A truck can travel 140 miles on 7 1/2 gallons of gas. How far can the truck travel with 16 gallons of gas ?

Lunna [17]

298.6 miles

you can solve this by setting up a proportion

ie. 140 miles over 7.5 gallons set it equal to X miles over 16 gallons.
Cross multiply to find 7.5x=2240 and divide by 7.5 to get 298.6 miles on 16 gallons of gas

hope this helped!

3/4x + 11 - 5 1/2 + 1/4x

scoray [572]

$\frac{3}{4} x + 11 - 5 \frac{1}{2} + \frac{1}{4} x$

$( \frac{3}{4} x + \frac{1}{4} x) + (11 - 5 \frac{1}{2} )$

$(\frac{3x}{4} + \frac{x}{4} ) + (11 + - \frac{11}{2} )$

$( \frac{(3x + x)}{4} ) + ( \frac{22}{2} - \frac{11}{2} )$

$\ \frac{4x}{4} + \frac{11}{2}$

$x + \frac{11}{2}$

Madison has set up a lemonade stand outside her house and sells small cups and large cups of lemonade. Each small cup holds 12 o

Troyanec [42]

Answer:

$12x+22(y+10)=1240, y=x$

small cups=30

large cups=40

Step-by-step explanation:

let x be the number of small cups and y the number of large cups.

-Given that 10 more cups than small cups of lemonade were sold:

$12x+22(y+10)=1240$

#Before the 10 more were sold, the number of x and y sold were equal>

$x=y\\\\\therefore 12x+22(x+10)=1240\\\\12x+22x+220=1240\\\\34x=1240-220\\\\34x=1020\\\\x=30$

The number of small cups sold was 30

#Since, the number of large cups was 10 more, y=x+10=30+10=40
