Answer:

x = 2

Step-by-step explanation:

2(x - 1/2) = 3(5 - 2x) (distribute 2 and 3)

2x - 1 = 15 - 6x (add 6x on both sides)

8x - 1 = 15 (add 1 on both sides)

8x = 16 (divide both sides by 8)

x = 2

CHECK

2(2 - 1/2) = 3(5 - 2(2)) (solve what's in parenthesis)

2(1.5) = 3(1) (distribute)

3 = 3

Answer:

Step-by-step explanation:

A system of equation is a set of a number of equation used for finding their solution. The solution of the given system of equations is (2,-22). The correct answer is option 1.

A system of linear equation can be defined as a number of equations needed to find the solution. On the basis of the number of solutions a set of equations can be called either consistent or inconsistent.

The given equations are

y = -6x -10 and y = -1/2x -21

They can be rewritten as,

y + 6x = -10 ------------------- (1)

2y + x = -42 ------------------- (2)

To get the value of x ,

(2y + x) - 2(y + 6x) = -42 - 2×(-10)

=> -11x = -22

=> x = 2

Substitute x = 8 in equation (1) to get y,

y = -10 - 12

y = -22

Hence, the solution for the given system of equation is (2,-22).

Answer:

b and d I think are both right but if you can only pick one go with B

The measure that could be the side lengths of a right triangle is 30 cm, 72 cm, 78 cm, the correct option is B.

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.

We are given that;

The right triangle

Now,

We can use this equation to test each option by plugging in the values and checking if they satisfy the equation.

A. 7 cm, 21 cm, 25 cm

7^2 + 21^2 = 25^2

49 + 441 = 625

490 = 625

False

This option does not satisfy the Pythagorean theorem, so it cannot be the side lengths of a right triangle.

B. 30 cm, 72 cm, 78 cm

30^2 + 72^2 = 78^2

900 + 5184 = 6084

6084 = 6084

True

Therefore, by right angle triangle the answer will be 30 cm, 72 cm, 78 cm.

Answer:

x=32

Step-by-step explanation:

1. Find the angle next to the 122

Since it is a 180 degree total angle, you subtract 180-122 to get 58 degrees

2. You know two out of the 3 angles now because the square indicates a 90 degree angle. So you add 90 + 58 = 148

3. Since the total amount of degrees in a triangle is 180, you subtract 180-148 to get 32 degrees

not sure what your question is but if youre trying to solve for the system of equations your awnser is (5,3/2)

Answer:

x= 5, y= 3/2

Step-by-step explanation:

5x -4y =19 (Equation 1)

x+ 2y=18 (Equation 2)

Using substitution method,

From equation(2),make x the subject of formula

x= 8-2y (Equation 3)

Substitute equation 3 into equation 1

5x -4y= 19

5(8-2y) -4y = 19

40 -10y -4y = 19

40-14y=19

Collect like terms

40-19=14y

21=14y

y= 21/14 = 3/2

Substitute for y in equation 3

x= 8 -2y

   8- 2(3/2)

  =8 -3

Answer:

a = 9r²

Step-by-step explanation:

Given

r = [tex]\frac{\sqrt{a} }{3}[/tex] ( multiply both sides by 3 to clear the fraction

3r = [tex]\sqrt{a}[/tex] ( square both sides )

(3r)² = ([tex]\sqrt{a}[/tex] )²

9r² = a

The equation that could be used to determine x is ([tex]x^{2}[/tex] + 8x - 308).

As per the question, the small integer is x. So, the large integer will be (x + 8).

Also, the question mentions that their product is 308. Representing the given information in mathematical equation form -

x (x + 8) = 308

Performing multiplication on Left Hand Side of the equation

x² + 8x = 308

Shifting 308 from Right Hand Side to the Left Hand Side of the equation. the equation that will form is -

x² + 8x – 308 = 0

On solving this quadratic equation, we will get the negative numbers, which will validate our formed equation.  

x² + 8x – 308 = 0

x² + 22x - 14x – 308 = 0

x (x + 22) - 14 (x + 22) = 0

(x + 22) (x - 14) = 0

x = -22 and 14

Since the numbers are negative, hence, value of small number is -22.

Large number = -22 + 8

Large number = -14

Thus, the small and large number is -22 and -14.

Therefore, the correct equation is x² + 8x – 308 = 0.

The value of x as evident in the task content is; 14 and hence, the measure of angles m<DEC and m< CEF are; 142° and 38° respectively.

It follows from the task content that the justifications of the statements are to be indicated.

On this note, the justifications are as follows;

Hence, the measure of angle; m<DEC = 11x -12.

= 11(14) - 12
