A sporting goods store sells shirts for $20 each. If the store offers a 40% discount, what will be the selling price of each shirt? $12, $8, $28, or $16​

Answers

Answer 1

Answer:

The selling price for each shirt would be 8 dollars.

Step-by-step explanation:

10% of $20 is 2 and to make a whole would be 10% x 10 = 100%

so 2 x 10 = 20

we could break this down to 2+2+2+2+2+2+2+2+2+2=20

we know that one 2 is 10% so to make 40% we need 4.

4 x 2 = 8

The system of equations below has exactly one (x, y) pair for its solution.

4x+6y=244x+6y=24
2x+y=82x+y=8
If we double each side of the second equation, 2x+y=82x+y=8, we have 4x+2y=164x+2y=16. Explain why the same pair that is the solution to the system is also a solution to this new equation.
If needed, you can support your explanation with hanger diagrams (upload a picture), or by inventing a situation that the equations represent.
If we add the two equations in the original system, we have 6x+7y=326x+7y=32. Explain why the same (x, y) pair is also a solution to this equation.
Again, you can support your explanation with diagrams or a situation, if needed.

a(q-8)=23

solve for q

help appreciated! ​

Answers

Answer:

q= (23+8a)/a

Step-by-step explanation:

a(q-8)=23

or, aq-8a = 23

or, aq = 23+8a

or, q = (23+8a)/a

(I’m not sure if the A is part of the question or if A is what question you’re answering but I’ll work o for both)

A(q - 8) = 23

Multiply everything inside the brackets by A:

aq- 8a = 23

Divide both sides by a to isolate q - 8a:

q - 8a = 23 / a

Add 8a to both sides to isolate q:

q = 23 + 8a² / a

Without the A:

q - 8 = 23

Add 8 to both sides to isolate q:

q = 31

the number y of calories burned after x hours of rock climbing is represented by the linear function y=650x find the domain , is the domain descents or continuous? explain

Answers

Answer:

The domain is discrete

Step-by-step explanation:

Given

[tex]y = 650x[/tex]

Required

What type of domain is it?

Based on the given options, the domain is continuous.

From the question, we understand that x represents the hours spent in climbing the rock.

The climber can decide to climb for 1 hour, 2 hours, ½ hour, ⅓ hour, ¼ hour, etc..

A domain is said to be discrete if it can only take integers (i.e. whole numbers), if otherwise, it is continuous;

So, since x is not limited to only whole numbers, then we can conclude that the domain of x is continuous

Solve for z:

Step-by-step explanation: Step 1. Simplify the both sides of the equation: [tex]14=z+12[/tex].

Step 2. I flipped the equation that looks like this: [tex]z+12=14[/tex].

Last but not least is step 3. Subtract 12 from the both sides: [tex]z+12-12=14-12[/tex]; ∴, your answer should be z=2, I hoped this helps, Happy New Year, and mark me as brainliest. :D
