In this question, the algebra equation is a[3(5b - c)]. Since a = 1.6, b = 2, and c = 5, we would replace the equation into 1.6[3((5)(2) - 5)).

With this equation, the answer will be 24

Answer: 24

Step by Step Explanation:
Since we know what our variables are, we will plug in 1.6 for a, 2 for b, and 5 for c.

1.6[3(5(2) - 5)]

Now we solve and work from the inside out!

1.6[3(10 - 5)]

1.6[3(5)]

1.6 • 15

= 24

So our answer is 24!

Hope this helped! :3

Circle 1 has center (−4, −7) and a radius of 12 cm. Circle 2 has center (3, 4) and a radius of 15 cm.

<h3>Answer with explanation:</h3>

It is given that:

Circle 1 has center (−4, −7) and a radius of 12 cm.

Circle 2 has center (3, 4) and a radius of 15 cm.

Two circles are said to be similar if by some translation and dilation it could be placed over the other to form the same circle.

The circles are similar because the transformation rule ( x,y ) → (x+7,y+11) can be applied to Circle 1 and then dilate it using a scale factor of 5/4

( Since, as the center of circle 1 is (-4,-7)

so,

(-4+7,-7+11) → (3,4)

( Since, the radius of circle 1 is 12 and that of circle 2 is 15 cm.

so, let the scale factor be k .

that means :

$12\times k=15\\\\k=\dfrac{15}{12}\\\\k=\dfrac{5}{4}$ )
