Answer:
n = 5.5
Step-by-step explanation:
4n - 10 = 12
4n = 12 + 10
4n = 22
n = 22/4
n = 5.5
You can solve using the pythagorean theorem which is
a^2+b^2=c^2 where a and b are the legs and c is the hypotenuse in a right triangle.
12^2+x^2=24^2
144+x^2=576
x^2=432
x =20.78 (approximately)
Answer: We will write ‘3’ in the second space. Therefore, the final number must be 2. 6 ÷ 3 = 2. There is a second way that we could use inverse operations to write this multiplication as a division
Step-by-step explanation:
Answer: you would expect 6 to qualify for bonus round
Step-by-step explanation: because the 7 out of 14 qualified for the bonus round wich is 1/2 so 1/2 of 12 would be 6
The way I like to solve proportions is by cross multiplying and dividing. First yo multiply the diagonals and then you divide by the other number. So if your proportion is 7/5 = x/3, your equation would be 7*3/5. So 7*3 is 21, so your equation is now 21/5. With some long division, you'll see that 21/5 = 4.2 That's your answer, feel free to ask more questions if you need!!(:
