Evan has a SUV that goes 25 miles for each gallon of gas. He has 8 gallons of gas in his gas tank. How many miles can Evan drive? Susan has a small fuel-efficient car that goes 38 miles for each gallon of gas. She has 10 gallons of gas in her gas tank. How many miles can Susan drive?

Evan = 200 miles

Susan = 380 miles

Step-by-step explanation:

Evan:

Step 1:

25 miles × 8 gallons

200 miles

Susan:

Step 1:

38 miles × 10 gallons

380 miles

Hope This Helps :)

200 and 380 miles

Step-by-step explanation:

We multiply the rate by the number of gallons to find the total distance. Evan has a rate of 25 miles for each gallon, and he has 8 gallons. 25x8=200. He can drive 200 miles

The same method is used to find Susan's distance. She has a rate of 38 miles per gallon and has 10 gallons. 38x10=380

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
