Answer:
7x + 2
Step-by-step explanation:
5 - 4 + 7x + 1
= 1 + 7x + 1
= 7x + 2
hope this helped u bud :)
All students in each grade
audience: <u>students</u> - counts for both boys and girls.
option (B) for teachers is irrevelant.
option (C) doesn't include girls.
option (D) doesn't include the entire school
Hence, option A is correct.
1- (9/2)
2- (-5/2)
3- (-4/3)
4-if it’s -8/3 divided by -1/2 then it’s (16/3)
You just have to multiply them by the second terms reciprocal
Hope it helps
Answer:
Step-by-step explanation:
7) - 1
tan <BAD = BD / AD
BC = √(64 + 36)
BC = √100
BC = 10
now you can solve BD
BD/6 = 6/10
BD = 6*6 / 10
BD = 36/10
BD = 3.6
AD = √36 - 12.96
AD = √23.04
AD = 4.8
tan <BAD = BD / AD
tan <BAD = 3.6 / 4.8
tan <BAD = 0.75
7) - 2
cos <DAC + cos <DAB
as you know cos = Adj / Hypo
cos <DAC = AD/AC
cos <DAC = 4.8 / 8
cos <DAC = 0.6
cos <DAB = AD / AB
cos <DAB = 4.8/6
cos <DAB = 0.8
so
cos <DAC + cos <DAB = 0.6 + 0.8
cos <DAC + cos <DAB = 1.4
