Answer: x=5

Let’s start by rewriting the equation

4x=3x+5

Let’s combine like terms- 4x and 3x. We’ll do this by subtracting 3x on both sides.

x=5

This is your answer! Hope this helps comment below for more questions :)

Help. Geometry. Branliest!!

1. Correct. The reflection happens over segment AB and then you translate 6 units to the right and 3 units up. This will move point A to D, B to F, C to E, to have the triangles line up perfectly.

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

2. Problem 1 already confirmed the triangles are congruent based on how they line up perfectly. Another way to prove this is to either use the SAS (side angle side) or LL (leg leg) theorem. With SAS, we need a pair of congruent sides and a pair of angles, with the angles between the two sides. The horizontal and vertical sides can be easily measured. The angles between the two sides are 90 degree angles. Because we have right triangles, we can use LL which is really just a special case of SAS.

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

3. Segment EF is 5 units. You can use the pythagorean theorem with a = 3 and b = 4 to solve a^2+b^2 = c^2 to get c = 5. Or you can use the fact that BC = 5 is given to us, so EF must also be 5 as well. This is because of the idea that if two triangles are congruent, then their corresponding pieces must be the same as well.

Real world example: imagine having 2 houses that are perfect clones of each other. If this is the case, then surely their front doors would be identical copies as well. In this analogy, a house is a triangle, while the front door is the segment.

A) What is the population of interest? Approximately, how many people are in the population of interest? (Recall, the definition

salantis [7]

The What is the population of interest are:

GMC students
People who own Cars in Macon, GA.
People who eat oatmeal in Georgia.

The data collection method according to the group below

Survey
Survey
Experiment

<h3>What is the statistical studies about?</h3>

The best data collection method for the first one oatmeal and GMC students is survey because the population is large and opinions may differ.

The best data collection method for the cars is Experiment as one needs to study the cars that pass the red lights

For one of the three studies, a census is possible in the first one because the study population is the Georgia which is very large.

For the two studies the one that a census is not needed is GMC students and cars at red light because the population is not too big.

Based on the study I will use 500 people, 200 students, or 300 cars and the sampling technique would be Systematic sampling, Simple random sampling and Judgmental/purposive sampling.

A Simple random sampling is known to be the easiest method of selecting a sample as every member is known to have an equal chance of being selected in the sample.

See the other part of the question below

Consider the following statistical studies:

1. A study (in Georgia) of the effect of eating oatmeal on lowering cholesterol.

2. A study of current GMC students next career move after graduating or transferring from GMC.

3. A study of how many cars run the red light at a certain intersection in Macon, GA.

Abby and Annie have the same number of coins.

svetlana [45]

Answer:

2400 coins

Step-by-step explanation:

What we should do is calculate the Least Common Multiple of 80 and 75, since each of us put together a group with this amount of coins, this way we will know the amount of coins when they are equal.

To obtain the L.C.M

you have to factor both numbers and multiply the numbers whose exponent is the highest, it looks like this:

75 = 5 ^ 3

80 = 2 ^ 4 * 5

We multiply those with the highest exponent,

5 ^ 3 = 75

2 ^ 4 = 16

75 * 16 = 1200.

L.C.M. is 1200.

Since they tell us that they have less than 2000 coins, this is the correct answer, because when assembling these groups in this way, they coincide again in 2400, which is over the limit.

So, each one has 1200 coins, in total it would be:

1200 * 2 = 2400

Between them they have a total of 2400 coins
