213 is 30% of what amount

Mathematics

WITCHER [35]3 years ago

Start by calling the unknown amount 'x'. We can then set up a relationship to represent the question:

213 = (30\%) \times x
or
213=0.3x

and then solve for x, by dividing both sides of our equation by 0.3

\frac{213}{0.3}=\frac{0.3x}{0.3}
710=x

213 is 30% of 710

To check: 710 \times 0.3 = 213

How do you solve quadratic equations?
masha68 [24]
In any equation there is a variable (usually x). In a quadratic equation there is a lot involved.

-B (+or-) sqrt of b^2 - 4 x A x C
________________________  divide it by
               2 x A
                                                   There is usually an original equation that looks like:  Ax^2 + Bx + C = 0    Use the variables from the equation to the left to fill the upper equation.  (You can also look up a better formula if confused).

To Find :  the greatest number of rows possible  each row has the same

number of marigold plants and the same number of rose plants.​

Solution:

marigold plants  = 28

rose plants = 36

To find  the greatest number of rows possible  if each row has the same

number of marigold plants and the same number of rose plants.​

we need to find HCF of 28 and 36

28 = 2 x 2 x 7

36 = 2 x 2 x 3 x 3

HCF = 2 x 2  = 4

greatest number of rows possible  is 4
