I do not get how to do Simpliflyng Radicals.

Answers

First step: Find out the prime numbers that make up the radical, for example, 120 would be 2x2x2x5x3
Second step: If there is 2 of the same number that repeats just put that number in the front of the resulting radical
Third: Just multiply the remaining radicals together and put the number in front of it.
Now you have
2 √(30)
Example Simplify 252
Step 1: Find the prime factorization of the number inside a radical.252 = 2 x 2 x 3 x 3 x 7 
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
√252 = √2 x 2 x 3 x 3 x 7
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.2 x 3√7 
Step 4: Simplify the expressions both inside and outside the radical by multiplying.6√7

The ratio of adults to children at a picnic is 4 to 5. The total number of people at the picnic is 27. How many adults and children are at the picnic? Include steps.

Answers

There are 12 children and 15 adults at the picnic.

Add together the ratios 4 and 5 and divide the amount of people by that number (so 27 divided by 9)

You then get 3. So then multiply both sides of your ratio by 3. (4:5 ----> 12:15)

Hope this helps a little.

Is y=4x-5 proportional

Answers

Answer: A proportional relation between two numbers, x and y is when:

y= k*x, where k is a real number.

this is read as "the number y is k times the number x" so y is proportional to x, and the constant of proportionality is k.

The equation in the problem is: y = 4x - 5, here you have an x-intercept equal to -5, this quantity breaks the proportionality relation. So in this case y is not proportional to x.

No it's not proportional because it would be like y=4x. And proportional relationship doesn't have any operation between the “k” and “x” where K is the unit rate or the constant of proportionality!

Help me solve this question what do I do

Answers

the question said estimate so
4 and 1/2 is in the middle so leave it

3 and 5/6 is like 4

so 4 and 1/2-4=1/2 but the answer is actually more less since we made 3 and 5/6 go up
so the answer is more than 1/2

(1/2-1/6 =3/6-1/6=4/6=2/3)
so u need to convert the fractions which are 9/2 and 23/6 then u make them have the same denominator so 9/2=27/6 and 27/6-23/6 = 4/6
