Equation below
5+3(2x - 7) = 5 + 6x - 21​

True for all x

Any number

Step-by-step explanation:

It's True

Step-by-step explanation:

Let's solve your equation step-by-step.

5+3(2x−7)=5+6x−21

Step 1: Simplify both sides of the equation.

5+3(2x−7)=5+6x−21

5+(3)(2x)+(3)(−7)=5+6x+−21(Distribute)

5+6x+−21=5+6x+−21

(6x)+(5+−21)=(6x)+(5+−21)(Combine Like Terms)

6x+−16=6x+−16

6x−16=6x−16

Step 2: Subtract 6x from both sides.

6x−16−6x=6x−16−6x

−16=−16

Step 3: Add 16 to both sides.

−16+16=−16+16

0=0

All real numbers are solutions.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

answer: options
