4{8.2+3.7(4.4×8.8 -18.86)}=
4(8.2+3.7(38.72-18.86))=
4(8.2+(3.7)(19.86))=
4(8.2+73.482)=
(4)(81.682)=
326.728
Answer:
x=3.5
Step-by-step explanation:

Answer:
y - 13 = (5/2)(x - 4)
Step-by-step explanation:
Here we know the slope and one point on the line. Use the point-slope formula:
y - k = m(x - h).
Substituting 13 for k, 4 for x and 2.5 for m, we get:
y - 13 = (5/2)(x - 4)
