The answer is B as it is the only one that matches the 2 inequalities.
2(4z - 6 - 6) = 170 - 46
2(4z - 12) = 124 |use distributive property: a(b - c) = ab - ac
8z - 24 = 124 |add 24 to both sides
8z = 148 |divide both sides by 8
z = 18.5
Answer: 9/10 times
Step-by-step explanation:
Hi, to answer this question we simply have to divide 18/25 by 4/5
Mathematically speaking:
18/25 ÷ 4/5 = (18 x 5) / (25 x 4) = 90/100 = 9/10
In conclusion, the answer is 9/10 times.
Feel free to ask for more if needed or if you did not understand something.
1800 ft² = 3 pounds
[divide by 3 through]
1800 ÷ 3 = 3 ÷ 3
600ft² = 1 pound
[8400 ÷ 600 = 14; so multiply by 14 through]
600 x 14 = 1 x 14
8400ft² = 14 pounds
we need 14 pounds to cover 8400 square feet.
[Find number of 4 pounds bags needed]
14 ÷ 4 = 3.5
So we need to use 4 bags of 14 pounds of lawn seeds.
1 pound (lb) is in 16 ounces (oz).
