Answer:
7
Step-by-step explanation:
We are to solve 4.2÷0.6 using base 10 blocks
4.2 = 42/10
0.6 = 6/10
4.2÷0.6
= 42/10 ÷ 6/10
= 42/10 * 10/6
= 42/6
= 7
Hence the required expression using base 10 block is 7
Answer:
t = 0
Step-by-step explanation:
You should know that
p ⇒ q ≡ ¬p ∨ q
so that
p ⇒ (q ∧ r) ≡ ¬p ∨ (q ∧ r)
Then making the truth table is simple:
Answer:
equation 1: x-5=-8 <=> x=-3
equation 2: x-3=-6 <=> x=-3
equation 3: x.3=-9 <=> x=-3
equation 4: -9 : x=3 <=> x=-3
=> Four equations that have –3 as the solution: x=-3
