Kala drove 250 miles using 9 gallons of gas. at this rate how many gallons of gas would she need to drive 275 miles
Rus_ich [418]

Answer:

9.9 gallons

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:

\frac{9}{250}  = \frac{x}{275}

Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.

250(x) = 250x\\

275(9) = 2,475

Now, lets put the values above back into the equation:

250x = 2,475

Lets solve this equation. First we divide 2,475 by 250, making x by itself.

\frac{2,475}{250} =x

9.9 = x

This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.

Length of a rectangle is 4 inches less than twice it’s width of the perimeter is 70 inches what’s the dimensions?
Vedmedyk [2.9K]
W= width
L= length= 2W-4
Perimeter= 70

FIND WIDTH:
P= 2(L + W)
P= 2L + 2W
substitute 2W-4 for L
70= 2(2W-4) + 2W
multiply 2 by all in parentheses
70= (2*2W) + (2*-4) + 2W
70= 4W - 8 + 2W
combine like terms
70= 6W - 8
add 8 to both sides
78= 6W
divide both sides by 6
13= W

FIND LENGTH:
substitute w=13 to find width
L= 2W-4
L= 2(13)-4
L= 26-4
L= 22

CHECK:
P= 2(L + W)
70= 2(22 + 13)
70= (2*22) + 2(13)
70= 44 + 26
70= 70

ANSWER:
length= 22 inches
width= 13 inches

Hope this helps! :)
