The first three you should check off because the man lost less so the last few questions would be wrong
In this case you go to the thousandths so,-.261, -0.262 ,-0.263,-0.264,and so on.you could even go to the millionths,for example -0.2611
6 - a =
(9a - 18)
First, simplify
to
/ Your problem should look like:
Second, multiply both sides by 3. / Your problem should look like:
Third, expand. / Your problem should look like:
Fourth, add 3a to both sides. / Your problem should look like:
Fifth, simplify 9a - 18 + 3a to 12a - 18. / Your problem should look like:
Sixth, add 18 to both sides. / Your problem should look like:
Seventh, add 18 + 18 to get 36. / Your problem should look like:
Eighth, divide both sides by 12. / Your problem should look like:
Ninth, since 3 goes into 12 to get 36, simplify
to 3. / Your problem should look like:
Tenth, switch sides. / Your problem should look like:
Answer:
a = 3 (one solution)
Answer:
72
Step-by-step explanation:
1. Proportion:
8/15=x/135
2. Answer is 72
Given:
The tens digit of a two digit number is 5 greater the units digit.
If you subtract double the reversed number from it, the result is a fourth of the original number.
To find:
The original number.
Solution:
Let n be the two digit number and x be the unit digit. Then tens digit is (x+5) and the original number is:
Reversed number is:
If you subtract double the reversed number from it, the result is a fourth of the original number.
Multiply both sides by 4.
Divide both sides by 55.
The unit digit is 2. So, the tens digit is .
Therefore, the original number is 72.
