Answer:
5x - (x/y) = 18 when x=4 and y=2
Step-by-step explanation:
5x - (x/y)
When x=4 and y=2
Substitute the value of x=4 and y=2 into the expression
5x - (x/y)
5(4) - (4/2)
Multiply 5 by 4 and divide 4 by 2
=20 - 2
Subtract 2 from 20
=18
5x - (x/y) = 18 when x=4 and y=2
9. 1/2 x 8 x 10 = 40 in²
10. 1/2 x 7 x 9 = 31.5 yd²
11. 1/2 x 12 x 8 = 48 cm²
12. 1/2 x 3 x 16 = 24 ft²
