Answer:
PB = 15
Step-by-step explanation:
A midpoint is a point in the center of a line. Since P is the midpoint of AB, the length of AP = PB. Therefore, if AP = 15, PB = 15.
See, please, suggested decision:
When the line intersects the xy-plane, then parameter z=0, when does the xz - y=0 and when does yz, x=0. All the details are in attachment.
If it's possible, check arithmetic part.
Find the total amount in grams.
1 kg = 1000 g
1.4 * 1000 = 1400
So she bought a total of 1400 grams.
Add up the grams she used:
400 + 250 = 650
Subtract it from the total:
1400 - 650 = 750
So 750 grams of sequence were left.
I think the rule has something to do with adding. I noticed that when the input was at 0 the output was 20, When the input was 15 the output was 5, when the input was 8 the output was 12, and so on. I think the rule is, no matter what number is in the input or the output, it must equal 20.
Hope This Helps!
