Answer:
the answer will be 121
Step-by-step explanation:
because 513 + 130= 643 then 121 + 643 = 764
121
The missing number is 121. I got this by doing 764-130-513=121. You would do this because you are trying to find the number that would allow 130 and 513 to add up to 764.
Another way to look at this problem is 513+130= 643
764-643=121
In conclusion, 513+121+130=764
wiat ill work this out for you
1 mile for every 0.6 hours
0.5 x 2 = 1
3/10 x 2 = 6/10
2 miles = 1.2 hours
285
1175 divided by 412 = 2.85194174757
that would be around 2.85
x = -70
x/10 = -7
Multiply each side by 10
x/10*10 = -7*10
