So because of PEMDAS you want to distribute the 2 to the parentheses so you'll get
6x-19=2x-2+11
Then you can just add like terms
6x-19=2x+9
Now you want to get all your variables on one side so you'd add 19 and subtract 2x
4x=28
Now you divide 28 by 4
x = 7

Answer:
1) 5/12
2) 4/3
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the tangent ratio is ...
Tan = Opposite/Adjacent
__
1) For angle Z, the ratio is ...
tan(Z) = XY/YZ = 10/25 = 5/12
__
2) For angle C, the ratio is ...
tan(C) = AB/BC = 20/15 = 4/3
740% = 7.4 = 7 4/10 reduces to 7 2/5
Answer:
y = 2x +13
Step-by-step explanation:
1. find the slope by using the formula y2-y1
--------
x2-x1
which is
23 - 19 4
------------ = --- = 2
5-3 2
2. finding the y intercept
so to find the y intercept you plug in the numbers to this formula
y-y1 = m (x-x1)
y - 19 = 2 (x -3)
y - 19 = 2x -6
+19 +19
y = 2x +13
Your answer for 15 is D or C. For 16 I’m estimating 125?
