Answer:
y = 2
Step-by-step explanation:
y=2 every time you add 3 to x your adding 2 to the y
-3 + 3 = 0 and 3 + 2 = 5
0 + 3 = 3 and 5 + 2 = 7
To get this, you divide the smaller number by the larger one and get 0.5882... 500 is about 59% of 850, so to find the percent lost, you subtract that from 100 to get 41% decrease
Answer:
A'(5.5, -4.2), B'(7.5, -9.2), C'(3.5, -3.2)
Step-by-step explanation:
I really do hope I understood you correctly. I figured that the rule would have to be added to each point. If those are wrong, try subtracting the rule.
Again, I'm not trying to take your points and leave you with a wrong answer. I really did give it my best.
Answer:
61.84%
Step-by-step explanation:
Let the cost of the box be x. Since the price of the box and the pen is Rs 80, the pen's price can be represented as 80 - x. The box is sold at a ten percent profit, and an added ten percent is equal to 1.1. Therefore, the price the box sells at is 1.1(x). A 20% loss is the same a keeping 80% or multiplying by 0.8. This means the pen sold at 0.8(80 - x). Now, we are given the box went for Rs 28 more than the pen, so we can create an equation:
1.1x = 0.8(80 - x) + 28
We can simplify and solve:
1.1x = 64 - 0.8x + 28
1.9x = 92
x = 92/1.9
x = 920/19
The cost of the box after the increase would be 1.1(920/19) and the pen would be 0.8(80 - 920/19).
The sum of these two can be written as a percent x of 80.
80x = 0.8(80 - 920/19) + 1.1(920/19)
80x = 64 - 0.8(920/19) + 1.1(920/9)
80x = 64 - 0.3(920/19)
80x = 64 - 276/19
80x = 940/19
x = 940/1520
x = 0.6184
This is 61.84%
Answer:
x=3.5
Step-by-step explanation:
1. Multiply
18x-12=5x+30
2. Move the x's to one side
12x= 42
3. Isolate the variable by dividing
x=3.5
