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:

2400

5400

8400

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

Answer:

A. You have to complete your own estimation however, by looking at it, mine is about 11 miles.

B. 11.75 or 11 3/4 miles

We can estimate that Evelyn ran about 11.5 miles in practice last week and Evelyn ran exactly [tex]11\frac{3}{4}[/tex] miles in practice last week.

A fraction represents a part of a whole.

To estimate how many total miles Evelyn ran in practice last week, we can round each of the distances to the nearest half-mile and add them up:

[tex]3\frac{1}{4}[/tex] = 3.5, [tex]2\frac{1}{8}[/tex] = 2, [tex]2\frac{7}{8}[/tex] =3, [tex]1\frac{3}{4}[/tex] =1.5 and [tex]1\frac{3}{4}[/tex]=1.5

Adding these rounded distances, we get:

3.5 + 2 + 3 + 1.5 + 1.5 = 11.5

Therefore, we can estimate that Evelyn ran about 11.5 miles in practice last week.

The exact total number of miles Evelyn ran last week in practice, we need to add up the distances exactly.

[tex]3\frac{1}{4}[/tex] =13/4,

[tex]2\frac{1}{8}[/tex] = 17/8,

[tex]2\frac{7}{8}[/tex] =23/8,

[tex]1\frac{3}{4}[/tex] =7/4 and

[tex]1\frac{3}{4}[/tex]=7/4

Adding the fractions, we get:

[tex]\frac{13}{4} +\frac{17}{8}+\frac{23}{8}+\frac{14}{8}+\frac{14}{8}[/tex]

LCM of denominators is 8

[tex]\frac{26}{8} +\frac{17}{8}+\frac{23}{8}+\frac{14}{8}+\frac{14}{8}[/tex]

= [tex]\frac{94}{8}[/tex]

Evelyn ran exactly [tex]11\frac{3}{4}[/tex] miles in practice last week.

Hence, we can estimate that Evelyn ran about 11.5 miles in practice last week and Evelyn ran exactly [tex]11\frac{3}{4}[/tex] miles in practice last week.

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.

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
