Answer:
4 3/8
Step-by-step explanation:
1. We can use the formula
<em>Area = L (length) x W (width)</em>
2. The area is unknown so we can substitute it for<em> a</em>
<em> </em>The length and width are both known, so we can plug them in.
<em>a= 2 1/2 x 1 3/4</em>
3. Solve by multiplying
<em>a=4 3/8</em>
Answer:
C) x=2 y=-1 z=3
Step-by-step explanation:
2x + y - z = 0
2(2) + (-1) - (3) = 0
0 = 0
x - y + z =6
2 - (-1) + 3 = 6
6 = 6
x + 2y + z = 3
2 + 2(-1) + 3 = 3
3 = 3
