Answer:
Step-by-step explanation:
3(2x - 8) + 4x = -2(12 - 7x) - 4x
6x - 24 + 4x = - 24 + 14x - 4x
10x + 24 = 24 + 10 x
Answer:
12.0
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the trig function relating the adjacent side of an angle in a right triangle to the hypotenuse:
Cos = Adjacent/Hypotenuse
Filling in the given values, we have ...
cos(24°) = 11/x
Multiplying this equation by x/cos(24°), we get ...
x = 11/cos(24°) ≈ 12.0

Step-by-step explanation:
A. Let x represent the original test scores.
(1) The teacher will give a 10-point bonus, then the score will be x + 10. Hence,
(2) The teacher will increase everyone's grade by 9% of their score, then the score will be x + 0.09x = 1.09x. Hence,
B. If and then
Meaning: the teacher increased by 9% the score and then increased the result by 10 points.
C. If and then
Meaning: the teacher increased by 10 points the score and then increased the result by 9%.
D. because
