Answer:

$15

Step-by-step explanation:

Let bushes = b and trees = t.

We can write:

12b + 15t = 600 (Equation 1)

8b + 20t = 680 (Equation 2)

24b + 30t = 1200 (Equation 3 -- Multiply Equation 1 by 2)

24b + 60t = 2040 (Equation 4 -- Multiply Equation 2 by 3)

30t = 840 (Subtract Equation 3 from 4)

t = 28 (Divide by 30)

12b + 15 * 28 = 600 (Substitute t = 28 into Equation 1)

12b = 180 (Simplify)

b = 15 (Divide by 12)

What is 3/4 doubled? Is it 6/8 or 1 2/4?

Amanda [17]

Answer:

1 2/4

Step-by-step explanation:

3/4 doubled is $2(\frac{3}{4} )=\frac{3}{2}$

Now, $\frac{6}{8} =\frac{3}{4}$ on simplification.

$1 \frac{2}{4} =\frac{6}{4} =\frac{3}{2}$

Therefore,

3/4 doubled is 1 2/4

The image of the point (6, 6) under a translation is (5,2). Find the coordinates of

Dmitry [639]

9514 1404 393

Answer:

(-1, -2)

Step-by-step explanation:

The difference between the coordinates of the image and the coordinates of the original is the same for both points.

X - (0, 2) = (5, 2) -(6, 6)

X = (5, 2) -(6, 6) +(0, 2) = (5-6+0, 2-6+2)

X = (-1, -2)

The image of the point after translation is (-1, -2).
