Answer:
x = 
Step-by-step explanation:
Given
x + 2 = 
Multiply through by 16 to clear the fractions
10x + 32 = 57 ( subtract 32 from both sides )
10x = 25 ( divide both sides by 10 )
x = 
=
Answer:
1 2 3 4 5 6 7 8 A
Step-by-step explanation:
63 - 2.95 = 60.05
Rounding using significative figures
63 has three significative figures
2.95 has three
So, we must round the result to 2 significative figures.
Result = 60
Answer:
y=0.5x+4
Use y2-y1/x2-x1 to find the slope:
3-6/-2-4
Sub in the x and y-values into y=0.5x+b
6=0.5(4)+b
Solve and b=4
