Answer:
percent error=6%
Step-by-step explanation:
Step one:
given data
Patty counted 250
The actual amount of chocolate chips on the tray were 265
Required
The percent error
Step two:
The formula is
percent error= actual-expected/expected*100
percent error= 265-250/250*100
percent error=15/250*100
percent error=0.06*100
percent error=6%
Answer:
Step-by-step explanation:
3h - 8h + 10 = 10 - 5h
-5h + 10 = 10 - 5h
10 = 10

Answer:
The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is 
Step-by-step explanation:
The standard form of equation is 
Finding slope
Using the given points (0,-4) and (-3,-2) we can find slope using formula:

Finding y-intercept
Using point (0,4) and Slope=-2/3 we can find y-intercept

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

Now, standard form of equation will be: 
So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is 
The answer to your problem will be 16
Answer:
x = -1/2
Step-by-step explanation:
2x + 4y = 13
3x + y = 2 (you can multiply this equation by -4 in order to eliminate the y-term)
-4(3x + y = 2) = -12x - 4y = -8
+ <u>2x + 4y = 13</u>
-10x = 5
x = -5/10 or -1/2
x(-1/2) + 4y = 13
-1 + 4y = 13
4y = 14
y = 14/4 or 7/2 or 3 1/2
