Answer:
42
Step-by-step explanation:
Angles on a line add up to 180 so
180 - 92 = 88
Thats angle y
Now the angles in a triangle add up to 180 so
50+88+x = 180
138 + x = 180
x = 42
Answer:
4.13E23 molecules
Step-by-step explanation:
Molar mass HCl = 36.4611 g/mol
25.0g = 25/36.4611 = 0.686 mol HCl
1 mol HCl = 6.022*10^23 molecules
0.686 mol = 0.686*6.022*10^23 = 4.13*10^23 molecules.
Answer:
y=-3/4x+3
Step-by-step explanation:
the slope is -3/4
in this case, y=mx+b
so y=-3/4x+b
b is the y intercept, so it would be 3
altogether, y=-3/4x+3
