Answer:
about 33.75 mg
Step-by-step explanation:
75% of 45 mg is ...
0.75 × 45 mg = 33.75 mg
About 33.75 mg of vitamin C are in one orange.
__
You might be asked to round this to 34 mg.
Equation of the table is given by
y - 210 = (280 - 210)/(4 - 3) (x - 3)
y - 210 = 70(x - 3)
y - 210 = 70x - 210
y = 70x
When x = 11, y = 70(11) = 770
Equation of the graph is given by
y = 110/2 x = 55x
When x = 11, y = 55(11) = 605
Therefore the value of y in the table is grater than the value of y in the graph by 770 - 605 = 165
1.

The ordered pairs (-2,3) and (5,1) make the inequality true.
2.

The simplified form of the expression is 3y-30.
Answer:
a) A = p(1 + r)^t
b) A = 500(1 + 0.07)^2=572.45
Step-by-step explanation:
t=2 in b)
-7n + 9 because the common difference is -7, so you have -7n, and then by plugging in the term numbers and the values, you find out that you need to add 9 to the -7n, so the answer is -7n + 9
