1 answer:
Ahat [919]2 years ago
7 0

Step-by-step explanation:

what answer is needed ? the result of the calculation ?

I assume this is the case.

remember that regarding the sequence of operations brackets are first, then exponents, then "dot" operations (× and ÷), and only at the very least come the "dash" operations (+ and -).

and that a combination of - + or + - results in -.

14 + 16 ÷ 2³ - (12 + 3²) ÷ 7 + 2 × (-5) =

14 + 16 ÷ 2³ - (12 + 9) ÷ 7 - 2 × 5 =

14 + 16 ÷ 2³ - 21 ÷ 7 - 2 × 5 =

14 + 16 ÷ 8 - 21 ÷ 7 - 2 × 5 =

14 + 2 - 3 - 10 = 3

What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}?
Sophie [7]
Hi there! The answer is B.

5r \leqslant 6r - 8
Subtract 6r from both sides.

- r \leqslant  - 8
Divide both sides of the inequality by -1. Remember that dividing by a negative makes the sign flip.

r \geqslant 8
Therefore, the solution must be bigger than or equal to 8. From the given solution set, the answer is B. {8, 9, 10}

~ Hope this helps you!
