Mathematics
1 answer:
Oliga [24]2 years ago
5 0

Answer:

Step-by-step explanation:

5.

point = (x, y)

A = (1\frac{1}{2}, 12)

B = (2\frac{1}{2}, 20)

C = (3, 24)

D = (3\frac{1}{2}, 28)

y/x ratios

\frac{12}{1\frac{1}{2} }

\frac{20}{2\frac{1}{2} }

24/3

\frac{28}{3\frac{1}{2} }

6.

(1 2/3, 3 1/3) = 3 1/3 ÷ 1 2/3 = 2

(1 1/4, 2 1/2) = 2 1/2 ÷ 1 1/4 = 2

(3, 7) = 7 ÷ 3 = 2 1/3

(4 1/2, 9) = 9 ÷ 4 1/2 = 2

The ratio 7/3 (x = 3 and y = 7) is not proportionally related to the others.

The other ratios are equal to each other and are therefore in proportion.

7. yes

The difference of two positive numbers is 69. The quotient obtained on dividing one by the other is 4. Find the number.​
valentinak56 [21]

Answer:

x=92 y=23

Step-by-step explanation:

Let them be x and y respectively

so given

x-y=69

and

x/y=4  x=4y

so we can write

x-y=69

as

4y-y=69  3y=69 y= 69/3 = 23

now y is 23

so putting in any equation will give the value of x

so

x-23=69 x=92
