When solving for a quantity in a formula, what are the most important things to consider? What process do you follow in order to be sure that you've correctly solved for some quantity? Explain your reasoning, and give examples to help illustrate your ideas. Don't forget to respond to your peers' posts by reviewing what they've read and attempting to apply their ideas to other examples. Remember, your goal is to demonstrate whether you've made sense of their ideas or not, and to contribute to help everyone improve their explanations.

Pre-algebra

If the student is taking this branch of mathematics, they are expected to show their work because they're expected to solve specific problems in a certain way. Ex, when they're solving for a variable they're supposed to manually find the value of x by isolating it rather than entering the left and right hand of the equal sign in the calculator (in slope-intersect form) and finding the intersection point. If they only get the correct answer without showing work, we give them 2 points. 8 more points if work is shown.

Algebra

Students in algebra are expected to know how to get the correct answer. We don't care how they do it, as long as it's the correct answer.

As you can see, the numbers are the same, but the order of the decimal is different.

Since the order of the decimal is different, so will the answer.

1,860 and 0.0186 do have the same numbers in them, but since the decimal is located in different spots, then the answer will be different with different values.

You might not see the decimal in 1,860, but it is after the 0.....

1,860.0 ( same thing just added a decimal, but it is the same value)

Soos is spending money at an average rate of $5 per day. After 9 days, he has $25 left.


How much money did Soos have at the beginning (on day 0)?

y - 5= 9(x - 25)

Answers

Answer:

$70

Step-by-step explanation:

According to the problem, calculation of given data are as follows:

Spending money at rate = $5 per day

After 9 days money left = $25

We can calculate the money on day 0 by using following formula,

y = mx + b

Here, y = money left after 9 days

m = rate of spending money

x = number of days

b = money on day 0

So, by putting value, we get

$25 = (-5 × 9 ) + b

b = $25 + $45

= $70

Answers

Answer:

The solution to the system of equations is:

[tex]x=10,\:y=4[/tex]

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}[/tex]

Multiply -x+8y=22 by 5:  -5x+40y=110

[tex]\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}[/tex]

so adding the equations

[tex]-5x+40y=110[/tex]

[tex]+[/tex]

[tex]\underline{5x-4y=34}[/tex]

[tex]36y=144[/tex]

solve 36y = 144 for y:

[tex]36y=144[/tex]

divide both sides by 36

[tex]\frac{36y}{36}=\frac{144}{36}[/tex]

Simplify

[tex]y=4[/tex]

For 5x-4y=34 plug in y=4

[tex]5x-4\cdot \:4=34[/tex]

[tex]5x-16=34[/tex]

Add 16 to both sides

[tex]5x-16+16=34+16[/tex]

Simplify

[tex]5x=50[/tex]

Divide both sides by 5

[tex]\frac{5x}{5}=\frac{50}{5}[/tex]

Simplify

[tex]x=10[/tex]

Therefore, the solution to the system of equations is:

[tex]x=10,\:y=4[/tex]
