Answer
8kg
Explanation
3/4--------15
2/5-------x
cross multiplying
3/4×X = 2/5×15
3X/4 = 30/5
3X/4 = 6
cross multiplying
3X = 4×6
3X = 24
dividing bothsides by 3
3X /3 = 24/3
X = 8
therefore, the answer is 8 kg
Answer: 5 minutes
Step-by-step explanation:
We know that 1760 yards are in a mile. We can convert the given info into a proportion. 440/75 = 1760/x, where x is the number of seconds it takes to run a mile. Cross-multiply to get 440x = 75*1760. Divide both sides by 440 to get x = 75*4 = 300 seconds. The problem asks for how many minutes so you have to convert 300 seconds to minutes. To do this, we have to divide 300 by 60 to get 5 minutes.
Its going more horizontal because the slope has you go up 1 and right 4, meaning you are going right more than you are going up
Regroup terms
p - 3/4 = 1/2
Add 3/4 to both sides
p = 1/2 + 3/4
Simplify 1/2 + 3/4 to 5/4
<u>p = 5/4</u>
