Answer:
<em>5x + 1</em>
Step-by-step explanation:
f(x) = 3x + 2
g(x) = - 2x + 1
<em>f(x) - g(x)</em> = 3x + 2 - ( - 2x + 1 ) = 3x + 2 + 2x - 1 = <em>5x + 1</em>
5.5 or either they would all get 4
0.95
Because 1 is the total, so 1 - 0.05 = 0.95
Let x be the number of seventh grade students.
The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.
The 16 2/23% of those students also have science class in the morning means:
16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning
30 students have math in the morning but not science in the morning
83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180
There are 180 seventh graders.
