There was 7/8 of a pizza left over. Sally ate 1/3 of the leftover pizza. What fraction of the whole pizza did Sally eat?

Answers

13/24 because you have to multiply the denominators then the numerators by 3 and 8 so 7/8x 3/3 = 21/24 then 1/3 x8 = 8/24 then subtract 21/24-8/24= what gets you 13/24

Answer:

1 1/8 pizza (or 1 whole pizza and 1 eighth of a pizza)

Step-by-step explanation:

Answer:

m2KJL = 54°

Step-by-step explanation:

In AJKL,

MAJKL = 72°

JK = KL

Since, two sides of AJKL are congruent, triangle is an isosceles triangle.

By the property of an isosceles triangle,

Opposite angles of the congruent sides of an isosceles triangle are equal in measure.

Therefore, J = ZL

By the property of a triangle,

Sum of all interior angles of a triangle is 180°.

m2J + m2K + m2L = 180°

mzJ + 72° + mzJ = 180° [Since, mzJ = mzL]

2mzJ = 180° - 72°

mzJ = 54°

Therefore, mZKJL or mzJ is 54°.

What is the measure of angle ABC?

Answers

Answer:

the answer is b.) 24

Step-by-step explanation:

you would set 3x + 12 and 6x equal because they have the same angle

[tex]3x + 12 = 6x[/tex]

then subtract 12 on both sides

[tex]3x = 6x - 12[/tex]

then subtract 6x from both sides

[tex] - 3x = - 12[/tex]

now just divide by 3 on both sides

[tex]x = 4[/tex]

then add it into the equation 3(4) + 12

The requried measure of angle ABC is 24°. Option B is correct.

What are the angle?

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
For two intersecting lines alternate angle is always equal.
3x + 12 = 6x
3x = 12
x = 4

Now,
6x = 6(4) = 24°

Thus, the requried measure of angle ABC is 24°. Option B is correct.

One month Mai rented 12 movies and 2 video games for a total of $53. The next month she rented 3 movies and 5 video games for a total of $38. Find the rental cost for each movie and each video game.

Answers

Answer:

Movie cost $3.5 and the video game cost $5.5

Step-by-step explanation:

Given data

Let the cost of movies be x

and the cost of video game be y

12x+2y= 53----------1

and

3x+5y= 38-----------2

solve 1 and 2

12x+2y= 53X 5

3x+5y= 38 X2

60x+10y= 265

- 6x+10y= 76

54x= 189

x= 189/54

x= $3.5

put x= 3.5 in 1

12(3.5)+2y= 53

42+2y= 53

2y= 53-42

2y= 11

y= 11/2

y= $5.5

Hence the movie cost $3.5 and the video game cost $5.5
