Answer:

Value of given expression is 6434.5532 and number of significant figures is 8.

Step-by-step explanation:

The given expression is

(1712 - 1615) \times (8.66 \times 7.66)

We need to find the value of given expression.

On simplifying the parentheses we get

(97) \times (66.3356)

On multiplication we get

6434.5532

Therefore, the value of given expression is 6434.5532 and number of significant figures is 8.

Which of the following ordered pairs represents the solution to the system of equations below?
expeople1 [14]
<span>-3x + 2y = 2  eq (1)

  7x - 3y = 7    eq (2)

Mutiply eq (1) by 3 and eq (2) by 2:

-9x + 6y = 6

14x - 6y = 14

Add th two new equations:

-9x + 14x = 6 + 14

=> 5x = 20

=> x = 20/5

=> x = 4

Now from eq (1)

-3(4) + 2y = 2

=> 2y = 2 + 12

=> 2y = 14

=> y = 14 / 2

=> y = 7

So the ordered pair is (4,7)

Answer: option B. (4,7)
