Step-by-step explanation:
Meredith and Hillary both want coffe, but they don't know if the other two people do, therefore they can't know if everyone want coffee. If they didn't want coffee, their answer would have been just "no".
Aly knows that she doesn't want coffee, therefore she knows that not everyone wants coffee.
Answer: so what you would do is would would take the first number that being -2 and add it to the problem like this y=2(-2)+1 and what you do is you times 2 and x2 which give you -4 then you add 1 which gives you -3 so y = -3
Step-by-step explanation:
Y=2(-2)+1 Y=2(-1)+1
-4+1 -3+1
-3 -2
y=2(0)+1 Y=2(1)+1
0+1 2+1
0 3
y=2(2)+1
4+1
5
Answer:
x = 1/21
Step-by-step explanation:
7 = 3/9x
Multiply both sides by 9x
7 x 9x = 3/9x x 9x
9x cancels out on the right side
63x = 3
Divide both sides by 63 to isolate x
63x/63 = 3/63
x = 1/21
For one set the two equations equal to eachother and solve from there. 2 is 45
For three set the two equations equal. Same for four
Answer:
Step-by-step explanation:
That will be the perimeter. Perimeter is the distance around. Add all five sides, be sure to put the unit behind.
