Answer:
Step-by-step explanation:
12 x + 4 y = 42 .............1
16 x + 8 y = 64 .............2
Eliminate y
multiply (1)by -2
Multiply (2) by 1
-24 x -8 y = -84
16 x 8 y = 64
Add the two equations
-8 x = -20

Answer:
D
Step-by-step explanation:
for example point (2,0) is one of the solutions.
=> x + 2y <4
2+ 2(0) = 2 => 2< 4 (true)
=> 3x – y > 2
3(2)-0= 6 => 6>2 (true)
so, the option D is the correct one
Answer:
3.14 x 3.5 - 5 x 20
Step-by-step explanation:
The radius is like circumference just multiply the base number by the pi to get the answer.
To evaluate, we need to follow the order of operations. Below are the steps taken in order:
16 * 3 + [(17 - 3) / 2] - 43
16 * 3 + [14 / 2] - 43
16 * 3 + 7 - 43
48 + 7 - 43
55 - 43
12
Therefore the answer is 12.
