Answer:

x=12,y=-8

Step-by-step explanation:

7x=84

x=84/7=12

12y=7x-180=7*12-180=84-180=-96

y=-96/12=-8

The solution of 7x-12y=180 is x = 12 and y =-8.

An equation is made up of two algebraic expressions with the same value and the sign "=" in between.

Given, the equation;

7x-12y=180  {equation 1}

And 7x = 84

x = 84/7

x = 12

Substitute the value of x to the equation 1,

7(12) - 12y = 180

12y = 84 - 180

y = -96/12

y = -8

Therefore, x = 12 and y = -8 is the solution.

Answer:

1/3 and you divide

Step-by-step explanation:

41/2 = 9/2

3/4 ÷ 9/2

3/4 ×2/9 = 6/18

6/18 = 1/3

Answer:

Step-by-step explanation:

Okay. 4 and 1/2 simplifies to the improper fraction, 9/2. And 3/4 of it would mean we MULTIPLY it by the total, 9/2 pounds. (Whenever we see OF, we know that the operation is multiplication.) I think that you can do the rest from here, but I'll include a solution at the bottom if you still need help.

...

(9/2)*(3/4)=(9*3)/(2*4)=27/8=3 and 3/8 pounds of flour used to make brownies.

Hope this helps! Good luck! :)

Answer:

12

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( 60-30)/(6-0)

   = 30/6 = 5

Now using a second set of points and the slope we can find p (0,30) and (p,90)

5 = ( y2-y1)/(x2-x1)

5 = (90-30)/(p-0)

5 = 60/p

Multiply each side by p

5p = 60

Divide by 5

p =60/5

p = 12

Answer:

s ≈ - 0.5 , s ≈ 8.5

Step-by-step explanation:

s² - 8s - 4 = 0 ( add 4 to both sides )

s² - 8s = 4

To complete the square

add ( half the coefficient of the s- term )² to both sides

s² + 2(- 4)s + 16 = 4 + 16

(s - 4)² = 20 ( take square root of both sides )

s - 4 = ± [tex]\sqrt{20}[/tex] ( add 4 to both sides )

s = 4 ± [tex]\sqrt{20}[/tex]

Then

s = 4 - [tex]\sqrt{20}[/tex] ≈ - 0.5 ( to the nearest tenth ) ← smaller solution

s = 4 + [tex]\sqrt{20}[/tex] ≈ 8.5 ( to the nearest tenth ) ← larger solution

Answer:

9 + 4 = $13, Ms. Brown has 10 dollars which is not enough to pay for both Cranberry and Granola.

Step-by-step explanation:

Alright, so Cranberry is 3.25 per pound, and Granola is 2.19 per pound.

(2.9 and 1.75 is how many pounds of both Cranberry and Granola she wants.)

2.9 × 3.25 = 9.4

1.75 × 2.19 = 3.8

So when rounding,  9.4 would be rounded to 9. Then 3.8 would be rounded to 4. So no, Ms. Brown doesn't have enough to pay for both. 9 + 4 = $13

Have a good day friend! :D

Answer:

Let us use the variable "x" to represent the cost per Ib for each mix.

Cranberry: x = 2.9

Granola: x = 1.75

Ms.Brown buys 1.75 pounds of granola and 2.9 pounds of cranberry. Since the cost per pounds represent x, we can write the follow:

[tex]2.19(1.75)+3.25(2.9)[/tex]

[tex]3.83 + 9.42 = 13. 25[/tex]

Round to nearest cent,

Total Cost= $13

Since it is given that Ms.Brown has a $10 budget, she won't have enough for the purchase. She'll need $3 more.
