I got -5 & 2/5 because
2/3x and 3/5 can be made into
20/30x and 18/30

And then by adding 2 to -2
And adding 2 to 4

The equation becomes
20/30x + 6 = 18/30

Then I subtracted 6 from 18/30 and got
20/30x = -5 & 2/5

Then simplified that to

2/3x = -5 & 2/5

That's just what I think you should do.

The math teacher gives each student a map of the amusement park that use a coordinate plane the meeting locates is at(0,0) on th
GrogVix [38]

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

To find:

The actual distance between first and second ride.

Solution:

Distance formula: Distance between two points is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using the distance formula, we get the distance between first ride and second ride in the map is

d=\sqrt{(3-0)^2+(0-4)^2}

d=\sqrt{9+16}

d=\sqrt{25}

d=5

So, the distance between first ride and second ride in the map is 5 units.

We have,

1 units  = 100 ft

5 units = 500 ft

The actual distance between first and second ride is 500 ft.

Therefore, the correct option is C.

The exchange rate at the post office is £1=€1.17 how many euros will you get for £280
4vir4ik [10]

Question

The exchange rate at the post office is £1=€1.17 how many euros will you get for £280


Answer:

<h2>327.6 €</h2>

Step-by-step explanation:

you can solve with an equation

1£ : 1.17€ = 280£ : x

1 : 1.17 = 280 : x

x = 1.17 * 280 : 1

x = 327.6

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

check

1 : 1.17 = 280 : 327.6

0.85 = 0.85

the answer is good

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

or you can simpy solve with a multiplication

280 * 1.17 = 327.6
