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:

see below

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

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 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

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.

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.

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.

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

b+2=1

b=1-2 ⇒ b=-1

y=-2 x -1

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

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
