Lucy used 3 gal of paint to cover 900 ft. She needs to cover a total of 1,100 ft?.
insens350 [35]

Step-by-step explanation:

3 gal = 900 ft

... gal = 1100 ft

So, each gal is used for cover 300 ft,

Then,

\sf \frac{1100}{900}  \times 3 =  \frac{11}{3}  =  \boxed{ \bold{ \red{3 \frac{2}{3}  \: gal}}}

We need <u>3 2/3 gal</u> to cover 1100 ft.

Hope it helps!

Brenda and Cody are selling fruit for a school fundraiser. Customers can buy small boxes of tangerines and large boxes of tanger
jenyasd209 [6]

Answer:the cost of a small box of tangerine= $11 and the cost of a large box of tangerine= $19

Step-by-step explanation:

Step 1

Let price of  small box of tangerines be represented as x

and price of large box of tangerines be represented as y

Such that the equqtion for  Brenda who sold  12 small boxes of tangerines and 1 large box of tangerines for a total of $151 be represented as

12x + y = 151--------equation 1

and

the equation for Cody who  1 small box of tangerines and 3 large boxes of tangerines for a total of $68

x + 3y= 68-------equation 2

Step 2

12x + y = 151--------equation 1

x + 3y= 68-------equation 2

By eliminaton  methd multiply equation 2 by 12

x + 3y= 68-------equation 2 x (12)

12x + 36y=816 --------equation 3

Subtract equation 1 from equation 3

12x + 36y=816 --------equation 3

-12x + y = 151--------equation 1

35y=665

y=665/35 =19

 to get x  , we substitute the value of y=19 into equation2

 x + 3y= 68

x+ 3 x 19=68

x=68-57

x=11

Therefore the cost of a small box of tangerine= $11 and the cost of a large box of tangerine= $19
