I'm pretty sure I did that right, it's been a while since I've done this. But I'm pretty sure
Answer:
b=3.1cm
Step-by-step explanation:
2a+b=15.7

b=3.1cm
Answer: 55.56
Step-by-step explanation:
Let the unknown number be k
(45 x k) / 100 = 25
45k/100 = 25
multiply both sides by 100
45k = 25 x 100
45k = 2500
divide both sides by 45
k = 2500/45
k = 55.56
