Question

1. Evaluate the following when d = 35, g = 199, and h = 6.

(d + g)
h

2. Evaluate the following when w = 5.4, x = 0.5, and p = 1.8.
wx/p + p/x

Answer 1

d = 35, g = 199, and h = 6.
(d + g)h
Next step, substitute d with 35, g with 199, and h with 6 into (d+g)h

(d+g)h
=(35+199)6
=(234)6
=1404. Lastly, (d+g)h=1404 when d=35, g=199 and h=5
2/
w = 5.4, x = 0.5, and p = 1.8.
wx/p + p/x
Do the same to this by substitute w with 5.4, x with 0.5, and p with 1.8 in wx/p+p/x
wx/p+p/x
=5.4(0.5)/1.8+1.8/0.5
=2.7/1.8+3.6
=1.5+3.6
=5.1. As a result, wx/p+p/x=5.1 when w=5.4, x=0.5 and p=1.8. Hope it help!

Answer 2

1. (35 + 199) * 6
evaluate the parentheses first:-

= 234 * 6 = 1404

2. (5.4 * 0.5) / 1.8 + 1.8 / 0.5

= 2.7 /1.8 + 3.6

= 1.5 + 3.6

= 5.1
