Answer:

x = -5

Step-by-step explanation:

12x - 3x + 4 = 5x - 16

9x + 4 = 5x - 16

9x - 5x = -4 - 16

4x = -20

x = -5

Identify two numbers less than 20 with the most factors
Anastaziya [24]

<u>Answer</u>

18 and 12


<u>Explanation</u>

Factor is a number or algebraic expression that divides another number or expression evenly that is with no remainder.

Odd number have few factors so the can't be the answer.

WE are going to try the even numbers.

18 ⇒ 18, 9, 6, 3, 2, 1

16 ⇒ 16, 8, 4, 2, 1

12 ⇒ 12, 6, 4, 3, 2, 1

10 ⇒ 10, 5, 2, 1

Other number less than 10 has factors less than 5.

It can be seen from above that 18 and 12 have the most factors.

PLEASE HELP GEOMETRY Use the word bank to help you with possible answers (there are extra options that are not to be used)
Mekhanik [1.2K]
Short Answers:

Answer for part A: Given
Answer for part B: Angle A = Angle D (not sure why this isn't in word bank?)
Answer for part C: ASA
Answer for part D: BC = EF
Answer for part E: CPCTC

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

Explanations:

Part A:

AB = DE is given at the very top of the problem. So we simply say "given". We always repeat what we are given at the very start of the proof. You can see this for lines 1 through 3, which are repeating the three givens. 

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

Part B:

The three givens are:
AB = DE
angle A = angle D
angle B = angle E
the first and last of this trio is used (for statements 1 and 3 respectively). So the only thing left is "angle A = angle D"

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

Part C:

We're using ASA (angle side angle) because we're given two pairs of congruent angles. The side for each triangle is between the two angles. See the attached diagram for more info.

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

Part D:

For any proof, you will ALWAYS have the last statement be the thing you want to prove. In this case, we want to prove BC = EF. 

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

Part E:

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent"

If the two whole triangles are congruent, then the smaller corresponding parts that make up the triangles must be congruent as well.

This is science just please look at the pic and answer if you know don’t answer if you don’t know don’t steal points
STatiana [176]

Answer:

1) a body of air with horizontally uniform temperature, humidity, and pressure.  

2) the foremost part or surface of anything. the part or side of anything that faces forward: the front of a jacket.

3) A cold front is often associated with showers and thunderstorms. As it advances, often quite rapidly (50 to 65 km [30 to 40 miles] per hour), the cold air, which is relatively dense, undercuts the displaced warm air, forcing it to rise.

4) Cold Fronts. When a cold front passes through, the weather becomes significantly colder and drier. (It isn't uncommon for air temperatures to drop 10 degrees Fahrenheit or more within an hour of a cold frontal passage.) The weather map symbol for a cold front is a blue curved line with blue triangles.

5) When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. Symbolically, a cold front is represented by a solid line with triangles along the front pointing towards the warmer air and in the direction of movement.

Step-by-step explanation:

Joey has 24 coins in his pocket. The coins are all nickels and dimes. The total value of the coins is $1.85. How many dimes does
Virty [35]

Answer:

Your system of equation:

n + d = 24

5n + 10d = 185

Step-by-step explanation:

Let:

nickels = $0.05; amount of dimes = n

dimes = $0.10; amount of dimes = d

There are 24 coins in all:

n + d = 24

Note the amount each coin is worth. The total value is $1.85

0.05n + 0.10d = 1.85

Move the decimal point to the right for each term.

0.05n = 5n

0.10d = 10d

1.85 = 185

5n + 10d = 185 is your new equation.

Your system of equation:

n + d = 24

5n + 10d = 185
