Answer:
multiply by -3, multiply by -2, multiply by -1, ...
Step-by-step explanation:
Answer:y = 2/3
Step-by-step explanation:
2x + y = 10
x - y = 4
-----------------add
3x = 14
x = 14/3
x - y = 4
14/3 - y = 4
-y = 4 - 14/3
-y = 12/3 - 14/3
-y = -2/3
y = 2/3 <==
Answer:
67.33.
Step-by-step explanation:
To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
You should leave $10.52 for the waiter if you want to leave him exactly 20%.
To figure the tax, you need to find 8% of $52.60.
0.08×52.6=4.208
Next, add them up:
52.6+10.52+4.208=67.328
The total bill, including tax and tip, will be $67.33.
Integers are whole numbers, which van be positive and negative. Positive integers are the hole numbers greater than zero, while negative are the whole numbers smaller than zero.
The thermometer for example uses positive integers (temperature presented in degrees greater than 0 degrees Celsius: 25 <span>°C</span>, and negative integers (temperature below zero , example -15 °C) .
You do (3)*(3)*(3)= 27
Then you do (4)*(4)*(4)= 64
Now you add them 27*64= 1728
I know this is correct because I am doing the same thing in my math class.
Hope this helps. :)
