1. Terms 2 and 3 are called means.

2.

36 : 18 = x : 1

(36)(1) = (x)(18)

36 = 18x

36/18 = 18x/18

2 = x

3.

N/8 = 3/4

(N)(4) = (3)(8)

4N = 24

4N/4 = 24/4

N = 6

4.

8 : 4 = 192

8x + 4x = 192

12x = 192

12x/12 = 192/12

x = 16

8x = 8(16) = 128

5.

5/12 = 35/N

(5)(N) = (35)(12)

5N = 420

5N/5 = 420/5

N = 84

6.

96 : 6 = x : 20

(96)(20) = (x)(6)

1,920 = 6x

1,920/6 = 6x/6

320 = x

7. 1/4 = 25%

8. 2/5 = 40%

9. 6.45 = 645%

10.

P = br

P = (80)(20%)

P = (80)(0.2)

P = 16

11.

P = br

P = (50)(20%)

P = (50)(0.2)

P = 10

12.

Discount = P500 x 25%

Discount = P500 x 0.25

Discount = P125

Selling Price = P500 - P125 = P375

13.

b = p/r

b = 16/20%

b = 16/0.2

b = 80

14.

r = p/b

r = 60/240

r = 0.25

r = 25%

64

Step-by-step explanation:

log x 8 = 1/2

converting to exponential form:

x^(1/2) = 8

x = 64

We have x =5y + 3 so we plug in this value in the first equation

3x + 5y =-6

3(5y + 3) + 5y =-6

20y = -15

y = -15/20 = -3/4

So:

X= 5y + 3

X= 5(-3/4) +3 = 15/4 + 3 = 3/4
