different types of coins there are. All we know is that all 10 of them
on the scale at the same time have 45 grams of mass.
IF all the coins happen to be identical ... AND each one is worn down
the same amount, AND each one has the same amount of dirt and oil
on it ... then each one has (45/10) = 4.5 grams of mass.
But those are some big IFs.
There are 4.5 grams in each coin.

Answer: 4
Step-by-step explanation:
Given: The length of a model locomotive = 18 inches
The length of a exact locomotive = 72 inches
The scale factor to scale the model of the locomotive is given by the ratio of the length of the locomotive to the length of the model.
let k be the scale factor, then
Hence, the dimensions of the locomotive model is 4 times the dimensions of the model.
Therefore, the locomotive is 4 times wider than a window on the model.
ratio:
or:
so window is 48 times wider normaly than in this model

0.53 = 64/121
sqrt (0.53) = sqrt (64)/ sqrt (121) = 8/11 = 0.7273
Therefore sqrt (53) = 10 * 0.7273 = 7.27
sqrt (108) = 10 * sqrt (1.08)
sqrt (1.08) = sqrt (676/625) = 26/25 = 1.04
Therefore sqrt (108) = 10 * 1.04 = 10.4
sqrt (128) = 10 * sqrt (1.28)
sqrt (1.28) = sqrt (289/225) = 17/15 = 1.133
Therefore sqrt (108) = 10 * 1.133 = 11.33

Answers
get the equation in slope intercept form
2x-3y=9
subtract 2x from each side
-3y = -2x +9
divide by -3
y = 2/3 x -3
slope = 2/3
y intercept = -3
x intercept set y=0 and solve
0 = 2/3 x -3
add 3 to each side
3 = 2/3 x
multiply each side by 3/2
9/2 = x
the x intercept is 9/2 or 4 1/2
y=(2x-9)/3
y=(2/3)x-3
slope(m)=2/3
finding x-intercept..
if y=0
2x-3(0)=9
x=9/2
finding y-intercept..
if x=0
2(0)-3y=9
y=-3
