konstantin123 [22]

Answer:

y = \sqrt{\frac{x-3}{3} }

Domain = [3, infinity)

Step-by-step explanation:

x = 3y^2 + 3

3y^2 = x - 3

y^2 = (x-3)/3

y = \sqrt{\frac{x-3}{3} }

100 is 1/10 of what?
lawyer [7]

\boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<h3>Further explanation  </h3>

The question can be rewritten to \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ M \ }  

This case about equations with one variable. We have to solve this calculation to obtain the value of M. Our task is to isolate the variable M alone at the end of the process on one side of the equation until the variable will be equal to a value on the opposing side.  

Let's arrange it into an equation, i.e., \boxed{ \ 100 \ = \ \frac{1}{10} \times \ M \ }  

Turn this equation over so that the position of variable M is on the left side.  

\boxed{ \ M \times \frac{1}{10} = 100 \ }  

Both sides are multiplied by 10 to isolate M on the left side. The fraction are eliminated.  

\boxed{ \ M \times \frac{1}{10} \times 10 = 100 \times 10 \ }  

M = 1,000  

Therefore, we have calculated the number that was asked.  

Hence \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<u>Note:  </u>

The significant thing to carry out is how to manipulate both sides of the equation with the algebraic properties of equality such as:  

  • Adding  
  • Subtracting  
  • Multiplying, and/or  
  • Dividing both sides of the equation with a similar number

And the commutative property of multiplication, i.e., \boxed{ \ a \times b = b \times a \ }

Austin made 5 quarts of his special from-scratch cupcake mix. He was able to make 32 identical cupcakes using 3.5 quarts of his
storchak [24]

9514 1404 393

Answer:

  no

Step-by-step explanation:

We can write a proportion to find how much mix is required to make 52 cupcakes.

  quarts/cupcakes = 3.5/32 = x/52

Multiplying by 52, we find ...

  x = 52(3.5/32) = 5.6875 . . . quarts needed for 52 cupcakes

This is more mix than Austin made. He does not have enough left for 20 more cupcakes.
