If it takes 4 gallons of gas to drive 92 miles, how many miles can be driven using 6 gallons of gas?

138 miles

Step-by-step explanation:

4 gallons=92 miles

6 gallons=x miles

Cross multiply the two equations

4 *x = 92*6

4x=552

Divide both sides by 4

4x/4=552/4

x=138miles

Alternatively,

4 gallons=92miles

6 gallons=x miles

Divide 92 miles by 4 gallons

92miles/4gallons=23miles/gallons

If 1 gallon=23miles

Then, 6miles multiplied by 23gallons=138miles

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
