Can you take a better pic? and nukber 1 is supplemntary so it is half
4.35/48 = 0.090625
Answer: 0.090625
f(a + 2)= 3a +
substitute x = a + 2 into f(x)
f(a + 2) = 3(a + 2) +
= 3a + 6 + = 3a +
68% +75 % +79 % +x ÷4≥ 80%
.68 + .75 + .79+x ÷4* 4 ≥ . 80*4
.68 + .75 + .79+x ≥ 3.2
2.22 + x ≥ 3.2
2.22 -2.22+x ≥ 3.2 -2.22
x ≥ 0.98
She has to get at least 98% to get an B.
It would be D 54/60
thanks
