Answer/Step-by-step explanation:
1. ; 3
Let's solve for a.
(subtraction property of equality)
(division property of equality)
Therefore, 3 is a solution to 9 = 2a + 3
2. ; 7
(- × - = +)
(Subtraction property of equality)
(division property of equality)
Therefore, 7 is not a solution of
3. ; 1
Therefore, 1 is a solution of .
We have been given that a rectangle has a height to width ratio of 3:4.5.
Let h be height and w be width of rectangle.
We can set our given information in an equation as:
Now we will substitute h=1 in this equation.
We can see that width of rectangle is 1.5 times height of rectangle.
Our one set of dimensions of rectangle will be: height=1 and width=1.5.
We can get many set of dimensions for our rectangle by multiplying both height and width of rectangle by same number.
Multiplying by 5 we will get our dimensions as: height 5 and width 7.5.
Therefore, (1 and 1.5) and (5 and 7.5) dimensions for rectangle will be scaled version of our rectangle.
