1. X+Y=44
Y=2(X-A)
Y-A=(X+B/2
X+B= 3(Y-C)
Y-C= 3(X-C)
Solve for X and Y in terms of A, B, and C.
2. Maddux, Smoltz, and Wohlers pitched a total of 576
innings. Maddux pitched 8 2/3 fewer than Smoltz and
167 2/3 more than Wohlers. How many did each pitch?
3. 2 ladders are crossed in an alley. They are
supported by a vertical wall. The ladders are 40
feet and 60 feet in length. They intersect 10 feet
above the ground. How wide is the alley?
4. A banana peel weighs 1/8 the total weight of the
banana. If an unpeeled banana is put on a scale and
it just balances a peeled banana of the same weight
plus 7/8 of an ounce, how much does the banana with
peel weigh?
Please give a detailed explanation with each. Thanks for your assistance.
