Answer:

Symmetric property

Step-by-step explanation:

In this question, we are given a set of options to choose the correct answer from which gives the definition of the property in the question.

The correct answer here is the symmetric property. So why is this correct?

In proper terms, we refer to this property as the symmetric property of congruence.

It is a way of referring to the fact that when writing the way two congruent angles are equal to each other by the property of congruence, we can move in either of the two directions.

Either way we write, we are absolutely correct to indicate that both angles are equal due to the property of congruence.

If you want to evaluate what percent of 550 is 4, you can do this in two following steps.<span>
<span>First, you have to write it as a fraction: 4</span>/550.
Second, you have to transform this fraction to percent: (4/550)*100%.

(4/550)*100% = 0.0072727272727273*100% = 0.727%

A youth group sells cookles for $8 a boxIf they spent 1000 buying the cookies, which equation below shows the profit () made by
Sonbull [250]

Answer:

D)        P = 8b - 1000

Step-by-step explanation:

Think about it,

First off

    If they spent 1000 from just buying the cookies. When you buy something you lose money. So that's -1000.

Secondly,

     If they charged $8 per box that would cost an additional eight dollars each time a cutomer perchased a box. Another way to show addition is multiplication.

Ex if someone bought 7 box and 8 dollars each it could be shown as either:

1. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7

2. 8 + 8 + 8 + 8 + 8 + 8 + 8

3.  7 x 8  or 8 x7                                                                                                                      

So 8b - 1000 would make the most sense.

0.6( 10n + 25 ) = 10 + 5n
Doss [256]

Answer:

n=−5

Step-by-step explanation:

0.6(10n+25)=10+5n

Step 1: Simplify both sides of the equation.

0.6(10n+25)=10+5n

(0.6)(10n)+(0.6)(25)=10+5n(Distribute)

6n+15=10+5n

6n+15=5n+10

Step 2: Subtract 5n from both sides.

6n+15−5n=5n+10−5n

n+15=10

Step 3: Subtract 15 from both sides.

n+15−15=10−15

n=−5

an engineer estimates that 30% of gasoline is used efficiently by a car. how many gallons,out of 20 gallons, are used efficientl
juin [17]

We need to find 30% of 20 gallons.

1) We can write a proportion

20 gallons ---- 100%

x gallons --------30%

x = 20*30/100 = 6 gallons

2) Or we can write 30% as decimal.

30% = 30/100 = 0.3

0.3 of 20 = 0.3*20 =6 gallons

Answer 6 gallons are used efficiently.
