Answer:
2x - 7 = -12
Step-by-step explanation:
[twice the number of x] [decreased] [7] [is the same as] [negative 12]
Step-by-step explanation:
X+3/7= 5/4
X= 5/4-3/7. Take LCM of 4, 7 will be 28
X= 35/28-12/28
X= 23/28 Answer

Answer:
15-3(3a+b)+5-6b
15 - 9a - 3b + 5 - 6b
15 - 9a - 9b + 5
20 - 9a - 9b
Step-by-step explanation:
15-3(3a+b)+5-6b
Multiple everything inside of the parenthesis by -3.
15 - 9a - 3b + 5 - 6b
Get the variables together by doing -3b-6b
15 - 9a - 9b + 5
Add 5 to 15.
20 - 9a - 9b
Final answer: 20 - 9a - 9b
Answer:
54.2
Step-by-step explanation:
we want to find m∠T
Recall the three main trig functions
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
we are given the side length opposite of ∠T ( SU ) and the adjacent (TU)
when dealing with the opposite and adjacent we use tan
tan = opposite / adjacent
opposite (SU) = 18 and adjacent (TU) = 13 ( let ∠T = x )
So tan(x) = 18/13
* take the inverse tan of both sides *
arctan(tan(x)) = x
acrtan (18/13) = 54.2
we're left with x = 54.2 meaning that ∠T = 54.2
