2400 divided by 44% which is 1056.
(sneaky way to put history in math, btw...)
Based on the given information, let x represent the grade for the fifth quiz.
(79+88+95+71+x)/5=85
(333+x)/5=85
333+x=425
x=92
Jackson would have to earn a 92 on his fifth quiz to earn an average of 85.
Answer:
338 is the difference
Step-by-step explanation:
505-167=338
(x + 5)^2 + (x/2 + 6)^2 = (30)^2
Take it from here.
We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90°
in this problem
(x+21)+<span>(2x+21)=90-------> 3x+42=90-------> 3x=48-----> x=16</span>°
