A bowl contains a total of 26 blue and red marbles. There are two more red marbles than
blue marbles. How many blue marbles are in the bowl?
Which of the following let statements should you use?

Let x = the number of red marbles. Let x + 2 = the number

of blue marbles.
Let x = the number of blue marbles. Let 2x = the number of
red marbles.

Let x = the number of blue marbles. Let x + 2 = the number
of red marbles.

Answer:

x is about 10.39, y is about 20.78

Step-by-step explanation:

15)

[tex]\tan 30=\dfrac{x}{18}\\x=18 \cdot \tan 30\approx 10.39\\\cos 30 =\dfrac{18}{y}\\y=\dfrac{18}{\cos 30}\approx 20.78[/tex]

Answer:

x=6√3

y=12√3

Step-by-step explanation:

This is a 30 60 90 triangle.

The side opposite from the angle 60 is x√3, which makes 18=x√3, which eventually solves to x=6√3

The side opposite from the 90 degree angle is 2x, so multiply 6√3 by 2, which is 12√3, making y equal 12√3

Answer:

30 and 9

Step-by-step explanation:

x+y=39 , x-y=21

Solve for x:

x+y=39 , x-y=21

x= 30

Substitute x with 30:

(30)+y=39 , (30)-y=21

Solve for y:

y=9

Answer:

B. 3

Step-by-step explanation:

If there are inclusion points on the numberline, then 3 is the only viable choice, as the only 2 whole numbers that can work is 2 & 3. If there is no inclusion, then none, as it will have to be a decimal (or fraction) between 2 & 3.

Answer:

25) x = 18 26) x = 50

Step-by-step explanation:

25) 108 + 4x = 180

108 + 4x = 180

-108           -108

4x = 72

x = 18

26)

101 + (x + 29) = 180

101 + 29 + x = 180

130 + x = 180

-130        -130

x = 50

Given b equals -3, determine if it is a solution to 4b - 6 = - 18.

So, we have our given which is b = -3, and we are asked to determine if it a solution to the above equation.

To do this, we can plug -3 in for b and see if it works out.

Work:

Plug in -3 for b.

4(-3) - 6 = - 18

-12 - 6 = -18

-12 - 6 = - 18

Thus, b = -3 is a viable solution for the equation of 4b - 6 = -18.

Answer:

Four less than a unknown variable- C) y-4

Quotient of a variable and four- E) z÷4

some number to the power of four- B) a^4

Four times an unknown value- D) 4x

Four more than some number- A) B+4

Step-by-step explanation:

The final answers are:

Four less than an unknown value            C) y-4

Quotient of a variable and four                E) Z/4

Some number to the power of four         B) a⁴

Four times an unknown value                  D) 4x

Four more than some number                 C) b+4

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling  the unknown value, it means we have to write y-4

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling  the unknown variable, it means we have to write

z/4

- Some number to the power of four --> this means that we have to write the power of a number, in the form , where m in this case is equal to 4. Calling  the unknown number, it means we have to write a⁴

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling  our unknown values, we have to write 4x

- Four more than some number --> this means we have to add 4 to an unknown number. Calling  the unknown number, it means we have to write b + 4

Answer:

x+9/x+1

Step-by-step explanation:

Since the denominator is the same, just add the numerator while keeping the denominator the same.

Answer: 36%; yes, the % change is equal to the percent discount

Step-by-step explanation:

Initial price = $69.99

Final price = $44.99

change in price = |(final - initial)|

change in price = |(44.99 - 69.99)|

change in price = $25

25/69.99 = x/100

100(25/69.99) = x

100(0.357) = x

35.7% = x

x = 36%

Answer:

Step-by-step explanation:

i took the test and got it right so... and do you have Mr. Hoffman

The sum of the first six terms of the following sequence is ∑(from i=1 to 6) (-10 - 3(i-1)), the correct option is A.

Lets suppose its initial term is f=a , multiplication factor is  r

and let it has total n terms, then, its sum of a geometric sequence is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

We are given that;

The sequence;  −10, −13, −16, …

Now,

The given sequence is an arithmetic sequence with first term (a1) = -10 and common difference (d) = -3.

Using this formula, we can find the first six terms of the sequence as follows:

a1 = -10

a2 = -10 + (-3) = -13

a3 = -10 + 2(-3) = -16

a4 = -10 + 3(-3) = -19

a5 = -10 + 4(-3) = -22

a6 = -10 + 5(-3) = -25

We can represent the sum of the first six terms using sigma notation as:

∑(from i=1 to 6) ai = (-10) + (-13) + (-16) + (-19) + (-22) + (-25) = -105

The sum of the first six terms of the given sequence is -105.

Using sigma notation, we can write this as:

∑(from i=1 to 6) (-10 - 3(i-1)) = -105

Therefore, by the geometric sequence the answer will be ∑(from i=1 to 6) (-10 - 3(i-1)).
