Answer:
B
Step-by-step explanation:
20x2 is 40, so 50x2 is 100
Going from 107 to 98 is (minus 9)
going from 98 to 90 is (minus 8)
going from 90 to 83 is (minus 7)
going from 83 to 77 is (minus 6)
following this pattern, the number after 77
is 77 minus 5 = 72
therefore your answer is 72
I think 88 I’m so sorry if I’m wrong
Answer:
4. -1/2
5. 1
6. 1/5
Step-by-step explanation:
Let side B = X
Then side A = 2x
Side C = 2x +1
Mow you have x + 2x + 2x+1 = 76
Simplify:
5x +1 = 76
Subtract 1 from both sides:
5x = 75
divide both sides by 5:
x = 75 /5
x = 15
Side A = 2x = 2*15 = 30 cm
Side B = x = 15 cm
Side C = 2x +1 = 2*15 +1 = 30+1 = 31 cm
