Answer: I think
Step-by-step explanation:Let the coordinate of the point be (x,y,z). Since the point is located 3 units behind the YZ− plane, 4 units to the right of XZ− plane and 5 units above the XY−plane ,x=−3,y=4 and z=5 Hence, coordinates of the required points are (−3,4,5)
Answer:
Step-by-step explanation:
x + 0.7 = 1 - 0.2x
Add 0.2x to both sides
x + 0.2x + 0.7 = 1 - 0.2x + 0.2x
1.2x + 0.7 = 1
Subtract 0.7 from both sides:
1.2x + 0.7 - 0.7 = 1 - 0.7
1.2x = 0.3
Divide both sides by 1.2:
1.2x/1.2 = 0.3/1.2
x = 0.25

Answer:
Number 1 :If you are using a calculator, simply enter 40×100÷17, which will give you the answer.
Number 2: 45 percent of 155 is 69.75.
Number 3: 137 is what percent of 153? = 89.54
First, multiply the 2 times (x-5) and you get 2x-10 on the left side.
Then on the right side, add up all the similar terms and you get 30 (the -3x and +3x cancel each other out.
2x-10=30
Then add 10 to both sides and you get 2x=40.
Then divide both sides by 2 and you get x=20.
Answer is B.
