X-3.5= -3.1 I'm confused​

Answers

Answer 1

Answer:

See Below

Step-by-step explanation:

First, isolate x. To do that add 3.5 to each side

x - 3.5 =  -3.1

  +3.5    +3.5

x= 0.4

Answer 2

Answer:

X = 0.4

Step-by-step explanation:

X-3.5= -3.1  add 3.5 each side.

X = 3.5 - 3.1 simplify

X = 0.4   done!

Victoria is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additional price per minute of usage. It is known that the total charge to use a computer for 5 minutes would be $6 and that the additional rate per minute of use is $0.60. Write an equation for C,C, in terms of t,t, representing the total cost of using a computer for tt minutes at the internet cafe.

Answers

           

Step-by-step explanation:

Given that the initial charge/fee for the first 5 minutes is $6

and also the additional rate per minutes is $0.6

we can model the total charges after the equation of a straight

that y= mx+c

now using the required notation

C= 0.6t+ 6

comparing this with the equation of a straight line

the constant term c is $6 flat rate for the first 5 minutes

the gradient 0.6 is m

the dependent variable x is t

and the cost C is y  

Answer:

i believe its c=0.60t+3

Cheryl wants you find the number of hours 7th graders do work at home each week. There are 297 boys and girls in 7th grade, Cheryl random surveyed 50 girls in the entire school to find a number of our 7th graders do homework each week described why she would get a biased sample​

Answers

Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.

(FULL CREDIT TO maksimylian, I DID NOT WRITE THIS ANSWER)

Answer:

Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample.

The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population.

The results would not be a representative sample of the population.

#6 is 17 days

Step-by-step explanation:

This is how I answered it

1) 2750 = 550 + 125x

2) subtract 550 from each side

2750-550=2200

so the left over equation is:

2200 = 125x

3) divide each side by 125 to get x by itself

2200÷125= 17.6

4) you are left with: x = 17 days

The solution to the given expression is -8 - 2r - p² - 6r² which is determined by performing the arithmetic operation.

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The given expression is given in the question

(10 – 7r - p²) + (-6r² - 18 +5r)

Open the parentheses and rearrange the terms,

10 - 18 - 7r + 5r - p² - 6r²

Apply the arithmetic operation in the likewise terms,

-8 - 2r - p² - 6r²

Therefore, the solution to the given expression is -8 - 2r - p² - 6r²

Answer: So what my teacher always told me to do was act like a fraction was a tree. The tree always falls to the left which then outs the fraction as a division problem. You solve the division problem

Step-by-step explanation:

Ok so for example, lets use [tex]\frac{1}{2}[/tex]. Drawing it as a tree it then falls to the left. Therefore it becomes 1 ÷ 2. So 2 can not go into one therefore you need to put a decimal point at the top and add a zero behind the 1 under the bar. The 1 then becomes a 10, therefore 2 can go into 10 5 times. However the answer is not 5. You have to remember to bring the decimal point that you placed before the 5. In conclusion hte answer is .5 . This may be confusing because I am not able to include any photos but hopefully you'll get the point.

Edgenuity’s sample response for this question:

Sublimation occurs because the atoms in a solid must gain enough energy to form a gass without passing through the liquid state. Low air pressure and large amounts of energy, often in the form of heat, allow the atoms to move fast enough to overcome the attractive forces between them.

If you need an original response here’s my take!!:

Sublimation happens when a solid turns directly into a gas. For this to happen, there must be low air pressure and immense heat energy. This allows atoms to quickly move and perform sublimation.

We know the line segment stretches from one to 15, meaning there are 14 points on the line as there is (1,2,3, etc.)

14/2 obviously equals 7, so just plug it in from there.

12 is too far up on the line to be less than half, so (12, 3) is wrong

^ this goes for (9, 3) as well

7 is literally the halfway marker, so there is no way it could be (7, 3)

Making the answer (4, 3) because not only is it the last one remaining but it makes the most sense, being less than one half of the segment
