Which best describes the solution to 4 minus 7?
Basile [38]

Answer:

The answer would be "because 4 + (negative 7) is an equivalent expression, the answer is –3".

Step-by-step explanation:

First of all, determine if the answer is going to be positive or negative by seeing the sign of the greater number (that would be 7). So, the answer would be negative. Then do the expression using absolute values; 7-4=3. Now, just add the negative sign before 3 and that's it. You did it! Please rank Brainliest if this helps. Thank you!

A rectangle has a height to width ratio of 3:4.5. Give two examples of dimensions for rectangles that could be scaled versions o
OlgaM077 [116]

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:

\frac{h}{w} =\frac{3}{4.5}

h=\frac{3}{4.5} *w

Now we will substitute h=1 in this equation.

1=\frac{3}{4.5} *w

3w=4.5

w=\frac{4.5}{3} =1.5

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.
