost would be
2.95 x 860 = $2537

Answer:
a = -3/2 = -1.5
Step-by-step explanation:
(1+ax) (2+3x)³
Formula
(a+b)^3=a^3+3a^2b+3ab^2+b^3
(1 + ax) [ 2^3 + 3*2^2*3x + 3*2*(3x)^2 + (3x)^3]
(1 + ax) [ 8 + 12*3x + 6*9x^2 + 27x^3]
8 + 12*3x + <u>6*9x^2</u> + 27x^3 + 8ax + <u>36ax^2</u> + 54ax^3 + 27ax^4
coefficient of x^2 is zero
54x^2 + 36ax^2
54 + 36a = 0
36a = -54
a = -3/2
Answer:
=−36p+52x+1324
Step-by-step explanation:
7x−7+35−34p+45x−2p+64
=7x+−7+35+−34p+45x+−2p+1296
Combine Like Terms:
=7x+−7+35+−34p+45x+−2p+1296
=(−34p+−2p)+(7x+45x)+(−7+35+1296)
=−36p+52x+1324
The first thing that he has to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a " 1 " in front of the parentheses, to help them keep track of the minus sign. Here's what the subtraction looks like, when working horizontally/
Answer:
x=3 is the number
Step-by-step explanation:
Suppose number be "x".
Equation will be
7x + x = 24
8x = 24
x = 24/8
x = 3
