Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
The multiplication that takes place while distributing comes before addition and subtraction in order of operations.
In order to combine like terms on one side of the equation, the inverse operation must be used.
When the problem is worked in the correct order, the numbers that Maricella added are not actually like terms.
Maricella did not combine all three constants on both sides of the equation; she combined only two.

8, It will be a whole number.

A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth.

Answers

Answer: 2.9 minutes.

Step-by-step explanation:

Given: Rate of filing the tank =  12 gallons per minute

Total volume of reservoir = 35 gallons

Time taken to fill the reservoir = [tex]\dfrac{\text{Total volume of reservoir }}{\text{Rate of filing the tank}}[/tex]

[tex]=\dfrac{35}{12}\approx2.9[/tex]

hence, time taken to fill the reservoir = 2.9 minutes.

2. (-4k -1) -(-6k -6) = -4k -1 +6k +6 = (-4+6)k +(-1+6)

  = 2k +5

3. (-6k +7) -(7k +5) = -6k +7 -7k -5 = (-6-7)k +(7-5)

  = -13k +2

Determine any data values are missing from the table assuming that the data represents a linear function.

Answers

Answer:

Missing x:0

Missing y:1

Hence, option b is correct.

Step-by-step explanation:

Given the table

x                          y

-9                         3

-6                          2

-3                          missing

missing                  0

As we know that the linear function has a constant common difference between the x values and y values.

From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by -3.

i.e. -9-(-6)=-3

-6-(-3)=-3

So the missing x value will be:

-3-(x)=-3

-3-(0)=-3

Therefore, the missing x value wil be: 0

From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by 1.

i.e.

3-2=1

2-y=1

y=1

Therefore, the missing y-value will be 1.

Therefore,

Missing x:0

Missing y:1

Hence, option b is correct.
