Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.
He's supposed to use a total of between 70 and 74 beads, so
70 ≤ b + g ≤ 74
The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so
1.4 ≤ g/b ≤ 1.6
For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions
b ≥ 0
g ≥ 0
(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)

(HELPP) twelve people can paint a barn in 15 days. how many days will it take for them to finish the work if each person's productivity is increased by 25%?
Answers
Answer:
11.25 days
Explanation:
15 / 12 = 1.25
1.25 x 0.75 = 0.9275
0.9375 x 12 = 11.25
15 times .25 and it will give you how many people you will have. Then you do 15/12 which gives you 1.25 then you multiply how many people you have and 1.25
3.75 x 1.25 = 4.68
4.68 is how many days it would take. Again I’m not sure I haven’t done this in a while
Does the equation have one solution, no solutions, or all solutions? 7x + 4 = 9(x-1)
Answers
Explanation:
First you remove the parenthesis
28=9x-9
Then you calculate
-9x = -9 - 28
Then you divide both sides
-9x = -37
Solution: 37/9
Alternative form:
4 1/9 or 4.1
Note: these are all the same solutions, they are just in different forms

Step-by-step explanation:
I'm not too sure which answer you're looking for but I'll try to answer all of them :).
First of all, we can consider them in percentage form first.
If the first sale price is marked down by 30%, it is now 70%.
For the second, the price is marked down by 20% first, so 80%.
And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.
As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price
Now we move on to the actual prices.
First one is 70% of the original price, 70% of $385 is $269.5.
Second one is 72% of original price, 72% of $385 is $277.2
Don't forget to round to the nearest dollar!

1000-100+10-1
Answers
Answer:
1000-100=900,900+10=910,910-1=909
Step-by-step explanation:
Hey there!
1,000 - 100 + 10 - 1
1,000 - 100 = 900
= 900 + 10 - 1
900 + 10 = 910
= 910 - 1
= 909
Thus that’s why 1,000 - 100 + 10 - 1 is most likely equal to 909
