Answers

x = 11

Step-by-step explanation:

=> 11x + 2 = 5x + 10 + 58

=> 11x - 5x = 10 + 58 - 2

=> 6x = 66

=> x = 66/6

=> x = 11

We are asked to solve the equation [tex]\large\pmb{11x+2=5x+10+58}[/tex].

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]

The goal is to get x all by itself.

So here's how we solve the equation...

///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\

Notice that we can add 10 and 58 right off the bat:

[tex]\large\pmb{11x+2=5x+68}[/tex]

Now we subtract 2 from both sides of the equal sign:

[tex]\large\pmb{11x=5x+66}[/tex]

Now we subtract 5x from both sides of the equal sign:

[tex]\large\pmb{6x=66}[/tex]

Divide both sides by 6:

[tex]\large\pmb{11}[/tex]

That's the value of x.

Hope it helps you out! :D

Divisible rule of 6 is " The number must be divided by 2 and 3 " so answers are 774810,774840,774870.

Step-by-step explanation:

can someone explain how to do this, I don't want the answer?

Answers

The table is filled out by following these steps:

Step 1) Pick any number you want for x. Usually small values work such as x = 0, but you can choose anything you want. Be sure it fits within the window of the graph.Step 2) Replace x with that number you picked. If you picked x = 0, then y = (1/3)x becomes y = (1/3)*0 = 0. Meaning x = 0 leads to y = 0. The point (0,0) is on the graph.Step 3) Go back to step 1 and repeat the process with other x values. I recommend picking multiples of 3 so you can avoid fractional values of y.

Follow those steps listed above so you can fill out the table. Each row of the table generates a different (x,y) point on the graph. Then draw a line or curve through the points. In this case, it's a straight line.

This straight line has a slope of 1/3 because y = (1/3)x is in slope-intercept form y = mx+b where,

m = 1/3 = slopeb = 0 = y intercept

A slope of 1/3 means "go up 1, over to the right 3" when hopping from point to point along the line.

The unit rate and slope are the same thing when it comes to linear equations.

You have the slope already, you need to find the unit rate with the slope, you just have to put 1/3 in the graph and use rise/run

Find the volume of the cone. Round to two decimal places

Answers

Answer:

564.44

11*7 squared

Answer:

V = 564.15 ft^3

Step-by-step explanation:

The formula for the volume of a cone of base radius r and height h is

V = (1/3)(pi)(r^2)(h). Here, r = 7 ft and h = 11 ft, and so the volume of this particular cone is

V = (1/3)(3.14)(7 ft)^2*(11 ft), or V = 564.15 ft^3

A book store is hosting a special night in which families can enjoy a story and craft time. Tickets to the
event must be purchased ahead of time and are $1.50 for children and $2.50 for adults. So far, 45
children's tickets have been sold, which is 60% of the total tickets sold. How many tickets have been
sold so far? Show your calculations or explain how you got your answer.

Answers

Answer:

75 total tickets

Step-by-step explanation:

METHOD 1:

We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.

So, basically, we solve for x:

We have, 60% × x = 45

or, 60/100 × x = 45

Multiplying both sides by 100 and dividing both sides by 60,

we have x = 45 × 100/60

x = 75

If using calculator, enter 45x100/60, which will give you the answer.

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

METHOD 2:

Division is the opposite of multiplication

Start with the formula to calculate the percentage of total

y=value÷ percentage/100

Substitute values in the equation

y=45÷60/100

Simplify and solve

y=45÷0.6

y=75

Both methods give you 75, therefore 75 tickets have been sold

So your supposed to do 1.50/1 x 60% which is 90

The amount of sports drink in a cooler during practice is modeled by the equation y = 648 -24x

y = the number of ounces in the cooler after practice
x = the number of players at practice who take drinks from the cooler

What does the Y-INTERCEPT mean?

Answers

When x is 0 what’s the y , is that what u r asking

The answer would be C. Because it is asking what the Y intercept means. They tell us y= the number of ounces in the cooler after practice. We do not know how much the kids drank, but they do tell us X=the number of players who take drinks from the cooler. Since the question is 24X we can assume the 24 means the amount the students drank. If we solved that, we would know how much was left after practice which is what Y is asking us. So the answer is C because it tells us what the Y intercept means (Each person drank approximately 24 OZ of water at the practice. 648-24x)

Vowels include AEIOU, so in the first box there is 2 vowel out of the 5 letters so 2/5 probability for the first box. Box 2 includes 2,4,6,8 as the even numbers out of the 9 numbers so 4/9
If you were solving the probability for each box individually that would be your answer
However if you are doing statistics and need to do it in a certain order you multiply the fractions
2/5 x 4/9 = 8/45
(.17777)
This leaves you with a 17% (8/45) chance of picking a vowel then an even number.

the probability of getting a vowel is 2/5 because a vowel is A E I O U and sometimes Y, and there’s 2 vowels out of 5 letters

Box 2 would be 4/9
