grin007 [14]3 years ago

5 0

Answer:

Step-by-step explanation:

80,120,160.....

This is an arithmetic sequence

common difference (d) = 2nd term - 1st term

= 120 - 80 = 40

first term (a) = 80

nth term = a + (n-1)d

= 80 + (n-1)*40

= 80 + 40n -40

= 40 + 40n

What is the weight of one half of two thirds of a sack of rice? The sack of rice weighs 99 kilograms.

Eddi Din [679]

First you need to find what 2/3 equals
to do this, take 99 divided by 3
99/3=33

if 1/3 equals 33, two thirds would be 33x2
33x2=66

now, you need to find 1/2 of 66. this can be done 2 different ways

1. 66 divided by 2 - 66/2=33
OR
2. 66 x 1/2 = 33 OR 66 x .5 = 33

The answer is 33 kilograms
