Answer:

16/20

Step-by-step explanation:

We can write this as a proportion

4          x

----- = ----------

5          y

Using cross products

4y = 5x

We know that x+y = 36

We have 2 equations and 2 unknowns.

4y = 5x

x+y =36

Divide by first equation by 4

y = 5/4 x

substitute this into the 2nd equation

x + 5/4x = 36

Getting a common denominator

4/4x + 5/4 x = 36

Combining like terms

9/4 x =36

Multiply each side by 4/9 to isolate x

4/9 * 9/4x = 4/9*36

x = 16

Now we need to find y

y = 5/4x

y = 5/4 (16)

y= 20

The fraction is x/y

16/20

Isabel wrote this mystery problem. The quotient is multiple of 6. The dividend is multiple of 9. The divisor is a factor of 12.
Marina86 [1]

Answer:

Consider the expression q=\frac{a}{b}. q is called the quotient, a is is the dividend and b is the divisor.

Since q is a multiple of 6, then q has the form q=6k for some integer k.

Since a is a multiple of 9, then a has the form a=9s for some integer s.

Since b is a factor of 12, then if 12 can be expressed of the form 12=c*b, for c an integer. Then b has the form b=\frac{12}{m}

Replacing the preview expression in the initial expression we obtain:

6k=\frac{9s}{\frac{12}{m}}=\frac{9sm}{12}\\6*12k=9sm\\72k=9sm\\72k-9sm=0

Then 72k-9sm=0,\; for \; k,s,m\in \mathbb{Z} is a equation to Isabel's problem.

Perpendicular from C on AB is the height of the parallelogram = 4.5cm

Area of a parallelogram : base * height

Area of a parallelogram = length base * height

Area of a parallelogram = 7.2 cm * 4.5cm
