Answer 1

a.

15 + 2y = 21

2y = 21 - 15

2y = 6

y = 6/2

y = 3

b.

30 + 3y = 45

3y = 45 - 30

3y = 15

y = 15/3

y = 5

15 × 18 × 64⅔ = 15 × 18 × 194/3 = 5 × 18 × 194 = 90 × 194 = 17.460

Answer 2

Penjelasan dengan langkah-langkah:

1.) 15 × 18 × 64 2/3

• = 15 × 18 × 194/3
• = 15 × 6 × 194
• = 15 × 1.164
• = 17.460

2.)

A. 15 + 2y = 21

• 2y = 21 - 15
• 2y = 6
• y = 6/2
• y = 3

B. 30 + 3y = 45

• 3y = 45 - 30
• 3y = 15
• y = 15/3
• y = 5
