Question

10 x n = 360 n = _____ (3 x 4) x 5 = k x (5 x 4) k = ____

Answer 1

Answer:

$n = 36 \\ k = 3$

Step-by-step explanation:

#1

$10 \times n = 360 \\ 10n = 360 \\ \frac{10n}{10} = \frac{360}{10} \\ n = 36$

#2

$(3 \times 4) \times 5 = k \times (5 \times 4) \\ 12 \times 5 = k \times 20 \\ 60 = 20k \\ \frac{60}{20} = \frac{20k}{20} \\ 3 = k$

Hope this helps you.

Answer 2

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
