what is the x of 3x+39=90

Answer:

Step-by-step explanation:

Lets look at the expressions with respect to the competition parameters: Expressions:You Y =3m+13Friend(F)=4m+6 1.  The competition begins AFTER you and friend already caught some flies.  This would be represented by the CONSTANT terms in each expression (in this case, 13 for you, 6 for friend). So the number of flies caught BEFORE THE COMPETITION would be   13+6=19 flies total  2.  The competition length was "m" minutes long when flies are caught and counted.  This would be represented by the VARIABLE terms in each expression (in this case, 3m for you, 4m for friend).  We are not given a numeric value for the variable "m" to evaluate. So the number of flies caught DURING THE COMPETITION (timed "m" minutes long) would be 3m+4m=7m flies total ...and the number of flies per minute would be calculated as 7m÷m=7 flies per min....total #flies divided by total minutes 3.  If the problem asked for the total number of flies caught by you and friend, before and after the competition 7m+19 flies total add like terms in each expression.

Answer:

M = 3

3 x 3 + 13 = 22

E = 2S is the equation that links the base's S number of sides to its F number of faces.

E = 2S

S is the number of sides on a base.

E equals the number of edges.

Triangle (1)

3 and S are the base side counts.

edges equal 6, hence the answer is E.

E = 2S

Table 2

Base has four sides, hence the response is S.

edge count = E (8 edges)

E = 2E

3rd Pentagon

S is equal to the five sides of the base.

The letter E is equivalent to 10 edges.

S = 2E

4) A hexagon

S is equal to the six sides of the base.

Edge count: 12 equals E.

E = 2S

Thus, it is shown that E = 2S.

The 30 sides of the pyramid foundation.

The answer is S since the base has 20 sides.

The number of edges is E = 2S = 20 x 2 = 40 edges.

7-(-4) is 4 units from 7 in the negative direction.

The number line keeps going both ways. You can include 6, 7, and so on, all the way up to the hundreds, thousands, and beyond, because the set of natural numbers only extends to the right.

A number line is a diagram that shows numerical values along a straight line that can be drawn either horizontally or vertically. It's simple for us to compare and compute basic arithmetic operations on numbers when they are written down on a number line. A number line's origin is typically thought to be zero (zero). There are only positive numbers to the right of zero and only negative numbers to the left of zero.

therefore,

7 - (-4)

= 7 + 4

= 11

when we simplify the expression we get the answer as 11 units

the result is that 11 units is 4 units away from 7 in a negative direction.

Hence we get the complete sentence.

The simplification by combining like terms of 7s -s  is 6s.

According to the given question.

We have an expression 7s - s.

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression

7s - s.

Here 7s and s both are the like terms.

So, we subtract coeffcients of s to simplify the given expression.

Therefore, the simplification of the expression 7s - s is given by

7s - s

= 6s

Hence, the simplification by combining like terms of 7s -s is 6s.

The equation for this line in standard form is 2x + y = 10.

These are two methods for finding the equation of a line given a point and slope. Create the equation y = mx + b using the m given in the problem and the b you just solved. Point-slope form = y-y1 = m (x-x1), where (x1, y1) is the specified point and m is the specified slope. "x" and "y" remain as variables.

The slope is m=(-A / B).

A line with a slope of (-2) has the following equation:

2x+y=C Finding the constant C requires a point. Use (2,6)

2(2) +6 = C

10 = C

The GCF of a number is the greatest common factor of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder.

The numeric values of the function f(x) = 5x - 7 are given as follows:

a) f(-2) = -17.

b) f(1/2) = -9/2.

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is not 100% visible from the picture, but we are going to suppose it is given by:

f(x) = 5x - 7.

At x = -2, the numeric value is:

f(-2) = 5(-2) - 7 = -10 - 7 = -17.

At x = 1/2, the numeric value is:

f(1/2) = 5(1/2) - 7 = 5/2 - 14/2 = -9/2.

The equation of line is y = (-2/3)x + 5

Given the points:

(x₁, y₁) = (0, 5)

(x₂, y₂) = ( 3, 3)

The slope-intercept form:

y = mx + b

Where, m is the slope and b is the y-intercept, that is (0, b)

The formula for slope:

m = (y₂ – y₁) / (x₂ – x₁)

We have given

x₁ = 0

x₂ = 3

y₁ = 5

y₂ =3

So,

m = (3 – 5) / (3 – 0) = -2/3

here, we have b = 5

Therefore we have the equation of the line as:

y = mx + b

The arithmetic mean a n of the given terms a n₋₁ = r, a n₊₁=s is

a n₋₁ = r, a n₊₁=s is

[tex]a_{n}[/tex] = [tex](a_{n+1} - a_{n-1})/2[/tex]

The arithmetic mean is the most straightforward and widely used method of calculating a mean or average. It only requires adding up a group of figures, then dividing the result by the entire amount of figures in the series. Consider the numbers 34, 44, 56, and 78 as an example. It totals 212.

The mean or arithmetic average are other names for the arithmetic mean. It is determined by adding up each number in a particular data set, then dividing the result by the overall number of items in the data set. For uniformly distributed integers, the middle number serves as the arithmetic mean (AM).

Answer:

You will  need 12.5 gallons of the 22% salt solution and 7.5 gallons of the 38% of the salt solution

Step-by-step explanation:

.22x + .38(20 -x) = .28(20)  I want to clear the decimal, so I will multiple through by 100

100[.22x + .38(20-x)] = [.28(20)]100

22x + 38(20-x) = 28(20)  Distribute the 38

22x + 760 -38x = 560 combine the x's

-16x + 720 = 560 Subtract 720 from both sides

-16x = -200  Divide both sides by -16

x = 12.5

The given list is a finite series.

There are two parts to our question.

In the first part of the question, we are asked whether the given list of numbers is a sequence or a series.

To answer this part, we should be familiar with what the concept of sequence and series.

A sequence is a plain list of numbers.

A series is a sum of numbers in the list.

The given list looks something like this,

5+10+ . . . . . . +25

So, considering the given definitions of both sequence and series we can clearly tell it is a series.

Now up to the second part of the question, is the given series finite or infinite?

We know this is finite because it has a start of 5 and an end of 25. There's an ellipsis in the middle, but it has a beginning and an end, so this will be the right answer.

Probability is the degree to which an occurrence is likely to take place, as determined by the proportion of favorable examples to the total number of instances for which it is probable to have occurred.

Let's assume

1 - P(no one has the same sign) >= 0.5

P(two or more people have the same sign) = 1 - P(no one has the same sign)

= 1 - (12 / (12-n)) / 12^n

1-0.5=0.5 >= P (no one has the same sign) = 12/(12^n x (12-n))

0.5 >= 12 /(12^n x (12-n))

Number of cards in each of the boxes

First box =17 cards

Second one box=21 cards

Third one box =22 cards

Fourth one  box=16 cards

Now let find the best  best estimation for the total number of baseball cards:

Total number of baseball cards=17+21+22+16

Total number of baseball cards=20+20+20+20 (rounded to the nearest tens)
