Answer:
9x
Step-by-step explanation:
Let
x -----> a number
we know that
The algebraic expression of the phrase "the product of nine and a number"
is equal to multiply the number 9 by the number
so
(9)(x)=9x
Step-by-step explanation:
0x<3
x>3/0
x>∞
x is undefined.
Answer:
a).
= (67×10)÷2
= 670 ÷ 2
= 335
Explanation:
a).
= (67×10)÷2
= 670 ÷ 2
= 335
So, 5×67 = (67×10)÷2
=> 335 = 335
b).
= (67x2)+(67×2)
= 134 × 134
= 268
So, 5×67 ≠ (67x2)+(67×2)
=> 268 ≠ 335
c).
= (6 ×7)×5
= 42 × 5
= 210
So, 5×67 ≠ (6×7)×5
=> 210 ≠ 335
d).
= (5×6)+(5×7)
= 30 + 35
= 65
So, 5×67 ≠ (5×6)+(5×7)
=> 65 ≠ 335
