Question

Greg combined different weights of fertilizer, soil, and compost to make 29 kilograms (kg) of potting soil for some plants. The weight of fertilizer was x kg. The weight of soil was 2 kg more than three times the weight of fertilizer, and the weight of compost was half the weight of fertilizer. This is represented in the equation below:

x + (3x + 2) + one half x = 29

What was the difference in the weights of soil and compost Greg combined?

3 kg

6 kg

14 kg

17 kg

Answer 2

@johnweldon1993 can you please help me with this question when u get the chance

Answer 3

i think it's 17kg but im not real sure if it correct

Answer 4

Well lets check it

We just solve this for 'x'

x + (3x + 2) + one half x = 29

4x + 2 + 1/2x = 29

(9/2)x = 27

x = 6

Alright...so we know the soil part was

(3x + 2) when we plug in 6 for 'x' we get 20

The compost part is half the fertilizer...well since the fertilizer was just 'x'....we know that is 6

and so half of 6 is 3

So yes...17 is indeed correct^ :)

Answer 8

Ricky walked away from a mall at a constant velocity for the first 30 seconds. He stopped at an ice cream parlor for 40 seconds. He then turned around and walked toward the mall again at a constant velocity for 10 seconds. He met a friend, and they both walked away from the mall at a constant velocity for the next 20 seconds. Which of the following graphs best represents Ricky's motion?

First straight line joins ordered pairs 0, 0 and 30, 20, second straight line joins 30, 20 and 70, 20, third straight line joins 70, 20 and 80, 30, and fourth straight line joins 80, 30 and 100, 0

First straight line joins ordered pairs 0, 0 and 30, 20, second straight line joins 30, 20 and 40, 5, third straight line joins 40, 5 and 60, 50

First straight line joins ordered pairs 0, 0 and 30, 20, second straight line joins 30, 20 and 70, 20, third straight line joins 70, 20 and 80, 5, and fourth straight line joins 80, 5 and 100, 50

First straight line joins ordered pairs 0, 0 and 30, 20, second straight line joins 30, 20 and 70, 20, third straight line joins 70, 20 and 80, 5, and fourth straight line joins 80, 5 and 90, 50
