Solving steps:

3x - 9y = -18

divide both sides by 3

3x - 18 + 9y

therefore, x = 6+3y

We cannot solve this further, therefore x = 6 + 3y

Determine the equation of the circle graphed below.

Rzqust [24]

Answer:

Step-by-step explanation:

(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2}(x−h)

+(y−k)

here

r = 7. (the circle is symmetrical with y - axis )

h = 0. and k = 1

Thus equation of circle is,

(x - 0) {}^{2} + (y - ( - 1)) {}^{2} = {7}^{2}(x−0)

+(y−(−1))

x^2 + (y+1)^2 = 49

Maggie buys 1 1/2 pounds of walnuts pounds of walnuts 8 ounces 8 ounces of pecans of pecans and 3/4 pounds of almonds how much d

svetlana [45]

Answer:

$2\frac{3}{4}$ pounds

Step-by-step explanation:

Maggie buys 1 1/2 pounds of walnuts, 8 ounces of pecans and 3/4 pounds of almonds.

To find the total weight of nuts that she buys, let us first put all the weights in a single unit, pounds.

She buys 8 ounces of pecans.

1 ounce = 0.0625 pounds

8 ounces = 8 * 0.0625 = 0.5 pounds = 1/2 pounds

Therefore, the total weight of nuts that she buys is:

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

The nuts weight $2\frac{3}{4}$ pounds in all.
