Answer:

16

Step-by-step explanation:

Each could be watched in the places of 1,2,3 or 4. So each movie has 4 places it could be. Since you rented 4 movies you would do 4x4 which equals 16.

Step-by-step explanation:

Expressing ratios in fractional form, then

[tex]\frac{a}{c}[/tex] = [tex]\frac{a}{b}[/tex] × [tex]\frac{b}{c}[/tex] = [tex]\frac{2}{3}[/tex] × [tex]\frac{5}{6}[/tex] = [tex]\frac{1}{3}[/tex] × [tex]\frac{5}{3}[/tex] = [tex]\frac{5}{9}[/tex]

That is a : c = 5 : 9

Answer:

Step-by-step explanation:

9) a = 2 ; b = 6

a) a + b =  2 + 6 = 8

b) b - a = 6 - 2 = 4

c) ab = 2 * 6 = 12

10) c = 12 ; d = 4

a) c ÷ d = 12 ÷ 4 = 3

b) c + d = 12 + 4 = 16

c) c - d = 12 - 4   = 8

Answer:

7/30

Step-by-step explanation:

5/6-3/5 ,the LCM of denominators 6 and 5 is 30 ,6 denominator divided by 30 the result from the LCM times 5 the numerator is =25, 5 denominator divided by 30 the result from the LCM times 3 is =18 ,then subtract 25 from 18 giving you 7 ,then 7/6 or seven divided by six is one whole number, one over six

Answer:

Tessa's expression is false because -7 times -4 is positive 28, not -28.

Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)

Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.

2-21x+28

The equivalent expression for the given expression is 2-21x+28.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Tessa:

2-7(3x-4)=2-21x-28

Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.

Bernette:

2-7(3x-4)=-5(3x-4)

Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4

Lucy:

2-7(3x-4)=2-21x+28

Lucy's equivalent expression is correct.

Therefore, the equivalent expression is 2-21x+28.

Answer:

A. the slope value is 1/4

B. 0

C. y = 1/4x

Step-by-step explanation:

A: the slope can be calculated with the formula

[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]

m is the slope

(x1, y1) is your first coordinate point (any point will work)

(x2, y2) is your second coordinate point (any point will work)

Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - 0}{4 - 0} = \frac{1}{4} [/tex]

B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.

C:

the equation of the graph is y = mx + b.

m is the slope = 1/4

b is the y-intercept = 0

Therefore the equation is y = 1/4x

Answer:

25

Step-by-step explanation:

The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

Answer:

  b = 20/7

Step-by-step explanation:

The slope of the first line can be found by solving for y:

  by = -5x +6 . . . . . . add 6-5x

  y = -5/b +6/b . . . . . divide by b

The slope is -5/b.

The slope of the second line can be found by solving for y:

  7y = 4x +7

  y = 4/7x +1 . . . . . . divide by 7

The slope is 4/7.

For the lines to be perpendicular, the product of these slopes must be -1:

  (-5/b)(4/7) = -1

  -20/(7b) = -1 . . . . simplify

  b = 20/7 . . . . . . . multiply by -b

The lines will be perpendicular when b = 20/7.
