5x + 3 + x +4= 55. Solve for x. Please show your work. (This is Algebra, by the way.)

Answers

Answer 1

Answer:

x=8

Step-by-step explanation:

We first simplify both sides of the equation so it turns out like this:

(5x+x) + (3+4) =55

6x+7=55

Then we subtract 7 from both sides:

6x+7-7=55-7

6x=48

From there we divide both sides by 6:

6x/6=48/6

x=8

Answer 2

Answer:es 8

S tep-by-step explanation:

5x+ 3 + x + 4 =55

6x= 55-7

6x= 48

x= 8

HELP!!!!!HELP!!!!When solving proportion based on data from graphs, why do you often convert from fractions and percents to decimals? URGENT!! PLEASE EXPLAIN IN DETAIL!!

Answers

Answer:

It'll simplify the calculation process.

Step-by-step explanation:

It'd be much harder to solve the problem "1/4 x 14" or "25% x 14" than just calculating "0.25 x 14". It'll also help you work on converting to different forms of numbers. Depending on the problem, you'll need to convert to a specific form, such as a problem that asks you to calculate the percent increase/decrease. If you answered with your number in decimal or fraction form, you haven't completely answered the problem. I hope this helps and sorry if it wasn't in enough detail! ♥️

When converting a factions and percentages to a decimal it will often make it easier for the problem to be solved so you do not have to simplify.

-294 ÷ -14. Please show your work!!!!!

Answers

Answer:

Step-by-step explanation:

To solve the problem you can just leave the negatives behind for a while.

You then divide 294 by 14 using the normal method of division you prefere.

The answer you get is 21.

So now when the signs of the numbers are the same (negative or positive) The answer after dividing is always a positive number thus the answer remain 21.

HOPE IT HELPED

Answer:

Ignore any negative sign for now.

294÷14

Use the algorithm method.

_______

14 / 294

- 28

-------------

Now consider the signs. Two negatives make a positive

−294,−14→Positive

That Means −294÷−14=21

The answer is 21

I hope this helps and good luck. :D

Answers

For this question, we can use the same side interior angle theorem.

Angles 1 and 2 are same side interior angles, which means that they are the interior angles on the same side.

To find the angle measure of the angles, we can plug in the value we have.

[tex]A=6x+18[/tex]

[tex]A=6(10)+18[/tex]

[tex]A=60+18[/tex]

[tex]A=78[/tex]

[tex]B=9x+12[/tex]

[tex]B=9(10)+12[/tex]

[tex]B=90+12[/tex]

[tex]B=102[/tex]

To find if the oars are parallel, we can use the same side interior angle theorem, which states that if the same side interior angles are supplementary, the lines are parallel.

[tex]78+102=180[/tex]

Seeing as the angles are supplementary, the oars are parallel to each other.

Hope this helps.

At Safeway, chicken wings are $2.59 for ½ pound. How much would 3 pounds of chicken wings cost?

Answers

Answer:

3 pounds of chicken wings would cost $15.54

Step-by-step explanation:

½ pound times 2 is 1 pound.

$2.59 × 6 = $15.54

Answer:

$15.54

Step-by-step explanation:

The first step in working out the total of 3 pounds would be to convert 1/2 into a decimal. You can do this by dividing the numerator of 1 by the denominator of 2, this gives you 0.5.

Now that you have worked out 1/2 as a decimal, the next step would be to multiply 3 by 0.5, this gives you 6. This is because you are working out how many times 1/2 a pound goes into 3 pounds.

The final step would be to multiply the price of $2.59 by the quantity of 6, this gives you $15.54.

1) Divide 1 by 2.

[tex]1/2=0.5[/tex]

2) Multiply 3 by 0.5.

[tex]3*0.5=6[/tex]

3) Multiply 2.59 by 6.

[tex]2.59*6=15.54[/tex]
