which of the following equations are true? a)1+1=1x1 b)7x1=0+7 c)3+1=3x0 d)6x1x0=6+1+0

Answer 1

Let's evaluate each of the equations one by one:

a) \(1 + 1 = 1 \times 1\)

• Left side: \(1 + 1 = 2\)
• Right side: \(1 \times 1 = 1\)
• Not true (2 ≠ 1)

b) \(7 \times 1 = 0 + 7\)

• Left side: \(7 \times 1 = 7\)
• Right side: \(0 + 7 = 7\)
• True (7 = 7)

c) \(3 + 1 = 3 \times 0\)

• Left side: \(3 + 1 = 4\)
• Right side: \(3 \times 0 = 0\)
• Not true (4 ≠ 0)

d) \(6 \times 1 \times 0 = 6 + 1 + 0\)

• Left side: \(6 \times 1 \times 0 = 0\)
• Right side: \(6 + 1 + 0 = 7\)
• Not true (0 ≠ 7)

Therefore, the only true equation is b) \(7 \times 1 = 0 + 7\).
