Hh i know how to do this but i need doing so-

Step-by-step explanation

So you need the fraction to equal 2.4 and you don't know the numerator. 5 times 2.4 equals 12 so the numerator has to equal 12 so the answer is c

  x = 4

Step-by-step explanation:

Undo what is done to the variable, in reverse order. The variable is multiplied by 3/5 and 0.5 is subtracted from the result.

__

To undo those operations, first you undo the subtraction by adding 0.5 to both sides of the equation. This gives you ...

  3x/5 = 2.4

To undo the multiplication by 3/5, you can multiply by the inverse of that value, 5/3. Multiplying both sides of the equation by 5/3 gives ...

  x = (5/3)(2.4) = 12/3

  x = 4

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
