Convert 7.7km into miles if 1.6 km = 1 mile
Lemur [1.5K]
This is a simple equation.  

The equation is y = 1.6x  with y being the miles and x being the kilometers.

Lets plug the kilometers in.

Y=1.6(7.7)

1.6 *  7.7 = 12.32

12.32 miles is  equal to 7.7 kilometers

HOWEVER

There are about .6 miles in a kilometer, so if you typed this wrong I don't know.  

It is still the same concept.

Y = .6x

Y = .6(7.7)

.6 * 7.7 =  4.8

In this case there are 4.8 miles in 7.7 kilometers

PLZ HELP ASAP! IM FAILING SO PLEASEEEE
UkoKoshka [18]

Answer: B

You can find slope by using the slope formula. Because we are already given two coordinate points, we can use that to find our slope. The slope formula is \frac{y^{2}-y^{1}  }{x^{2}-x^{1} }. This also refers to \frac{5-(-5)}{0-4} or 10/-4 or -5/2. Any coordinate with the x-value as 0 means that that coordinate is the y-intercept. Because (0,5) has 0 as its x-value, the y-intercept is 5.

ser-zykov [4K]
Because to find the perimeter of a shape you have to add all the sides together so you would take 26.46 and divide it by 4 (since squares have 4 sides) to get 6.165
