Tems11 [23]

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.

Find the student’s error in solving the following inequality.
Mars2501 [29]

Answer:

The correct option is:

The student should have switched the direction of the inequality sign to get –5> x for a final answer

Step-by-step explanation:

The students has made a mistake in the 3rd step.

We know that when we multiply or divide any negative number on both sides of the inequality, the sign of inequality  reverse its direction.

In step 3 the student divided 25 by -5 but did not  switch direction of the inequality sign.

Therefore the correct option is: The student should have switched the direction of the inequality sign to get –5> x for a final answer

I need help with this math problem. I have a picture of the question.
Svetlanka [38]

Formula for distance between two points is

d∧2=(x2-x1)∧2+(y2-y1)∧2 in our case (x1,y1)=(k,q) and (x2,y2)=(0,0)

d∧2=(0-k)∧2+(0-q)∧2= k∧2+q∧2 => d=√(k∧2+q∧2)

Good luck!!!
