Answer:
16
Step-by-step explanation:
30-10=20
20 divided by 1.25 = 16
Answer:
a = Negative one-fifth
Step-by-step explanation:
The given equation is :
![\dfrac{2}{5}+a=\dfrac{1}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%2Ba%3D%5Cdfrac%7B1%7D%7B5%7D)
We need to find the value of a.
Subtract 2/5 from both sides.
![\dfrac{2}{5}+a-\dfrac{2}{5}=\dfrac{1}{5}-\dfrac{2}{5}\\\\a=\frac{1}{5}-\frac{2}{5}\\\\a=\dfrac{-1}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%2Ba-%5Cdfrac%7B2%7D%7B5%7D%3D%5Cdfrac%7B1%7D%7B5%7D-%5Cdfrac%7B2%7D%7B5%7D%5C%5C%5C%5Ca%3D%5Cfrac%7B1%7D%7B5%7D-%5Cfrac%7B2%7D%7B5%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B-1%7D%7B5%7D)
So, the correct answer is Negative one-fifth. Hence, the correct option is (b).

Answer:
59 cm
Step-by-step explanation:
The area is the product of length and width. Using the given numbers, we have ...
A = LW
4779 cm² = (81 cm)W
W = (4779 cm²)/(81 cm) = 59 cm
The width of the window is 59 cm.
Answer: $0
Step-by-step explanation:
every six months means the game loses 25%*2 per year = 50%
2 years would be 50%*2 = 100%
Therefore, if the game loses 100% of its value in 2 years, it will be free.
4(x+2)=3(x-2)
Multiply the first bracket by 4
Multiply the second bracket by 3
4x+8=3x-6
Move 3x to the left hand side, whenever moving a number with a letter the sign changes ( positive 3x to negative 3x)
4x-3x+8=3x-3x-6
x+8=-6
Move positive 8 to the right hand side
x+8-8=-6-8
x=-14
Check answer by using substitution method
Use x=-14 into both of the equations
4(-14+2)=3(-14-2)
-56+8=-42-6
-48=-48
Answer is -14- D)
