Answer:
x=5
Step-by-step explanation:
add 3 to both sides of the equation: -3+3=0 12+3=15 simplified: 6x=3x+15 then subtract 3x from both sides of the equation. simplified: 3x=15
then divide both sides by 3. simplified: x=5
Answer:
Step-by-step explanation:
Given expression is,

By dividing denominator and numerator of the given fraction by m²,

= 
We know that 


Therefore, We can evaluate the limit of the expression by substituting ∞ in for m.
Answer:
y=8x
Step-by-step explanation:
X is the input, Y is the output. The answer describes that whatever X is, if you times it by 8, you get Y. It can't be "x + 14" because that only works with the first number given. If you do Y = X + 14, 6 doesn't equal 48.
I would go with C ( idk the answer i'm just taking an educational guess )
Answer:
x=100°
Step-by-step explanation:
Sum of all angles in a quadrilateral=360
60+x+x+x= 360
60+3x= 360
3x= 360-60
3x=300
x=100
Hope it helps :-)
