what questions is that and give it as in details mayb i can help u with it
Answer:
y = 4
Step-by-step explanation:
2[2y-1]+5=19 (by PEDMAS, distribute parentheses first)
(2)(2y) - (2)(1) + 5 = 19
4y - 2 + 5 = 19
4y +3 = 19 (subtract 3 from both sides)
4y = 19 - 3
4y = 16 (divide both sides by 4)
y = 16/4
y = 4
Answer: cos y°=t divided by 8
Step-by-step explanation:
Given the following :
tan y° = s / t
sin y° = s / 8
Using Pythagoras rule ;
sin y° = opposite / hypotenus = s / 8
tan y° = opposite / Adjacent = s / t
Therefore,
cos y° = Adjacent / Hypotenus
Cos y° = t / 8

We have a dilemma here, there is a variable and constant numbers in this equation. No fear, this is when like terms comes into play, where you can only combine two numbers that have the same ending, whether it be variables, exponents, e.t.c.
Distribute :
4 + 16 - 12(1 + 2x)
4 + 16 - (12(1) + 12(2x))
4 + 16 - 12 + 24x
Use PEMDAS (Add left to right) :
4 + 16 - 12 + 24x
20 - 12 + 24x
8 + 24x
24x + 8
