Step-by-step explanation:
This is the greater than symbol. Think of it like an alligator mouth that wants to eat the larger number. 3.2 is larger than -99.
H(x) = 3x + 12 + 5x + 10
h(x) = 8x + 22
in 4 hrs Colby can make: 3(4)+12 = 24$
in 4 hrs Dan can make: 5(4)+10 = 30$
together they make 22+30=52$ in 4hrs
if split equally that's 52/2=26$ a piece
yes, Colby doesn't make as much money so he will benefit from teaming up with Dan.
79. Set up an equation to solve this problem. Suppose she needs at least a score of x points. Her current total scores is 89+65+68+88=310. Her total score will be 310+2x (since final exams counts as two tests). The average score is total points divided by number of tests, and it has be bigger or equal to 78, so (310+2x)/6>=78. We solve it and get x=79. She has to score at least 79 on her final exam in order to jhave an overall average of 78.
