You'd need to start by finding what 40% of 280 is. To do this, you turn 40% into a decimal which is .40 . Multiply .40 x 280 which is 112. Then subtract that answer from 280 which is 168 baseball cards. Hope this helped :)
Answer:
Your expression doesn’t seem writable
Step-by-step explanation:
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context
The equation of a line is y = mx + b. The variable m is the slope, so m = 2/3, giving you the equation y = (2/3)x + b. To find b (the y-intercept), plug in the given x and y values. So, it'll look like this: (-3) = (2/3)(7) + b. Finally, solve algebraically for b:
Multiply 2/3 by 7.
-3 = 14/3 + b
Subtract 14/3 from both sides.
-23/3 = b
The final equation is y = (2/3)x - 23/3.
You have to multiply bro & rewrite your question
