Is x = 7 a solution to the equation 3x - 4 = 15? No Yes

Answers

Answer 1

Answer:

no

Step-by-step explanation:

To determine if x = 7 is a solution.

Substitute x = 7 into the equation and if left side equals right side then it is a solution

3(7) - 4 = 21 - 4 = 17 ≠ 15

Then x = 7 is not a solution to the equation

Answer 2

No, x = 7 is not the solution of Equation 3x - 4 = 15

What is an Equation?

An Equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that an Equation 3x - 4 = 15

Solving x = 7 we get,

3*7 - 4 = 21 - 4 = 17

17 ≠ 15

Hence, x = 7 is not a solution of the given Equation.

Answer:

If Angle A and Angle B are vertical angles,

what is value of x?

D. 8

If Angle A and Angle B are supplementary

angles, what is measure of

Angle B?

D. 140

Step-by-step explanation:

If Angle A and Angle B are vertical angles,

what is value of x?

Vertical angles are congruent thus

40° = 5x°

5x° = 40°

(5x / 5)° = (40 / 5)°

x° = 8°

If Angle A and Angle B are supplementary

angles, what is measure of

Angle B?

Supplementary angles add up to 180° or a straight line.

180° – 40° = 140°

Find Thin Mints in radians

Need help with math homework

Answers

Answer:

a) Thin mints = 1.885 radians

b) Savannah smiles cookies = 0.332 radians

Step-by-step explanation:

To convert an angle from degree to radians, the formula is given as :

x ° × π/180 = radians

Where x = angle to be converted

From the diagram we are to convert Thin mints and Savannah cookies to radians

a) Thin mints = 108°

Converting to radians

= 108° × π/180

= 1.8849555922 radians

Approximately = 1.885 radians

b) Savannah smiles cookies = 19°

Converting to radians

= 19° × π/180

= 0.331613 radians

Approximately = 0.332 radians

What is Right triangle?

A triangle in which one of the interior angle is 90° is called a right triangle.

Given that;

Sides of a right triangle are 12, 9 and x.

Now,

By the Pythagoras theorem;

x² = 12² + 9²

x² = 144 + 81

x² = 225

x = √225

x = 15

Thus, The value of x is 15.

Given the following functions f(x) and g(x), solve
below:
(f/g)
(-5) and select the correct answer
f(x) = 2x - 20
g(x) = x - 1

05
0
-5
30

Answers

Answer:

-5

Step-by-step explanation:

Given the functions

f(x) = 2x - 20

g(x) = x - 1

f(x)/g(x) = 2x - 20/x-1

f/g(x) = 2x - 20/x-1

Substituting x = -5 int the result

f/g(5) = 2(5) - 20/5-1

f/g(5) = 10 - 20/4

f/g(5) = -10/4

f/g(5) = -5

Hence the result is -5

A square has a diagonal that is 26 feet long.
What is the perimeter of this square?

Answers

answer:

52[tex]\sqrt{2}[/tex]

step-by-step explanation:

we can use the 45-45-90 triangle theorem for this: x, x, x[tex]\sqrt{2}[/tex]

this is because this is a square

squares have two sides of the same length, and the diagonal is differentthe x's stand for the sides, whereas the x[tex]\sqrt{2}[/tex] stands for the diagonal

x[tex]\sqrt{2}[/tex] = 26

x = 13[tex]\sqrt{2}[/tex]

now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4

13[tex]\sqrt{2}[/tex] X 4 = 52[tex]\sqrt{2}[/tex]
