Sagot :
Step-by-step explanation:
10 × n = 360
n = 360 ÷ 10
n = 36
So, n = 36
(3 × 4) × 5 = k × (5 × 4)
12 × 5 = k × 20
60 = k × 20
k = 60 ÷ 20
k = 3
So, k = 3
Answer:
[tex]n = 36 \\ k = 3[/tex]
Step-by-step explanation:
#1
[tex]10 \times n = 360 \\ 10n = 360 \\ \frac{10n}{10} = \frac{360}{10} \\ n = 36[/tex]
#2
[tex](3 \times 4) \times 5 = k \times (5 \times 4) \\ 12 \times 5 = k \times 20 \\ 60 = 20k \\ \frac{60}{20} = \frac{20k}{20} \\ 3 = k[/tex]
