is the expression 5+3x/2 equal to the expression 4x

Angle B is 90 degrees so angle A and c when added also equal 90:

7x + 8 + 3x + 2 = 90

Simplify:

10x + 10 = 90

Subtract 10 from both sides

10x = 80

Divide both sides by 10

X = 8

Now you have x calculate angle A:

7x + 8 = 7(8) + 8 = 56 + 8 = 64

Answer: C. 64

Answer:

C

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , so

7x + 8 + 3x + 2 + 90 = 180 , that is

10x + 100 = 180 ( subtract 100 from both sides )

10x = 80 ( divide both sides by 10 )

x = 8

Then

∠ A = 7x + 8 = 7(8) + 8 = 56 + 8 = 64° → C

A negative value is when money is taken out ( withdrawal). A positive value is when money is added to the account(deposit)

-10.40 is a withdrawal

8.50 is a deposit

Answer:

Hint :- Withdrawal is denoted as the -ve sign and deposit are denoted by the +ve sign. This is because if we deposit money then the money increase and if we withdraw then the money decreases.

-10.40

See there is a negative sign. This means it is a withdrawal

8.50

See there is a positive sign. This means it is a deposit

Answer:

27.25$

Step-by-step explanation:

1 dozen is 12.

327$ ÷ 12 is 27. 25

Answer:

$27.25.

Step-by-step explanation:

327/12

= $27.25

Step-by-step explanation:

1/2x + 10 = 1/4x + 54 Subtract 1/4x on both sides

1/4x + 10 = 54 Subtract 10 on both sides

1/4x = 44 Multiply both sides by 4

Hi! I'm happy to help!

To solve this problem, we need to find out what part isn't already listed.

We know that The entire line (SQ) is 80, and the part of the line that isn't RS (QR) is 33.4. The rest of the line must be the difference between 80, and 33.4. To find the difference we use subtraction:

80-33.4

44.6

So, RS is 44.6

I hope this was helpful, keep learning! :D

The calculated length of the segment RS is 46.6

From the question, we have the following parameters that can be used in our computation:

R is between Q and S.

QR = 33.4 and SQ = 80

using the above as a guide, we have the following:

QR + RS = QS

substitute the known values in the above equation, so, we have the following representation

33.4 + RS = 80

So, we have

RS = 80- 33.4

Evaluate

RS = 46.6

Hence. the length of the segment RS is 46.6

Answer:

60

Step-by-step explanation:

We know that LMO = 90

2x+4x = 90

6x = 90

Divide by 6

6x/6 = 90/6

x = 15

There are generally 3 methods to solve inequalities

Step-by-step explanation:

By algebraic method

First, solve f(x) = 0. There are 2 real roots x1 = 1, and x2 = - 3.

Replace x = 0 into f(x). We find f(0) = - 3 < 0. Therefor, the origin O is located inside the solution set.

Answer by interval: (- 3, 1)

The graph of f(x) is an upward parabola (a > 0), that intersects the x-axis at x1 = 1 and x2 = - 3. Inside the interval (-3, 1), the parabola stays below the x-axis --> f(x) < 0.

Therefor, the solution set is the open interval (-3, 1)

Using the reflection concept, it is found that the function g is given by:

[tex]g(x) = |6x| - 2[/tex]

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

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

Reflecting over the x-axis:

[tex]g(x) = f(-x)[/tex]

[tex]g(x) = |6(-x)| - 2[/tex]

[tex]g(x) = |-6x| - 2[/tex]

Modulus is an even function, thus [tex]|-6x| = |6x|[/tex], and:

[tex]g(x) = |6x| - 2[/tex]

A sequence is the pattern or rule that guides the creation of a set. The most common sequence are the arithmetic and the geometric sequence.

The complete question illustrates that we build a sequence of number.

Let the n term of the sequence be [tex]T_n[/tex].

2 times 3 less than the previous number means:

[tex]T_n = T_{n-1} - 2 \times 3[/tex]

Where:

[tex]T_n \to[/tex] The current number

[tex]T_{n-1} \to[/tex] The previous number

Assume the first number starts with 0, the next numbers will be:

[tex]T_2 = 0 - 2 \times 3 = -6[/tex]

[tex]T_3 = -6 - 2 \times 3 = -12[/tex]

[tex]T_4 = -12 - 2 \times 3 = -18[/tex]

So, the sequence is:

0, -6, -12, -18.....

Assume the first number starts with 3, the next numbers will be:

[tex]T_2 = 3 - 2 \times 3 = -3[/tex]

[tex]T_3 = -3 - 2 \times 3 = -9[/tex]

[tex]T_4 = -9 - 2 \times 3 = -15[/tex]

Answer: The second number is 96.

Step-by-step explanation:

Let the second number be x

7/8 = 84/x

or, 7x = 672

or, x = 672/7

so, x = 96

Answer: The second number = 96

Step-by-step explanation:

Given information

Ratio = 7 : 8

First number = 84

Second number = x

Set proportion according to the given information

84 / x = 7 / 8

Cross multiply

7x = 84 × 8
