(MARKING BRAINLIEST) Kareem cannot decide which of two washing machines to buy. The selling price of each is ​$390. The first is marked down by ​40%. The second is marked down by 10​% with an additional ​30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.

Answers

Answer:

See explanation

Step-by-step explanation:

The selling price is ​$495.

The first washing machine:

- is marked down by 30​%

$495 - 100%

$x - 100% - 30% = 70%

Find the value of x:

The second washing machine:

- is marked down by 20​% with an additional 10​% off

$495 - 100%

$y - 100% - 20% = 80%

Find y:

Now,

$396 - 100%

$z - 100% - 10% = 90%

Find z:

Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.

The selling price is $495

four times a number x is at least -12
an inequality is ?
the solution is ?

Answers

Answer:

-16

Step-by-step explanation:

im just taking a guess.

x+4>-12

  -4   -4

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

4's cancel out and -12+-4=-16

Again this is just a guess.

The inequality is 4x ≥ -12 and the solution of this inequality is x ≥ -3.

What are Inequalities?

Inequalities are the expressions having two sides connected with inequality symbols. Inequality symbols are <, >, ≤, ≥ and ≠. They may contain one or more variables and constants.

Inequalities which consist of one or more variables with the highest degree of the variables being 1 is called Linear inequalities.

Given that four times a number is at least -12.

Thus the inequality says that 4 multiplied with a number x, which is 4x has values -12 or greater than -12.

So the inequality is 4x ≥ -12.

Solving this,

4x ≥ -12

Dividing both sides by 4, we get,

4x/4 ≥ -12/4

x ≥ -3

Hence the inequality is 4x ≥ -12 and the solution is x ≥ -3.

Consider the two functions below. Which one of these functions is linear? What is its equation? Enter any answers to two decimal places.

Answers

Answer:

Function A and the equation would be y = 1.6666666666~x + 0

Step-by-step explanation:

A linear function is a function that is a straight line with no change so function B does not fit that description. So than it has to be A

To find the equation you first what to find the slope of the line

ΔY/ΔX = 5/3 = 1.666666666666

Take the slope and multiply it by x to get y

Following are the solution to the given function:

Given:

Function A:

[tex]\bold{x} \ 3 \ 6 \ 9 \ 12 \ 15 \\\\\bold{y} \ 5 \ 10 \ 15 \ 20 \ 25[/tex]

To find:

Find the function=?

Solution:

Function A or equation would've been [tex]\bold{y = 1.6666666666 \sim x + 0}[/tex].The linear equation is a straight line with really no modification, hence function B doesn't suit its description. As a result, it has to be A.You must first calculate the slope of the line to solve this equation.[tex]\bold{\to \frac{\Delta Y}{ \Delta X} = 5/3 = 1.666666666666}[/tex]To get y, take the slope then multiply this by x.

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!

Answers

Answer:

Step-by-step explanation:

To calculate the speed of each one we proceed as follows:

speed=distance/time

a] Noah's speed:

distance=2.5 miles

time=3/5 hours

speed=(2 1/2)/(3/5)

=(5/2)/(3/5)

=5/2×5/3

=25/6

=4 1/6 mi/hr

Emily's speed

distance=3 3/4 miles

time=5/6 hour

thus

speed=(3 3/4)/(5/6)

=15/4)/(5/6)

=15/4×6/5

=4 1/2 mi/hr

Anna's speed:

distance=3 1/3 miles

time=3/5

speed=(3 1/3)/(3/5

=(10/3)/(3/5)

=10/3×5/3

=5 5/9 mi/hr

Anna was the fastest

Which would be used to solve this equation? Check all that apply.

subtracting 3 from both sides of the equation
multiplying both sides of the equation by 3
dividing both sides of the equation by 3
substituting 4 for p to check the solution
substituting 36 for p to check the solution

Answers

Answer:

1 3 4

Step-by-step explanation:

umm i suck at explaining sorry

Answer: Multiplying both sides of the equation by 3

substituting 36 for p to check the solution

Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.

Then you have 3(p/3) = 3(12)

p = 36 simplify

To check this work, you can substitute 36 for p:

36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work
