Use ratios to solve
15 m/8 km = x m/50 km Cross multiply
15(50) = 8x
750 = 8x divide by 8 on both sides
93.75 = x
93.75 miles = 50km
Answer:
-multiply both sides by 2, so you will have 2A= h(b+c)
- divide both sides by (b+c), so you will have 2A/(b+c)=h and this is your final answer
The converse of a mathematical statement involves simply switching the hypothesis and the conclusion, thus:
"If a triangle is isosceles, then it is equilateral."
Using proportions, it is found that the original sample weighed 
grams.
- This question is solved by <em>proportions</em>, using a rule of three.
- The weight of 1 batch, in grams, is of
. How much do the sample of 12 batches weigh?
The rule of three is:
1 batch - grams.
12 batches - x grams
Applying cross multiplication:
Applying scientific notation:
The original sample weighed grams.
