The bigger of two numbers is four more

Mathematics
1 answer:
Otrada [13]3 years ago
7 0

Answer:

X=the smaller

y=the larger

The bigger of two numbers is four more than the smaller, then:

y=x+4

one more than twice the smaller is the same as the larger, then

1+2x=y

We have the following system of equations:

y=x+4

y=2x+1

We solve this system by equal values method:

x+4=2x+1

x-2x=1-4

-x=-3

x=3

We find the value of "y"now:

y=x+4

y=3+4

y=7

the values of x and y are:

x=3

y=7

Solve for x in the equation x^2-12x+36 = 90
kicyunya [14]

Step-by-step explanation:

{x}^{2}  - 12x + 36 = 90 \\  {x}^{2}  - 12x - 54 = 0 \\

Let a=1, b=-12, c=-54

Use formula

\frac{ - b +  -  \sqrt{ {b}^{2} - 4ac } }{2a}

You will get

x = 6 + 3 \sqrt{10}  \\ x = 15.48683298 \\  or \\ x = 6 - 3 \sqrt{10}  \\ x =  - 3.48683298

Yosef drove 12,900 miles last year. His truck's fuel efficiency averages 15 mpg, and the average cost of gas last year was $2.95
bogdanovich [222]

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
