Answer:

A 28 and 45

Step-by-step explanation:

So keep in mind that columns must add up to the total numbers, and rows must add up to their total numbers.

We know that what goes in the box canoeing + swimming is

x + 43 = 71.

It needs to add up to 71!

x = 71 - 43 = 28

We know that what goes in the box no swimming + no canoeing is

34 + y = 79

It needs to add up to 79.

y = 19 - 34 = 45

So the answer is A. 28 and 45.

Now, I did this with the columns, but you could easily do this with the rows and get the same result!

A tree casts you say shadow that is 9 feet long at the same time a person standing nearby casts a shadow that is 3 feet long if

inna [77]

we have that

Applying proportion

x/9=5.5/3

solve for x

x=9*(5.5/3)

x=16.5 ft

therefore

<h2>the answer is 16.5 ft</h2>

Solve each system using elimination. − 5 = −10 − + = 6

Maksim231197 [3]

The values of (x, y) are (-5, 1), if the equations $x-5y=-10$ and $-x+y=6$ are solved by elimination method.

Step-by-step explanation:

The given is,

$x-5y=-10$ ................................(1)

$-x+y=6$ .....................................(2)

Step:1

Equation (2) is multiplied by -1 ( Eqn (2) × -1 )

$x-y=-6$ ..................................(3)

Step:2

Substrate the equation (1) and equation (3),

$x-5y=-10$

$x-y=-6$

( - )

After the Subtraction equation becomes,

$(x-x)+(-5y+y)=(-10+6)$

$(0)+(-4y)=(-4)$

$-4y=-4$

$y=1$

Step:3

By using y value find value of x,

$x-5y=-10$

$x-(5)(1)=-10$

$x=-10+5$

$x=-5$

Step:4

Check for solution,

$-x+y=6$

$-(-5)+1=6$

$6=6$

Both sides are equal so answer is corrected

Result:

The values of (x, y) are (-5, 1), if the equations $x-5y=-10$ and $-x+y=6$ are solved by elimination method.

joey can paint a room in 2 hours and chelsea can paint the same room in 3 hours. if they work together how long would it take to

JulijaS [17]

Answer:

$1.2\ hours$

Step-by-step explanation:

we know that

Joey can paint a room in 2 hours

That means

Joey can paint the 100% of the room-------> 2 hours

In 1 hour ------> can paint 100%/2=50%

Chelsea can paint a room in 3 hours

That means

Chelsea can paint the 100% of the room-------> 3 hours

In 1 hour ------> can paint (100%/3)=33.33%

therefore

Joey and Chelsea in 1 hour can paint -----> 50%+33.33%=83.33%

by proportion

$\frac{1}{83.33}\frac{hour}{\%} =\frac{x}{100}\frac{hour}{\%}\\ \\x=100/83.33\\ \\ x=1.2\ hours$
