9 x 9 x 9 is 729, so to make it 279 you can switch the two and seven around. Hope I helped. (IT IS IMPOSSIBLE TO GET 279 FROM 9 x 9 x 9 )

1200+0.0005x=1500+0.0015x

Daniel [21]

Answer:

X=-300000

Step-by-step explanation:

Move variable to the left-hand side

1200+0.005x-0.0015x=1500

Move the constant to the right-hand side and change sign

0.005x-0.0015x=1500-1200

Combine like terms

-0.001x=1500-1200

Subtract the numbers

-0.001x=300

Divide both sides of the equation by -0.001

X=-300000

Write an equation for a line that is parallel to the graph of y = -3x + 6 and passes through the point at (-4, 7)

ale4655 [162]

Y = -3x + 6....the slope here is -3. A parallel line will have the same slope.

y = mx + b
slope(m) = -3
(-4,7)....x = -4 and y = 7
now we sub into the formula and find b, the y int
7 = -3(-4) + b
7 = 12 + b
7 - 12 = b
-5 = b
so ur parallel equation is : y = -3x - 5 <==

A baker buys 19 apples of two different varieties to make pies. The total cost of the apples is $5.10. Granny Smith apples cost

Natasha2012 [34]

The baker bought 7 gala apples, and 12 granny smiths apples

Solution:

Let "x" be the number of gala apples bought

Let "y" be the number of granny smith apples bought

Cost of 1 gala apple = $ 0.30

Cost of 1 granny smith apple = $ 0.25

A baker buys 19 apples of two different varieties to make pies

Therefore,

number of gala apples bought + number of granny smith apples bought = 19

x + y = 19 --------- eqn 1

The total cost of the apples is $5.10

Therefore, we can frame a equation as:

number of gala apples bought x Cost of 1 gala apple + number of granny smith apples bought x Cost of 1 granny smith apple = 5.10

$x \times 0.30 + y \times 0.25 = 5.10$

0.3x + 0.25y = 5.1 -------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 19 - y ---------- eqn 3

Substitute eqn 3 in eqn 2

0.3(19 - y) + 0.25y = 5.1

5.7 - 0.3y + 0.25y = 5.1

5.7 - 0.05y = 5.1

0.05y = 5.7 - 5.1

0.05y = 0.6

y = 12

Substitute y = 12 in eqn 3

x = 19 - 12

x = 7

Thus the baker bought 7 gala apples, and 12 granny smiths apples
