You plug in the numbers. For example, for the first one you plug in 7 to 4.9=0.7m.
You replace the m with 7 then solve. 4.9=0.7(7)
4.9=4.9
which will make the answer infinite solutions since it is a true statement.

What is 4x-5/3+2x=7+2/9x+2
ch4aika [34]

Simplifying the expression gives 36x^2 - 82x - 10 = 0

<h3>How to simplify the expression</h3>

Given the expression;

4x-5/3+2x=7+2/9x+2

\frac{4x - 5}{3 + 2x} = \frac{9}{9x + 2}

Cross multiply

4x - 5( 9x + 2) = 9 (3 + 2x)

Expand the bracket

36x^2 + 8x - 45x - 10 = 27x + 18x

Collect like terms

36x^2 + 8x - 45x - 27x - 18x = 0

Add the like terms

36x^2- 82x - 10 = 0

Thus, simplifying the expression gives 36x^2- 82x - 10 = 0

the rectangular post shown at the right measures 2w-30 by w. the poster has an area of 5400 cm^2. what is The value of w ?
borishaifa [10]

Step-by-step explanation:

w(2w - 30) = 5400

2w²- 30w = 5400

2w² - 30w - 5400 = 0

(w - 60 ) ( w + 45 ) = 0

w= 60 w= - 45

only take the positive value

therefore w = 60

When randomly selecting an​ adult, A denotes the event of selecting someone with blue eyes. What do Upper P (Upper A )P(A) and U
bezimeni [28]

Answer:

P(A): It is the probability of selecting someone with blue eyes.  

P(\bar{A}): It is the probability of selecting someone who does not have blue eyes

Step-by-step explanation:

We are given the following in the question:

A: event of selecting someone with blue eyes.

Probability:

  • The probability of an event tells the chances of happening of that event.
  • It is mathematically defined as:

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

Complement of an event:

  • It is the event that consist of all outcomes not happening in A.
  • It is represented by \bar{A}
  • P(A) + P(\bar{A}) = 1

We have to explain the representation:

a) P(A): It is the probability of selecting someone with blue eyes.

It gives us the chances of someone having blue eyes.

b) P(\bar{A}): It is the probability of selecting someone who does not have blue eyes

It is the chances of selecting someone who does not have blue eyes.
