can i pls get help on wat 2x - 3 = 15?

Answers

Answer: x = 9

Step-by-step explanation:

Step 1: Add 3 to both sides.

2x − 3 + 3 = 15 + 3

2x = 18

Step 2: Divide both sides by 2.

2x/2 = 18/2

x = 9

The answer is 9.

You’d move all terms that don’t contain x to the right side and solve it.

Answers

Answer:

20 square meters

Step-by-step explanation:

To do this continue the line of the top of the rectangle so you split the figure into a triangle and a rectangle. The dimensions of the rectangle would be 8 by 2, so 8 * 2 = 16. Next, the dimensions of the triangle would be (4 - 2) by (8 - 4) = 2 by 4. The area would then be 2 * 4 = 8/2 = 4.

All you have to do now is add those two areas together, 16 + 4 = 20 square meters.

During the holiday sale, the store discounted all items 1/3. What is the discount on a $19.95 item? plz help me

Answers

Answer:

Discount Final Price Each

1/3 off $ 19.95. $ 13.30

Step-by-step explanation:

I think its 13.30

Answer: $13.30

Step-by-step explanation: If you multiply 19.95 by 1/3 you will get the answer 6.65, that is the amount that is taken off. So next, you can just subtract 6.65 from 19.95.

19.95-6.65=13.30

So that is the answer, with the discount the item is now $13.30

How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 inches, and height 2 inches?

Answers

Answer:

432

Step-by-step explanation:

3x1/3 inch cubes make 1 inch

2x3+2 = 8

3x3 = 9

3x2 = 6

length x width x height

8x9x6 = 432

432 because 3x1/3 inch cubes is 1 inch
2x3+2=8
3x3=9
3x2=6
using length x width x height
8x9x6=432

I'm having some trouble with this question (picture included)

Answers

Answer:

2400

5400

8400

Step-by-step explanation:

You need to know the Divisibility Rules for 3, 5, and 8.

For 3: If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.

For 5: If the last number is either 0 or 5, the entire number is divisible by 5.

For 8: If the last three digits of a whole number are divisible by 8, then the entire number is divisible by 8.

You can put 0 to the end to meet the requirements of the divisibility rule of 5,

so it should be like _ _ _ 0

for 8, you can use 400 so it should look like _ 400

For 3, the sum of the digits needs to be divisible by 3

if we say X to the first digit the sum of the digits is x+4

we can use 6 and 9, so x can be 2, 5, and 8.

Therefore we have:
