-4c+25+c=3c+79

Answers

Answer:

c = -9

Step-by-step explanation:

- 4c + 25 + c = 3c + 79   Combine like terms.

- 4c + c + 25 = 3c + 79

- 3c + 25 = 3c + 79

- 3c + 3c + 25 = 3c + 3c + 79

25 = 6c + 79

25 - 79 = 6c + 79 - 79

- 54 = 6c

-54/6 = 6c/6

-54/6 = c

-9 = c

There aren't 2 answers, you could have 2 answers if one of the c's was squared. Here is another way to do the math.

- 4c + 25 + c = 3c + 79

- 4c + c + 25 = 3c + 79

- 3c + 25 = 3c + 79

- 3c - 3c + 25 = 3c - 3c + 79

- 6c + 25 = 79

- 6c + 25 - 25 = 79 - 25

- 6c = 54

- 6c/- 6 = 54/- 6

c = 54/- 6

c = - 9

Answer:

-9 = c

Step-by-step explanation:

-4c+25+c=3c+79

-3c +25 =3c+79

25 = 6c +79

-54=6c

-54/6 = c

-9 = c

Answer:

Step-by-step explanation:

The covers ( there are 2) are

2* .9 mm = 1.8 mm

Depending on how they are defining pages

If they are defining pages as the number of papers

400 pages at .13 =

400 *.13 = 52 mm

total = 2 covers + 400 pages

       = 1.8 + 52

       53.8 mm

If they are defining pages as the page numbers

Each page number is on the front and back so 400/2 = 200 pieces of paper

200 pages at .13 =

200 *.13 = 26 mm

total = 2 covers + 400 pages

       = 1.8 + 26

       27.8 mm

Answer:

52.8 mm thick

Step-by-step explanation:

0.9mm X 2mm90 = 1.8 mm

0.13mm X 400mm = 52 mm

1.8mm + 52mm = 53.8 mm

Sophie went to the lake with her family. First, they spent 1 1 4 hours fishing. Then, they spent twice as much time swimming. How much time did they spend fishing and swimming in all?

Answers

Answer:

The total time spent on both fishing and swimming is 3 3/4 hours

Step-by-step explanation:

Here, we are interested in knowing the total time spent on fishing and swimming.

From the question, we are made to know that the time spent fishing is 1 1/4 hours or simply 5/4 hours.

Then they spent two times of this time swimming.

The time spent swimming is thus 5/4 * 2 = 5/2 hours

So the total time spent on both swimming and fishing will be;

5/4 hours + 5/2 hours = (5 + 10)/4 = 15/4 = 3 3/4 hours

The width of a rectangle measures (2.5u+9.8)(2.5u+9.8) centimeters, and its length measures (1.5u+3.9)(1.5u+3.9) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answers

Solution,

We have,

Width of rectangle, b = (2.5u+9.8) cm

Length of rectangle, l = (1.5u+3.9) cm

We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by:

Perimeter = 2(l+b)

P = 2[(2.5u+9.8)+(1.5u+3.9)]

Collecting like terms

P = 2[(2.5u+1.5u)+(9.8+3.9)]

P=2(4u+13.7)

⇒ P = 8u+27.4

So, the expression for the perimeter of the rectangle is (8u+27.4) cm.

Last year, Andrea ran about 120 kilometers during the months of March, April, and May. Estimate how many more kilometers she ran during those three months than she ran this year. Round to the nearest 1 kilometer. A 2-column table with 3 rows titled Total Distance Andrea Ran (kilometers). Column 1 has entries March, April, May. Column 2 has entries 48.7, 31.2, 35.66.

Answers

Answer:

March=49

April=31

May=36

Andrea ran about 116 km

this is about 4 km less than last year

Step-by-step explanation:

I got it right :))

Andrea ran 4 km extra last year if, and the total distance run this year is 120 km, The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.

What is subtraction?

The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given:

Total distance run this year = 120 km,

The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.

Calculate the total distance = 48.7 + 31.2 + 35.66

The total distance this year = 115.56 or 116 km

Calculate the difference as shown below,

Distance = 120 - 116 = 4 km,

Thus, she ran 4 km extra last year.

Simplify 1,999,999 with an exponent of 0

Answers

The value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰

Before we can simplify with an exponent of zero, first we must understand that any number raised to the power of zero gives 1. Hence:

1,999,999 = 1,999,999 × 1

Since 1 can be expressed as 10⁰, the value becomes:

1,999,999 = 1,999,999 × 10⁰

Hence the value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰

Answer:

y=-2x-1

Step-by-step explanation:

first take 2 points from the graph to find m ( linear equation y=mx+b)

(-1,1) and (-2,3)

m=y2-y1/x2-x1

m=3-(1)/-2+1

m=2/-1

m=-2

now find b at point -1,1

y=-2 x+b

1=-2(-1)+b

Anusha is walking on a hiking trail at a rate of Three-fourths miles in One-fourth hour. At this rate, how far will Anusha walk in an hour?

Answers

Answer:

Step-by-step explanation:

3/4 + 3/4 + 3/4 + 3/4 = 12/4 = 3. She will walk 3 miles in an hour.

The distance that Anusha covered in one hour is 3 miles

If Anusha is walking on a hiking trail at a rate of three-fourths miles in One-fourth hour, this is expressed as:

3/4 miles = 1/4 hours

We need to get the rate of Aisha that is the distance traveled in an hour

x = 1 hour

Divide both expressions

3/4x = 1/4

Cross multiply

4x = 3 * 4

4x = 12

x = 12/4

x = 3

Hence the distance that Anusha covered in one hour is 3 miles

I have 5digits My name is worth 90,000 my two is worth 2 thousand one of my sevens is worth 70 the other is worth 10 times as much my other digit is a six what number am I

Answers

Answer:

92776

Step-by-step explanation:

From the given question,

The analysis of the given question can be computed as follows:

I have 5 digits

My name is worth                      90000

my two is worth                            2000

one of my seven is worth                 70

and the other is worth 10 times

as much i.e 10× 70 = 700                700

my other digit is six                               6

What number am I?

So, we are expected to look for the summation of all the numbers

i.e   90000 + 2000 + 70 + 700 + 6

= 92776

Thus, the number is 92776
