A textbook store sold a combined total of 435 psychology and sociology textbooks in a week. The number of sociology textbooks sold was 61 less than the number of psychology textbooks sold. How many textbooks of each type were sold?

Answers

Answer 1

Answer:

248 psych books, 187 soc books.

Step-by-step explanation:

x psych books were sold

x-61 soc books were sold

Total books was 435.

So -

x+x-61 = 435

2x-61 = 435

2x = 496

x = 248.

so x-61 = 187 and

248+187 = 435.

248 psych books, 187 soc books.

A triangle has an angle that measures 25. The other two angles are in a ratio of 11:20. What are the measures of those two angles?

Answers

Answer:

The measures of the two angles are 55 and 100 degrees.

Step-by-step explanation:

The three interior angles of a triangle always add up to 180.

So if one angle is 25 degrees

180 - 25 = 155

The two other angles must add up to 155.

If the ratio is 11:20

That means there are 31 equal parts between the two angles

So 155/31 =5

Whic means

11 x 5 = 55

20 x 5 = 100

The two missing angles are 55 and 100 degrees.

It should be 56, sorry if i am wrong

Step-by-step explanation:

28 divided by 14 is 2

56 divided by 14 is 4

Answer:

56

Step-by-step explanation:

First, you simplify 2/4 to 1/2. Then you figure that 28 * 2= 56/1= 56.

To double check your answer, put 56 in the box and see if the two fractions equal each other.

solve for x and b​

Answers

Answer:

2x + 60 = 4x( Vertically opposite angle)

60 = 4x - 2x

4x - 2x = 60

2x = 60

x = 60÷2

x = 30

2x + 60 + B = 180° ( Linear Pair )

2(30) + 60 + B = 180°

60 + 60 + B = 180°

120 + B = 180°

B = 180° - 120

B = 60

Turn both equations into slope-intercept form [ y = mx + b ].

x + 3y = 3

~Subtract x to both sides

3y = 3 - x

~Divide 3 to everything

y = 1 - x/3

~Reorder

y = -1/3x + 1

4x + 3y = -6

~Subtract 4x to both sides

3y = -6 - 4x

~Divide 3 to everything

y = -2 - 4x/3

~Reorder

y = -4/3x - 2

Graph of the equations will be shown below. Note that the solution of graphing two equations will be where both equations intersect. Both lines intersect at (-3, 2), hence making that the solution.
