They do not mean the same thing:
4 in 4000 stands for 4 thousands
4 in 400 stands for 4 hundreds.
You can see, that first '4' means 4 000, while the second one means 400, so the first one is 10 times greater.
Answer:
C
Step-by-step explanation:
∠ TUL + ∠ LUV = ∠ TUV , substitute values
x + 16 + 11x = 172 , that is
12x + 16 = 172 ( subtract 16 from both sides )
12x = 156 ( divide both sides by 12 )
x = 13 → C
Answer:
-3.8 - (7.2-10 3/8)
-3.8+(-7.2+10 3/8) this is the error, it's positive 10 3/8, not negative, then you should solve what's in the parentheses first
I simplified 10 3/8 into 83/8 and then 10.375
-3.8+(-7.2 + 10.375)
-3.8+ 3.175 = -0.625
The system of equations is
y = 3x - 4
y =(2/3)x + 1
The solution satisfies
3x - 4 = (2/3)x + 1
Answer:
From the graph, obtain
x lies between 2 and 3.
y lies between 2 and 3.
