Answer:
2(2-10)/3=x
Step-by-step explanation:
2(2-10)=3x
let the required number be x then
So 60 is 40% of 150.
4x-2y=-12
Answer: 0.8(.50)^t/5
P(t)= p^0(1+-r)^t
0.8= initial mass
.50= 100/2-> halving
t/5= how many times for every 5 days
circumference = pi*d
70cm*pi = 219.8cm
219.8cm × 240 rev = 52752 cm
52752cm/100 = 528m
