Answer:
Each team ran (scored) 90 runs.
Step-by-step explanation:
Don't really know how to explain it but I'll show what I did.
First I understood that for every 9 runs team A runs, team B runs 7.
This means that if we multiply 9 by a number, we have to multiply 7 by the same number.
Now that we understand this, we need to figure out a number that when multiplied with 7 and 9 then added together equals 1440.
I'm pretty sure there was an easier way to do this but I did it the way I know will for sure give me the right answer and that's estimating that mystery number until you get it. Sorry my explanation wasn't the best.
Work:
9 x 90 = 810
7 x 90 = 630
810 + 630 = 1440
810, based on the given conditions, formulate 1440 x 9 ÷ (9 + 7)
Calculate 1440 x 9=12960 then Calculate 9+7 =16 12960 over 16 = 810
Calculate 1440 x 9=12960 then Calculate 9+7 =16 12960 over 16 = 810
