Answer: 36
Step-by-step explanation:
From the question, we are informed that for every 4 silver cars that are sold, 6 red cards are also sold.
When there are 90 cars sold in a month, the number of silver cars that were sold would be:
= [4 / (4 + 6)] × 90
= 4/10 × 90
= 4 × 9
= 36 silver cars
819 as a decimal is
<em> 819.00000</em>
with as many zeros as you want after the decimal point.
If you do anything else to it, then it's a different number,
and it's not 819 anymore.
≤ is called a less than or equal to sign. It is a solid line since it has "or equal to". You can check and graph by substituting in (0, 0) into x ≤ 3 to see if the statement is true or false. 0 ≤ 3 is true, so you can shade in the left side of the solid line.
The answer is 64 which goes into evenly 8 times 8, 49 7 times 7, 4, 2 times 2, 144 12 times 12
