Answer:
The answer is 12.8.
Step-by-step explanation:
0.16 times 80 = 12.8
Wrong subject, but that is true. You should have information to back that up also.
The angles will add up to 180 degrees.
the numbers are 6 and 13
let x be one of the numbers then the other is 2x + 1
their sum increased by 7 = 26
x + 2x + 1 + 7 = 26
3x + 8 = 26
subtract 8 from both sides
3x = 26 - 8 = 18
divide both sides by 3
x =
= 6
the numbers are 6 and (2 × 6) + 1 = 12 + 1 = 13
13 because you do 18-8 and you get 10 and divide that by 2 and you get 5 then add 5 to 8 and you get 13 and subtract 5 from 18 and you get 13 as well. Hope that helps
