Answer:
x=9.8
Step-by-step explanation:
Answer:
d = 1
Step-by-step explanation:
The equation given is:
0.5(7d + 4) = 7 - 1.5d
Expand the bracket:
3.5d + 2 = 7 - 1.5d
Collect like terms:
3.5d + 1.5d = 7 - 2
5d = 5
d = 5 / 5 = 1
Answer:
82
Step-by-step explanation:
f(x) = 5x - 3
g(x) = 2x + 9
f(g(x)) = 5 (2x + 9) - 3 ..... replace x with g(x)
f(g(4)) = 5 * (2 * 4 + 9) -3 = 85 - 3 = 82
3^2 * 3^5 =
3*3=9 * 3*3*3*3*3= 243
I think you can figure out it from there
