Answer:
B. w = 4
Step-by-step explanation:
As we know, in a parallelogram length of opposite sides are equal.
so, AD = BC
⇒ 4w - 5 = 7w - 17
⇒ 12 = 3w
⇒ w = 4
For an instance, i stands for the money that you have, and b stands for the money that brother has.
An equation system based on the problem would be
i + b = 42 (equation 1)
i = 3b (equation 2)
Use substitution method to solve the problem
substitute 3b into i in the equation 1
i + b = 42
3b + b = 42
4b = 42
b = 42/4
b = 10.5
substitute the value of b into the equation 1
i = 3b
i = 3(10.5)
i = 31.5
You have $31.5 and your brother has $10.5
