Answer:
x=7.4
Step-by-step explanation:
2.4+x=9.8
(x=9.8-2.4)
x=7.4
Answer:
24.08
Step-by-step explanation:
We use the Pythagorean theorem and we get (16)^2 + (18)^2 = (x)^2
256 + 324 = x^2
x^2 = 580
x is about 24.08.
Answer:
60
Step-by-step explanation:
12=2⋅2⋅3
15=3⋅5
We see that they both share 3 is their LCM.
We divide each number by their LCM.
123⇒4
153⇒5
We multiply these two quotients and the LCM to get our final answer:
3⋅4⋅5=60
That is our answer!
