Answer:

Step-50*t + 30*m = 1500, (1) (pounds)

4*t + 3*m = 138. (2) (cubic feet)

From (2), express 3m = 138 - 4t, and substitute it into (1). You will get

50t + 10*(138-4t) = 1500, or

10t = 1500 - 1380 ---> 10t = 1120 ---> t = 112 TVs.

From this point, find the number of microwaves on your own.

Multiply: 2.7 × (–3) × (–1.2). A. –9.72 B. –10.8 C. 10.8 D. 9.72

Vikentia [17]

Answer: $\text{ D) } 9.72$

Step-by-step explanation:

Here the give expression is,

$2.7 \times(-3)\times (-1.2)$

We can write,

$2.7 \times(-3)\times (-1.2) = 2.7 \times 3.6$ ( because $-a\times -b = ab$ )

$2.7 \times(-3)\times (-1.2) = 9.72$

⇒ Option D is correct.
