27.6 dollars because if there are 5 small and 7 small that means that 5 plus 7 is 12 and 12 times 2.30 is 27.6

Answer:

5r + (5 x 6) = 84

looking for rice per pound.

Step-by-step explanation:

5r + (5 x 6)  = 84

This shows an equation where we need to make r the subject to establish how many pounds a bag of rice weighs.

5r + (5 x 6)  = 84

5r + (30)  = 84

5r = 84-30

5r = 54/5

r  = 10 4/5  

r  =  10.8 pounds

Manuela solved the equation below.<br><br><br><br> What is the solution to Manuela’s equation?
BabaBlast [244]

For this case we have the following equation:

2 (x + 2) = x-4

Applying distributive property to the terms within the parentheses on the left side of the equation we have:

2x + 4 = x-4

Subtracting "x" on both sides of the equation we have:

2x-x + 4 = -4\\x + 4 = -4

Subtracting 4 on both sides of the equation we have:

x = -4-4\\x = -8

Answer:

x = -8

<h2>(1, 4)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}2x=-y+6&(1)\\-4x+3y=8&(2)\end{array}\right\\\\(1)\\-y+6=2x\qquad\text{subtract 6 from both sides}\\-y=2x-6\qquad\text{change the signs}\\y=6-2x\\\\\text{substitute it to (2):}\\\\(2)\\-4x+3(6-2x)=8\qquad\text{use the distributive property}\\-4x+(3)(6)+(3)(-2x)=8\\-4x+18-6x=8\qquad\text{subtract 18 from both sides}\\-10x=-10\qquad\text{divide both sides by (-10)}\\x=1\\\\\text{put the value of x to (1):}\\\\y=6-2(1)\\y=6-2\\y=4
