A. 8/$12=21/$x then cross multiply. B. 1/$1.5
The answer is nine because eighteen subtract nine is nine
Answer:
Step-by-step explanation:
So we have:
Remove all the fractions to make things simpler. To do so, we can multiply by the LCM of the denominators.
The denominators are 3 and 7.
The LCM of 3 and 7 is 21. Thus, multiply everything by 21:
Distribute:
Simplify the fractions:
Add 12x to both sides:
Subtract 9 from both sides:
Divide both sides by 26:
Reduce:
And that's our answer :)
Step-by-step explanation:
so you do 90km X 1000 to get meters per hour
divide 90,000 by 60 to get seconds
get whatever the answer above was and times it by 5 to get how far it travels in 5 seconds
Answer:
Any radical in the form can be written using a fractional exponent in the form . The relationship between and works for rational exponents that have a numerator of 1 as well. For example, the radical can also be written as , since any number remains the same value if it is raised to the first power.
