Answer:
The answer to your question is:
61.- 25
62.- 26
Step-by-step explanation:
61.-
2(5x + 5) + 2(2x) = 360
10x + 10 + 4x = 360
14x = 360 - 10
14x = 350
x = 350/14
x = 25
62.-
2(4x - 4) + 2(3x + 2) = 360
8x - 8 + 6x + 4 = 360
14x - 4 = 360
14x = 360 + 4
14x = 364
x = 364 / 14
x = 26
Answer:
numero uno, ok
Step-by-step explanation:
Experimental probability means what the probability is concluded by the experiment / trials / real results
Assuming {Section 3 I 32} , means it landed there 32 times out of 80.
We write this as a fraction:
32/80 , we simplify it:
16/40
8/20 <- notice how i'm just halving until I can't anymore
4/10
2/5 <- the simplest answer
The answer is D) 2/5
Answer:
71°
Step-by-step explanation:
31-3x+19x-5=90
16x=90-26
16x=64
x=4
m<R=19x-5 = 19(4)-5 = 76-5 = 71
Answer:
12
Step-by-step explanation:
The least common multiple of {6,8,12} is 24. This can be intuitively figured by noting that any multiple of 12 is a multiple of 6 and that 12 is 1.5x larger than 8. That means we only have so multiple 12 by 2 and 8 by 3 for them to be equal. The GCF of {20,42,72} is 2 as the prime factorization of 20 is 2x2x5 and 42 is 2x3x7. That means even without having to check 72 (which is clearly even so 2 is a factor), we know that 2 is the greatest common factor that they could share. So X/Y = 24/2 = 12
