That would be the same as : 10 × (x + 8)
Okay, so it's asking for the product of 10, and the sum of 8 and k. Sum is the answer to an addition problem, so that would make the last of it 8 + k. And we'd be multiplying this with 10, so that would make it : 10 × (x + 8)
Answer:
15
Step-by-step explanation:
5 X 10 = 50
170 / 50 = 3 sets = 15
Answer:
60
Explanation:
The multiples of 10 are 10,20,30,40,50,60,70 etc.
The multiples of 12 are 12,24,36, 48, 60
The smallest number which is a multiple of both 10 and 12 is 60
Or express both numbers in prime factor form:
10 =2x5
12=2x2x3
2 is common to both so the LCM is 2x2x3x5=60
<span>a. 7 fireflies are caught per minute.
b. 19 fireflies were already caught prior to the contest starting.
a.
Looking at the equations (3m + 13) and (4m + 6) where m is equal to the number of minutes since the contest began, it's obvious that there are 3+4 = 7 fireflies caught per minute.
b.
One again, look at the two equations. Or for that matter, calculate them both and add the results for m=0 (the moment the contest began). And upon doing so, you'll see that 13 + 6 = 19 fireflies were caught prior to the competition starting.</span>
Answer:
