Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner that costs $59?

Answers

Answer:

No

Step-by-step explanation:

90% -> 423

470-423 = 47 (what he left after buying laptop )

Answer:

Nope! He does not have enough.

A music store is having a clearance sale. All items are discounted by 20%. What is the sale price of a radio that regularly costs $30?

Answers

Answer:

24

Step-by-step explanation:

You would first multiply 20% by $30. Then you would get 6 and subtract 6 from $30.

Answer:

$24

Step-by-step explanation:

Method 1: find 10% of 30 = 3 (just divide 30 by 10)

then double it to make 20% = 6

subtract 6 from 30 to give 24.

Method 2: 20% = 1/5

To find 1/5 of a number, divide it by 5.

30 divided by 5 = 6.

Then subtract 6 from 30 = 24.

Method 3: to decrease a number by 20% multiply it by 0.8.

30 x 0.8 = 24

How can x minus two-thirds = StartFraction 5 over 6 EndFraction be solved for x in one step?
Add Two-thirds to both sides.
Add StartFraction 5 over 6 EndFraction to both sides.
Subtract Two-thirds from both sides.
Subtract StartFraction 5 over 6 EndFraction from both sides.

Answers

Add Two-thirds to both sides

solution:

x-2/3= 5/6

We have to find how this can be solved for "x" in one step

Remember that,

We we add or subtract same number from both sides of a equation, the equation still remains true

Therefore, from given,

x-2/3=5/6

Add Two-thirds to both sides

x-2/3+2/3=5/6+2/3

x=5/6+2/3

x=9/6

Add Two-thirds to both sides to solve the sum

Answer:

A.

Add Two-thirds to both sides.
