Answer 2
Answer:

-3.8x + 7 and c = -75/14 and/or c = -5.35714

Step-by-step explanation:

First equation:

1.2x + 7 - 5x =

Step 1 - Group like terms:

1.2 - 5x + 7

Step 2 - Add simliar elements:

1.2 x - 5x = -3.8x =

3.8x + 7

Answer: -3.8x + 7

Second equation:

2.2c - 3 = 2(6 - c) + 7c =

Step 1 - Multiply both sides by 10:

2.2c ⋅ 10-3 ⋅ 10 = 2(6 - c) ⋅ 10 + 7c ⋅ 10

Step 2 - Refine:

22c - 30 = 20(6-c) + 70c =

- Expand 20(6-c): 120 - 20c

22c - 30 = 120 - 20c + 70c

Step 3 - Add similar elements:

-20c + 70c = 50c =

22c - 30 = 120 + 50c

Step 4 - Add 30 to both sides:

22c - 30 + 30 = 120 + 50c + 30

Step 5 - Simplify:

22c = 50c + 150

Step 6 - Subtract 50c from both sides:

22c - 50c = 50c + 150 - 50c

Step 7 - Simplify:

-28c = 150

Step 8 - Divide both sides by -28:

-28c/-28 = 150/-28

Step 9 - Simplify:

c = -75/14

Answer:

Fraction form: c = -75/14

Decimal form: c = -5.35714

Hey! Your question wasn't quite clear, so the most I could do was simplify both equations in a way you can hopefully understand. If these aren't the answers you were looking for, please elaborate on what I was supposed to answer!

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.

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

Evelyn is a member of her school’s track team. She competes in the mile run. Last week in practice Evelyn ran 3 1/4, 2 1/8, 2 7/8, 1 3/4, and 1 3/4miles.


A. Estimate how many total miles she ran in practice last week.


B. Exactly how many miles did Evelyn run last week in practice?

Answers

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.

What is Fraction?

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.

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:

Do you know how mirage happen?The beginning of the mirage was due to the difference in temperature density between cold air and hot air temperatures in the atmosphere above the earth's crust. Cool air temperatures have a denser and heavier density than hot air temperatures which have a lower density and are lighter. Because of this, the hot air layer will be close to the soil layer and trapped by the cooler air layer above it, so that the light will refract towards the horizontal line on the view and travel upwards due to the internal influence. Total internal reflection is a process of light reflection that occurs on the boundary surface between one medium and another, which has a smaller refractive index, if the angel of incidence to the second medium exceeds a certain critical angel. And the light that is in a medium with a high refractive index will travel to a medium with a lower refractive index.
