If two thirds of a number decreased by 20 is 40, what is the number
oee [108]

Answer:

The unknown number is 90

Step-by-step explanation:

This question requires a good understanding so as to interprets it well

And always ensure that all symbols used in representation are well stated so as to help the examiner or anyone who will mark it to understand better

So back to the question,let the unknown number be x

And two thirds of the unknown number is 2/3x

2/3x was decreased by 20 which can be written as 2/3x-20

And this decrease gives 40

That's,2/3x-20=40

Then go ahead to solve the question

Start by finding the LCM and the LCM is 3

2x-60/3=40

Cross multiply

2x-60=40×3

2x-60=120

Collect like terms by adding 60 to both sides

2x=180

Divide both sides by 2

x=90

Therefore the final answer is 90

What is liner equation with two variable?

  • An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
  • For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.

-10x² -10y² = -300 ----a

5x² + 5y² = 150 ---- b

While trying to solve this,

We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.

10x² + 10y² = 300 ----c

-10x² -10y² = -300 ---a

<u>Everything cutoff, we will </u><u>get 0</u><u>, and there is no solution to these equations.</u>

Triangle ABC is similar to triangle LMN by the AA Similarity Postulate.
abruzzese [7]
<span>Triangle ABC being similar to triangle LMN by the AA similarlity postulate means that m<A = m<L; m<B = m<M; m<C = m<N. Let m<M = x, then 81 + x + 2x = 180; 3x = 180 - 81 = 99. x = 99 / 3 = 33. Therefore, m<M = 33 degrees.Hope this helps. Let me know if you need additional help!</span>
