Alicia drove at a constant speed and traveled 182.4 miles in 3 hours. what is her rate in miles per hour

Answer:

see below

Step-by-step explanation:

x+ 7.05 = 45.3

Subtract 7.05 from each side

x+ 7.05-7.05 = 45.3-7.05

x =38.25

Let x be the number

x+3.5 = -4.3

Subtract 3.5 from each side

x+3.5 - 3.5 = -4.3-3.5

x = -7.8

x is the cost of the drawing tablet

x+ 3.95 = 6.94  correct

The second equation add the total cost plus the cost of the drawing tablet  and sets it equal to the cost of the pencils.  This is not correct

6.94+x = 3.95   incorrect

Answer:

1. x=38.25

2. -7.8

3. the second option

Step-by-step explanation:

1. x+7.05=45.3

(move the constant to the right)

x=45.3-7.05

(calculate)

x= 38.25

(answer)

2.

(you subtract -4.3 by 3.5)

3.

(you can't use $6.94 + x = $3.95 because $6.94 is your total overall so you can only use that as your end result)

Answer:

Kendal will be 60 meters away from the library after 80 seconds and again after 100 seconds.

Step-by-step explanation:

6s -540 = 60 or 6s - 540 = -60

First equation

addition property of equality: 6s -540 + 540 = 60 + 540

simplify: 6s = 600

division property of equality: 6s/6 = 600/6

simplify: s = 100

Second equation

addition property of equality: 6s -540 + 540  = -60 + 540

simplify: 6s = 480

division property of equality: 6s/6 = 480/6

simplify: s = 80

Answer:

x = 57

Step-by-step explanation:

180 degrees in a triangle

67 + 56 = 57

==================================================

Explanation:

The three angles of any triangle always add to 180

x+67+56 = 180

x+123 = 180

x+123-123 = 180-123 .... subtract 123 from both sides

x = 57

The missing angle is 57 degrees

-------------

Check:

x+67+56 = 57+67+56 = 180

Answer is confirmed.

Answer:

60n-30

Step-by-step explanation:

you would do 15 * 4n

that would give you 60. since 15 *4 is 60 and then you would just put the n

15*2 equals 30. You would make it a negative 30 since it is a negative 2.

then you would combine them and get the answer

60n-30

Answer:

AC=22

Step-by-step explanation:

The measure of the Length of AC is; 35

We are given;

ac = 5x

ab = 12

bc = 3x + 2

ab + bc = ac

Thus;

12 + 3x + 2 = 5x

14 + 3x = 5x

Subtract 3x from both sides to get;

5x - 3x = 14

2x = 14

x = 14/2

x = 7

ac = 35

Answer:

1 Pair.

Step-by-step explanation:

If I am not mistaken the question you are asking is how many pairs of numbers have a sum of 10.

5 + 5 = 10

No other number can ADD up to 10.

1 Pair is your answer.

Divine the total number of the entire chart by the number of a single line or bar to give you the ratio in a bar or line chart. For example, if a bar or line represented 5 in a chart with a total of 30, you would divide 30 by 5. This would give you a result of 6. Therefore, the ratio would be 6:1.

To solve this youd have to do 72-15 which equals out to be 68 feet.

Your answer is The submarine descended 68 feet.

Answer:b

Step-by-step explanation:

The equation for the perpendicular bisector of line segment XY is 2x + y = 7, the correct option is A.

The standard equation of a line is given by

y = mx+c

Here m is the slope and c is the y intercept

The slope can be determined by

m = (y₂ -y₁)/(x₂ -x₁)

The line segment XY  has the points  X(5, 7) and Y(–3, 3).

The slope of the line is,

m = ( 3 - 7) /( -3 - 5)

m = -4 / -8

m = 1 /2

The product of the slope of a line and a line perpendicular to it is -1.

( 1/2) * m' = -1

m' = -2

As it is a bisector , the midpoint of X and Y will be the point on the line.

Midpoint of XY is ( ( 5 -3)/2 , (7+3)/2 )

Midpoint of XY is ( 1 , 5)

The equation of the perpendicular bisector of line segment XY is,

y = -2x +c

5 = -2 + c

c = 7

So, the equation is,

y = -2x +7

2x +y = 7

I think it is C tell me if im wrong :\

Answer:

y = 5/2x - 5

Step-by-step explanation:

Step 1: Write equation

5x - 2y = 10

Step 2: Solve for x

Answer:

y = (5/2)x - 5

Step-by-step explanation:

5x-2y = 10

Subtract 5x from both sides

-2y = 10 - 5x

Rearrange

-2y = -5x + 10

divide both sides by -2 to isolate y

y = (5x/2) + (10/-2)

y = (5/2)x - 5
