Answer:
a= 18x
Step-by-step explanation:
(a+d)/2 = 10x (1)
(b +c)/2 = 8x (2)
(b+c+d)/3 = 6x (3)
From the equation 2, we have (b+c)= 8x *2 = 16x
From the equation 3, we have d= 6x*3 - (b+c)= 18x- 16x = 2x
From the equation 1, we have a= 10x*2 -d= 20x - 2x= 18x
You divid the top by the bottom and get 8.8571

Answer:
about 7.61%
Step-by-step explanation:
Put the given numbers into the formula and solve for r.
2200 = 1900(1 +r)^2
√(22/19) = 1 +r
r = √(22/19) -1 ≈ 0.076055 ≈ 7.61%
For this case we must indicate an expression equivalent to:

By definition we have that the distributive property establishes that:

Then, applying the property to the given expression we have:

Thus, an equivalent expression is:
