Answer:

Answer is √202 or 14.21267

Step-by-step explanation:

d^2=(4−(−7))2+(5−(−4))2

d^2=(11)2+(9)2√

d^2=121+81

d^2=2–√202

d= 12.21267

Suppose you walk 2 miles in 35 minutes. 4. write a proportion to find how far you would walk in an hour if you were to continue
Mrac [35]
Distance traveled in 35 minute = 2 miles.

So distance traveled in one minute = 2/35 (miles/minute)
                                                             = 0.0572 miles / minute.

So distance traveled in one hour  , we can find by multiplying it from 60.Because in one hour there is 60 minute.

SO distance traveled in one hour = 0.0572 * 60 
                                                          = 3.432 miles / hour.

Four more than -3 times a number is equal to 8 more than -4 times the same number
postnew [5]

Answer:

The equation is 4 + ( − 3 x ) = 8 + ( − 4 x ) and the answer is x=4

Explanation:

Let us call the number  

x

and write our condition as:

4 + ( − 3 x ) = 8 + ( − 4 x )

rearranging: 4 x − 3 x = 8 − 4

x = 4
