Answer:
14.5
Step-by-step explanation:






Answer:
50.2 m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius , here r = 4 ), thus
A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )
Answer: no solution
Step-by-step explanation:
7x + 5 + 5x = 15x - 7 - 3x + 2
12x + 5 = 12x - 5
-12x -5. -12x -5
0 = -10
no solution
Answer:
t = 1
Step-by-step explanation:
16 - 2t = t + 9 + 4t; move numbers and t's
-16 -16 ; subtract 16 from both sides
-2t = 5t -7 ; subtract -5t from both sides
-5t -5t
--------------
-7t = -7 ; divide by -7
t = 1
2p = 4
p = 2
-2p = 4
p = -2
answer p = -2 and p =2
