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.
$______ was loaned at 14%.
Answer:
$7 000 was loaned at 10 % and
$10 500 was loaned at 14 %
Step-by-step explanation:
Let x = amount loaned at 10 %
Then 17 500 - x = amount loaned at 14 %
0.10x = interest on 10 % loan
0.14(17 500 - x) = interest on 14 % loan
2170.00 = total interest
$7000 was loaned at 10 % and
$10 500 was loaned at 14 %

OK.
Answer:
Proceed the next step, then. Whether it is sum/subtract the addends, whether it is subtract. Then isolate the variable, aiming to find out the quantity of x.
Step-by-step explanation:
If an equation whose product does not need the distributive property, then the factors have already been distributed. And
Visualizing it
Suppose the following equation:
Now let's focus the following step, that point of the question, when the equation does not need the distibutive property:
3x +6=4
3x+6 -6=4-6
3x=-2
3x/3=-2/3
x=-2/3
S={-2/3}
I believe that the answer would be C. 1.3 seconds
Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ○ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2
