One way is to move the 4 to other side so it would be x = 13 - 4 and that's x = 9
Answer:
a=16400 feet
Step-by-step explanation:
t = -0.0035 a +g
-17.40 = -0.0035 a+40
-17.40-40=-0.0035a+40-40
-57.40=-0.0035a
a = -57.40/-0.0035
a=16400 feet
Answer:
172 g/mol
Step-by-step explanation:
CaSO4 . 2H2O
Atomic mass of
Ca = 40
S = 32
O = 16
H = 1
Molar mass = 40 + 32 + (16×4) + 2{(1×2)+16}
= 72 + 64 + 2(18)
= 136 + 36
= 172 g/mol
Can you send the picture so I know what you need help with.....
To find the slope you do y1-y2/x1-x2
To find the y intercept you look at when x is zero what is y.
Equation is y=-1/2x -2
