B) C=0.23m+34.99
because you get you base price definitely and extra minute price can be removed if you don't use more than 100
Answer:
Step-by-step explanation:
It's - 12 tonight. It would be amazing if the temperature difference was 25 degrees.
T_noon = - 12 + 25 = 13 degrees.
B. Line K has a slope of -3
Distance = final height - depthOFdolphin
Distance = 2.4 - (-5.5)
Distance = 2.4 + 5.5
Distance = 7.9 meters
A math expression is anything where you take one or more numbers and add them, subtract them, multiply, divide, etc etc
For example, 2+3 is a math expression
To make it an algebraic expression, we replace one of the numbers with a variable. Often this is the letter x. So let's say we replace the 2 with x. That would have the expression turn into x+3. What we're saying is "some number plus 3"
Normally 2+3 = 5 which is a true equation. Replace the 2 with x and we have x+3 = 5. So we're saying "some number plus 3 is 5". You can guess and check to find that the "some number" has to be 2
--------------------------------------
In summary, the expression example was x+3 and the equation was x+3 = 5
Note: an equation is simply two expressions set equal to each other.
