Which of the following equations is equivalent to ab − 8 = 3b, when solving for b .
a = 11
b = 8/2a
b = -8/3 - a
b = -8/a - 3

Answers

It would be B=-8/a-3

The equivalent equation for the given equation is b=8/(a-3).

What is an equivalent equation?

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.

The given equation is ab-8=3b.

Now, transpose 3b to other sides of an equation, we get

ab-3b=8

b(a-3)=8

b=8/(a-3)

Therefore, the equivalent equation for the given equation is b=8/(a-3).

Answer: 0.000021 in scientific notation is

2.1 × 10-5

Step-by-step explanation:

All numbers in scientific notation or standard form are written in the form

m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.

To convert 0.000021 into scientific notation, follow these steps:

Move the decimal 5 times to right in the number so that the resulting number, m = 2.1, is greater than or equal to 1 but less than 10

Since we moved the decimal to the right the exponent n is negative

n = -5

Write in the scientific notation form m × 10n

= 2.1 × 10-5

Therefore,

2.1 × 10-5 is the scientific notation form of 0.000021 number and 2.1e-5 is the scientific e-notation form for 0.000021

Educator: Like many other difficult pursuits, music requires intense study and practice from an early age in order for one to become proficient. But many school music programs encourage only children who demonstrate early aptitude to continue studying music, while children who do not appear especially musical are directed towards other activities. Having learned to think of themselves as musically inept, these children do not devote any time to music, and thus some of them deprive themselves of the opportunity to develop latent but potentially significant musical talent.The educator's statements, if true, would best support which of the following conclusions?(A) Music education should not devote special attention to talented students.(B) Everyone has the potential to learn music.(C) Talent is not always apparent at an early age.(D) Children are particularly sensitive to criticism from adults.(E) All children should study music.
