The solution to the amount of light bulbs Julia needs to sell to meet her quota is represented by the shaded area in graph X.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the incandescent light bulbs and y represent the fluorescent light bulbs. Therefore:
x + y > 100 (1)
Also:
2x + 5y ≥ 350 (2)
The solution to the amount of light bulbs Julia needs to sell to meet her quota is represented by the shaded area in graph X.

Answer
I would say Chimpanzees
Step-by-step
Not only are they our closest ancestors, they are one of the few animals that actually use tools to get food. They're pretty interesting creatures
Q1
Divide each distance by its time to find the speed for each driver.
T: 380 km / 4 hr = 95 km/h
M: 530 km / 5 hr = 106 km/h
Martine's average speed was greater.
Q2
Bronze to aluminum is 25:2
The alloy is bronze plus aluminum, so by adding 25 + 2 you get 27.
Bronze to total is 25:27
25 is 27 as x is to 55
25/27 = x/55
27x = 25 * 55
x = 50.926
Answer: 50.926 kg of bronze
Q3
Manipulative toys to art toys is 30:40
Total toys = 30 + 40 = 70
manipulative toys are 30 out of 70
30/70 * 100 = 42.9%
You need to group the like terms (the terms with the same or no variable) together so it is:
5y-6y-y +6
Then you combine the like term and it becomes
5y-7y +6
-2y+6
which can also be written as 6-2y
Hope this helps :)
