Which property was used to simplify the expression?

3c+9+4c= 3c+4c+9
distributive property
commutative property
associative property
inverse property

Answers

Answer 1
It would be the commutative property because the commutative property means that we can swap the places of two numbers. The numbers 4c and 9 were swapped to make the problem easier.

To help Its sales, the company should focus on producing size
T-shirts. Approximately % of T-shirts the company
makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000,

Answers

Answer:

To help Its sales, the company should focus on producing Large

T-shirts. Approximately 80% of T-shirts the company

makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000, 3,300

of these will likely be size small.

Step-by-step explanation:

In the survey, Large t-shirts are most frequently bought so they should be the primary focus if the company is trying to make more money.

To find the percentage of shirts that the medium and large shirts make up, first you find the total amount of shirts (11+37+83+19=150), then you will find how many mediuma and large shirts (37+83=120). Percentage is (120/150)*100=80%

To find the number of small shirts you can set up a proportion.

[tex]\frac{11}{150} =\frac{x}{45,000}[/tex], then cross multiply

150x=11*45,000

150x=495,000

x=3,300

Answers

Answer:

4 hours

Step-by-step explanation:

Circumference formula:

C = πd

Use the given value and find the diameter:

138 = 3.14dr = 138/3.14r = 43.94 ≈ 44 yards

When given a system of equations in​ slope-intercept form, is graphing or substitution the most efficient method to​ solve? Explain.
Choose the best answer below.
A.
Substitution is the only method that should be used if the answer involves integer values. If the answer involves values that are not​ integers, graphing would be more efficient because an exact answer can be obtained. It is easier to read graphs when the point of intersection does not occur at integer values.
B.
Graphing is the only method that would be appropriate to use here because it is not possible to use the substitution method if both equations are in​ slope-intercept form.

In my honest opinion, I would say D. B and C don’t make much sense to me, and I don’t believe A is correct either. So yeah, I’d say D.

D. Graphing and substitution are appropriate to use if the answer involves integer values.

It can be difficult to read graphs if the intersection point does not have integer values so this would be an inefficient method to solve with.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, a system of equations in​ slope-intercept form y₁ = m₁x₁ + b₁ and

y₂ = m₂x₂ + b₂.

We can use both substitution and graphing depending on the numerical values of the variables.

If the solution involves integer numbers, graphing and substitution are the proper methods to utilize. Substitution would be more effective since an accurate solution may be reached if the solution involves values that are not integers. If the intersection point doesn't have integer values, it can be challenging to understand graphs, so using this approach to solve would be ineffective.
