2b + 21 < 22
b is the unknown number so multiply it by 2 to get 2b then add 21, bring the less than sign and write the 22 after the less than sign
1.
g > 6.4
<h3>Answer: A. 7 > 6.4</h3>
2.
y + 2 > 8 <em>subtract 2 from both sides</em>
y > 6
<h3>Answer: D. 7 > 6</h3>
3.
6 > z(10 - z)
A. z = 0 → 6 > 0(10 - 0) → 6 > 0 CORRECT
B. z = 1 → 6 > 1(10 - 1) → 6 > 1(9) → 6 > 9 FALSE
C. z = 2 → 6 > 2(10 - 2) → 6 > 2(8) → 6 > 16 FALSE
D. z = 3 → 6 > 3(10 - 3) → 6 > 3(7) → 6 > 21 FALSE
<h3>Answer: A. 0</h3>
4.
The list of factors of 24:
1, 24, 2, 12, 3, 8, 4, 6
<h3>Answer: D. {1, 2, 3, 4, 6, 8, 12, 24}</h3>
The computation shows that the amount will be 44.70 Dollars.
<h3>How to illustrate the information?</h3>
The options are missing: Here are the missing options:
A. 44.70 US dollars
B. 73.06 US dollars
C. 136.87 US dollars
D. 140.41 US dollars
For solving this question first we will convert the USD to euros.
The conversion rate we have is:
1 euro = 1.3687 USD
250/1.3687 = 182.655 euros
Now we will subtract it from what he has spent:
= 182.655 - 150
= 32.655 euros
Now we will again convert it back to USD. This will be:
32.655 euros * 1.3687 = 44,695 us dollars
Therefore, the answer is 44.70.
