Answer:
11,200
Step-by-step explanation:
Given that the lcm of a and b is 40 then a and b are factors of 40. All the multiples of 40 as sets are 1 and 40, 2 and 20, 4 and 10, 5 and 8. Of all these, only 5 and 8 would give a lcm of 40.
Let a = 5 and b = 8 as such,
7 a^2 = 7 * 5^2 = 175
7b^2 = 7 * 8^2 = 448
Then the lcm of 7 a^2 and 7b^2
= 11,200
To determine the factor pairs for the number 30, simply find out the smallest set of numbers that will multiply to give 30, you would need to break down composite numbers to do this.
30 = 6 • 5 = 2 • 3 • 5.
These all are prime numbers that when multiplied together equals 30.
This one is worded oddly, but I think it's going to be:
(2x)/19
Ooooppppppp— homie not gettin nun at home I see
Answer:
x = 43
Step-by-step explanation:
x + 28 + 195 = 180
x + 223 = 180
x = 180 - 223
x = 43 (ANS)
I hope my answer is correct. If not I apologize.
