Answer:
3 x 4 = 12
4 x 5 = 20
5 x 2 = 10
Step-by-step explanation:
3 + 3 + 3 + 3 = 12
3 four times equals 12
This is the same for the others
4 + 4 + 4 + 4 + 4 = 20
Four 5 times equals 20
Answer:
[tex]3 \times 4 = 12 \\ 4 \times 5 = 20 \\ 5 \times 2 = 10[/tex]
Step-by-step explanation:
#1
Let the unknown number be x
[tex]x \times 4 = 12 \\ 4x = 12 \\ \frac{4x}{4} = \frac{12}{4} \\ x = 3 [/tex]
#2
Let the unknown number be y
[tex]y \times 5 = 20 \\ 5y = 20 \\ \frac{5y}{5} = \frac{20}{5} \\ y = 4[/tex]
#3
Let the unknown number be z
[tex]z \times 2 = 10 \\ 2z = 10 \\ \frac{2z}{2} = \frac{10}{2} \\ z = 2[/tex]
Hope this helps you.
