Answer:

x=5, y = 9/5

Step-by-step explanation:

x+5y = 14

3x - 10y = -3

Multiply the first equation by 2

2(x+5y) = 2*14

2x+10y = 28

Add this to the second equation to eliminate y

2x+10y = 28

3x - 10y = -3

----------------------

5x + 0y = 25

Divide by 5

5x/5 = 25/5

x = 5

Now find y

x+5y =14

5+5y = 14

Subtract 5 from each side

5-5+5y = 14-5

5y = 9

Divide by 5

5y/5 = 9/5

y = 9/5

xz_007 [3.2K]

Answer:

300 divided by 6

Step-by-step explanation:

Given that;

Number of crates of apple owned by fruit seller = 3 crates

Number of apples in each crate = 100 apples

He packed 6 apples in 1 box;

Unknown:

Number of boxes needed to pack all the apples = ?

This problem is pretty straight forward;

Number boxes needed to pack all apples = $\frac{Number of crates owned by fruit seller x number of apples per crate}{Number of apples per box}$

Input the parameters and solve;

Number of boxes need to pack all apples = $\frac{100 x 3}{6}$ = $\frac{300}{6}$

So the solution is 300 divided by 6

raketka [301]

$810 ÷ 3 = 270 square feet
Area of the room is 270 square feet.

Area = 270 square feet, length = 18 feet

Area = Length x Width
270 = 18 x width
Width = 280 ÷ 18
Width = 15 feet

The room is 15 feet wide.
