DIA [1.3K]

Answer:

5x+3
x -7
-x +7

Step-by-step explanation:

Combine like terms. The associative and commutative properties of addition apply, as does the distributive property.

__

1. (2x+5)+(3x-2) = (2x +3x) +(5 -2) = 5x +3

__

2. (3x-2)-(2x+5) = 3x -2 -2x -5 = (3x -2x) +(-2 -5) = x -7

__

3. (2x+5)-(3x-2) = 2x +5 -3x +2 = (2x -3x) +(5 +2) = -x +7

_____

<em>Additional comment</em>

Note that swapping the order of operands in a subtraction problem (problems 2 and 3) will cause the sign of the result to reverse.

laurens suv was detected exceeding the posted speed limit of 60 kilometers per hour , how many kilometers would she have been tr

Vlada [557]

Answer:

60 kilometers per hour (kmph) over the limit

Step-by-step explanation:

The speed limit is 60 kmph

Let's find his original rate:

We know D = RT

Where

D is the distance, in km

R is the rate, in kmph

T is the time in hours

He went 10 km in 5 minutes, so we need the time in hours, first. That would be:

5/60 = 1/12 hour

So, putting into formula, we find rate:

D = RT

10 = R(1/12)

R = 10/(1/12)

R = 10 * 12

R = 120 kmph

He was going over by:

120 - 60 = 60 kmph

a parking meter contains $8.25 in dimes and quarters. after emptying the meter, the worker counts 51 coins. how many quarters an

Marianna [84]

<h3>30 dimes and 21 quarters are present</h3>

<em><u>Solution:</u></em>

Let "d" be the number of dimes

Let "q" be the number of quarters

1 dime = $ 0.10

1 quarter = $ 0.25

The worker counts 51 coins

Therefore,

d + q = 51

d = 51 - q ---------- eqn 1

<em><u>A parking meter contains $8.25 in dimes and quarters</u></em>

Therefore,

0.10d + 0.25q = 8.25 -------- eqn 2

<em><u>Substitute eqn 1 in eqn 2</u></em>

0.10(51 - q) + 0.25q = 8.25

5.1 - 0.10q + 0.25q = 8.25

0.15q = 3.15

Divide both sides by 0.15

<h3>q = 21</h3>

Substitute q = 21 in eqn 1

d = 51 - 21

<h3>d = 30</h3>

Thus 30 dimes and 21 quarters are present

Use 3.14 for pi to estimate the area of a circle. The diameter is given. Round your answer to the nearest hundredth if necessary

Colt1911 [192]

221.56, because in order to get the area of a circle, you must use this formula: area = (pi divided by 4) x diameter squared.

In this case, area = (3.14 / 4) x (16.8 x 16.8)
