it cost 270 for 3 people to go on a fishing trip how much does it cost for 10 people to go on the fishing trip

sdas [7]

270 divided by 3 = 90.

90 is the cost per person.

Now you do 90 times 10 to get the total for all 10 people.

90 times 10= 900.

Homework: Geometry, part I (Perimeter)

Sindrei [870]

Answer:

(I don't know if this is correct)

To find the length of the rectangle, you need to first do 20 x 2 = 40 because when you finding the perimeter you have to do W + L + W + L = P (or Wx2 + Lx2 = P). You then subtract 40 from 68 (68 - 40) where you get 28 left. you then just divide 28/2 and you get 14. I may be way off but that's how I learned it.

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. Match the linear equations with their x-

jolli1 [7]

Answer:

Part 1) $x-2y=2$ ----> (2,0) and (0,-1)

Part 2) $-3x+3y=7$ ----> (-7/3,0) and (0,7/3)

Part 3) $7x-y=21$ ----> (3,0) and (0,-21)

Part 4) $3x-5y=-20$ ----> (-20/3,0) and (0,4)

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

The x-intercept is the value of x when the value of y is equal to zero

Part 1) we have

$x-2y=2$

1) <u><em>Find the x-intercept</em></u>

For y=0

$x-2(0)=2\\x=2$

the x-intercept is (2,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

$0-2y=2\\y=-1$

the y-intercept is (0,-1)

Part 2) we have

$-3x+3y=7$

1) <u><em>Find the x-intercept</em></u>

For y=0

$-3x+3(0)=7\\x=-\frac{7}{3}$

the x-intercept is (-7/3,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

$-3(0)+3y=7\\y=\frac{7}{3}$

the y-intercept is (0,7/3)

Part 3) we have

$7x-y=21$

1) <u><em>Find the x-intercept</em></u>

For y=0

$7x-(0)=21\\x=3$

the x-intercept is (3,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

$7(0)-y=21\\y=-21$

the y-intercept is (0,-21)

Part 4) we have

$3x-5y=-20$

1) <u><em>Find the x-intercept</em></u>

For y=0

$3x-5(0)=-20\\x=-\frac{20}{3}$

the x-intercept is (-20/3,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

$3(0)-5y=-20\\y=4$

the y-intercept is (0,4)
