100% = 60

55% = 33

80% = 48

35% = 21

Step-by-step explanation:

9 ÷ 15% = 60

60 x 100% = 60

60 x 55% = 33

60 x 80% = 48

Answer:  Create equations. Top length=Bottom length

Left side = right side.

Combine like terms and rewrite the equations.  

Use the new equations to create a system of equations to solve for x and y.

Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.

You should end up with top and bottom lengths of 10. The sides are 9.

Step-by-step explanation:

3x-5 = 18 -2y . Rewrite as 3x + 2y = 23

x+4 = 21 -3y    Rewrite as  x + 3y = 17

The system of equations is

3x + 2y = 23   and  x + 3y = 17 . To solve by substitution, multiply the second equation by -3   It becomes  -3x-9y= -51  Add the equations so the x terms cancel. Solve for y

3x + 2y = 23

-3x - 9y = -51

0  -7y  = - 28  Divide both sides by -7.   y = 4

Substitute 4 for y,  solve for x

x + 3(4) = 17

x + 12 = 17 . Subtract 12 from both sides   x = 5

Substitute the values of x and y in the expressions

Top: 3x-5    is 3(5) -5  becomes 10

Bottom: 18 -2y  is  18 - 2(4) becomes 10

Left:  x +4   is (5) + 4  becomes 9

Right:  21 - 3y  is  12 -3(4)  becomes 9

Scalene Triangle

Step-by-step explanation:

We are told that he drew a triangle MNR. Now, the sides are given as;

MN = 2 cm

NR = 4 cm

RM = 3 cm

This means that the 3 sides are not equal. And a triangle with it's 3 sides being unequal is called a scale me triangle.

Answer:

16 turtles

20 frogs

32 fish

Step-by-step explanation:

let 't' = # turtles

let '4 + t' = # frogs

let '2t' = # fish

t + 4 + t + 2t = 68

4t + 4 = 68

4t = 64

t = 16 turtles

4 + 16 = 20 frogs

2(16) = 32 fish

Answer:

The slope is 4/3x

Step-by-step explanation:

We can easily find the slope, by looking at the difference between each number on the table. We can see that the x values are rising in 3's, and the y values are rising in 4's. From that we can find the slope, 4/3x, since the slope rises up positive 4, and runs positive 3.

EDIT: forgot the x after the slope

I don't have c but I do have a and b

Step-by-step explanation:

Part A)

Angle 3 is 103° because 77° + ∠3= 180° and  ∠3 = 180° - 77° = 103°

Part B)

Angle 4 is 77° because ∠3 + ∠4 = 180° and  ∠4 = 180° - 103° = 77°

Answer:

Just remember that straight lines are always 180° (a + b = f)

Step-by-step explanation:

Assuming the triangle is equiangular and equilateral, a b and c are the same, so they are interchangeable.

f + c = 180 becuase it is a straight line. you can switch out c with a because they are the same. So:

f+a=180

(switch out with b)

f+b=180

GUESSING this is equiangular, a and b must add up to 120 because they are are both 60.

If a line is 180 degrees and c is 60 (same as a and b) then f will be 180-60 which is 120. 120 is the same as the sum of a and b, so you could write:

a + b = f

The relationship between angles f, b, and a could be as a + b = f.

Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.

WE can see that the triangle is equiangular and equilateral, Also angles a b and c are the same, so they are interchangeable.

WE know that the base makes the straight line

f + c = 180

So: f + a = 180

Similarly

f + b = 180

Assuming this is equiangular, a and b must be add to 120, they are both 60 degrees

If we consider the line is 180 degrees and c is 60 then f will be 180-60 which is 120.

120 degree is the same as the sum of a and b, so we could write:

a + b = f

Hence, the relationship between angles f, b, and a could be as a + b = f.

Answer: 18 pies, 22 cakes

Step-by-step explanation:

Let the number of pies sold be represented by p.

Let the number of cakes be represented by c.

The information in the question can then be represented in an equation as:

p + c = 40 ........ i

10p + 8c = 356 ....... ii

Multiply equation i by 10

Multiply equation ii by 1

10p + 10c = 400 ....... iii

10p + 8c = 356 ....... iv

Subtract iv from iii

2c = 44

c = 44/2

c = 22

22 cakes were sold

Since 40 items were sold, the number of pies sold will be:

= 40 - 22

= 18 pies
