Answer:
No, we can't make 20 by adding 5 odd numbers.
Step-by-step explanation:
An odd number is represented by 2n+1, the sum which we got is represented in this form, so it's obviously an odd number. But 20 is an even number, so sum can't be 20.
150/75 = 2 hours
150/60 = 2.5 hours
150/50 = 3 hours
150/20 = 7.5 hours
0.49 as a fraction is 49/100
Your answer is B: 49/100
Make the big number x and the small y
5y=x; x-1=(y+3)3; now substitute. 5y-1 = 3y+9. 2y=10 y is 5x is 25
Answer:
60x
Step-by-step explanation: this would be applying the distributive property
40x+30x-10x
70x-10x
