Step-by-step explanation:

Okay! To do this you need to have x on one side (isolate the variable) and also combine like terms. Like terms are terms with the same exponent and variable, like 8x and 6x.

8x+1=-6x-2 To combine like terms here we have to move -6x to the other side of the equation by adding it (using inverse operations). 8x+6x=14x

14x+1=-2 now subtract 1 from both sides.

14x=-3

Divide both sides by 14 and x=-3/14

What is the solution to the equation below? Round your answer to two

Answer:

D. x=5

The answer is x=4.50 then it is rounded off to 5. So, the answer is 5.

Step-by-step explanation:

Find the domain of the inequality: $2x-1\geq 0$

Rearrange terms to the left side of the equation: $2x\geq 1$

Divide both sides of the inequality by the coefficient of the variable:

=> $x\geq \frac{1}{2}$

The domain of the inequality is: $x\geq \frac{1}{2}$

Convert logarithm to exponential form: $2^{3}=2x-1$

Calculate the power: $8=2x-1$

Rearrange terms to the left side of the equation: $-2x= -8-1$

Calculate: $-2x=-9$

Divide both sides of the equation by the coefficient of the variable: $x=\frac{-9}{-2}$

=> $x=\frac{9}{2}$

=> $x=4.5\\$

Round the number: $x=4.50$

Answer: $x=4.50$

=> $x=5$

Please help I don’t understand

Olegator [25]

Answer:

They are not similar.

Step-by-step explanation:

To find whether or not they are similar, set them up as a proportion.

(2.4/5.2) = (8/13)

Now cross multiply.

2.4*13 = 5.2*8

31.2 = 41.6

Since they are not exact, they are not similar.

Marion bought 14 packages of plastic frog and lizard fishing lures. She bought frog lures in packages of 4 and lizard lures in p

tatuchka [14]

Answer:

Marion bought 6 frog lures and 8 lizard fishing lures.

Step-by-step explanation:

Let $f$ represent frog lures and $l$ represent lizard lures.

The total packages Marion bought is

$f+l=14...eqn1$

If she bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures, then

$4f+6l=72...eqn2$

We make $f$ the subject in equation 1 and put it into equation 2 to get;

$f=14-l...eqn3$

We put equation 3 into equation 2 to get;

$4(14-l)+6l=72$

$\Righttarrow 2(14-l)+3l=36$

We expand the bracket to get;

$28-2l+3l=36$

$-2l+3l=36-28$

$l=8$

We put $l=8$ into equation 3 to get;

$f=14-8$

$f=6$

Therefore Marion bought 6 frog lures and 8 lizard fishing lures.
