Answer:
40 1/2 days
Step-by-step explanation:
Quantity of biscuits the Jones eats daily = 2/3 of a packet
Total packets of biscuits = 27 packets
How long will 27 packets last the family?
= Total packets of biscuits / daily intake of biscuits of the Jones
= 27 ÷ 2/3
= 27 × 3/2
= 81 / 2
= 40 1/2 days
Answer:
Step-by-step explanation:
7x + 8y + 5z
I put the equations in parentheses, assuming that I would be adding both of the equations together. Then, I removed them and combined the like terms. I used two calculators to check my answer, and this should be correct.
1.7a + 0.3a = 0.8;
(1.7 + 0.3)a = 0.8;
2 x a = 0.8;
a = 0.8 ÷2;
a = 0.4;
Answer:
x>3
Step-by-step explanation:
Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?
You mean '39 is what percent of 12.5 ?'
So, the answer is
39/12.5 × 100
= 3.12 × 100
= 312%
So, 39 is 312% of 12.5.
(The percentage is greater because 39 is greater than 12.5)
