-3.4 + (-8 + 2) = ( _ + (-8) + 2)
-3.4 + (-6) = ( _ + (-8) + 2)
-9.4 = ( _ + (-8) + 2)
-9.4 = ( _ + -6)
Now remember whatever you do to one side you have to do to the other. :)
-9.4 - -6 = -6 - -6
= -3.4
You had to do one side of the equation before you could do the other side because you needed an answer to follow.
Answer:
Step-by-step explanation:
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
Answer:
Fraction 81/100
Decimal .81
Percent 81%
Step-by-step explanation:
There are total 10×10 = 100 squares in the picture and number of shaded squares = 100 - 19 = 81
Shaded area expressed as the fraction of the whole =
Shaded area in decimals of the whole =
Shaded area in percent of the whole = = 81%
Answer:
The answer is 0.75x.
Step-by-step explanation:
If the dress is on sale for 25% off, then we know that the new sale price of the dress is x - (25/100)x = x - 0.25x = 0.75x.
