B
Step-by-step explanation:
Answer:
-2t + 1400
Step-by-step explanation:
If t represents the number of hours Lamar worked as a tutor, the number of hours he worked as a waiter can be represented by 100 - t.
Create an equation to represent the situation:
12t + 14(100 - t) = total earned
Simplify:
12t + 1400 - 14t = total earned
-2t + 1400 = total earned
So, the expression for the amount he earned is -2t + 1400
3/4 = 0.75 or 75%. So you need to find 75% of 200... Simply multiply 0.75 or 3/4 by 200 and you will get your answer... (0.75)(200) = 150....
You could also realize with this problem that 3/4 of 200 is 150 because 50 goes into 200 4 times. 50 = 1/4, 100 = 2/4 = 1/2, 150 = 3/4 & 200 = 4/4 = 1.
Each side is x units long. There are 6 sides. So we add up all the sides to get the perimeter.
x+x+x + x+x+x
there are six copies of x being added
Simplifying that expression above leads to 6*x or simply 6x. Multiplication is a shortcut for repeated addition. Instead of saying 2+2+2+2, we can write 4*2
Answer: Choice C) 6x
