Step-by-step explanation:
<h3>Question 9</h3>
<u>The smaller number is x, the greater number is x + 4, their sum is 52:</u>
Correct choice is B
<h3>Question 10</h3>
<u>$8 and 9n should sum at least $80:</u>
- 8 + 9n ≥ 80 ⇒ 9n ≥ 72 ⇒ n ≥ 8
Correct choice is A
<h3>Question 11</h3>
<u>$43 and 3n should sum at least $70:</u>
- 43 + 3n ≥ 70 ⇒ 3n ≥ 27 ⇒ n ≥ 9
Correct choice is A
<h3>Question 12</h3>
<u>P books cost $10.01p and $9.96 for shipping, the total should be no more than $50:</u>
- 9.96 + 10.01p ≤ 50 ⇒ 10.01p ≤ 40.04 ⇒ p ≤ 4
Correct choice is D

Mutliplying decimals with numbers
Lets do the following multiplication
25
x419
9x25 = 2 2 5
1 x 25 = 2 5 0
4 X25 = 100 0 0 ...... add colums from top to bottom
= 1 0 4 7 5
for a decimal , just add a dot . or comma after 104 , this will be 104.75
so 25 x 4.19 = 104.75
