Answer:

Missing number = 68

Step-by-step explanation:

You can simply set up an equation like so: $x+(-56)=12$ .

Then, proceed to solve by isolating the x by itself.

x+(-56)=12

+56 +56 <--- Do the opposite operation on both sides to cancel the 56.

x=68

A quick pointer: A number plus a negative number is just subtracting so you can just work backwards.

Answer: 68.

After 3.5 hours, Patrick had traveled 217 miles. If he travels at a constant speed, how far will he have traveled after 4 hours

Ede4ka [16]

Answer: He would have traveled 248 miles

Explanation: This is a ratio

To find how many miles he would have traveled after 4 hours, we need to apply the information givin into a ration table

(We can put miles on the top and hours on the bottom)

217 ?
------- ------
3.5 4

Now, we can do two things:
1. cross multiply
we would take 217 times 4 (868) and divide that by 3.5 (248)

2. Divide the top and bottom by 3.5 (numerator= 62 denominator= 1)
multiply 62 by 4 to get 248

Hope this helps!
