Determine whether the following statement is true or false. Explain your reasoning. Jordan says that when solving the equation 4

b+3=11, the best first step is to apply the Division Property of Equality.
.

A. The statement is false. Since there is a coefficient on the variable, the Multiplication Property of Equality should be used first.
.
B. The statement is true. The Division Property of Equality should always be the first property of equality used when solving linear equations.
.
C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing.
.
D. The statement is true. Since there is a coefficient on the variable, the Division Property of Equality must be used first.

Answer:

The correct option is;

C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing

Step-by-step explanation:

In other to solve the equation 4·b + 3 = 11, we have;

By the subtraction property of equality, we have;

Firstly we subtract 3 from both sides gives;

4·b + 3 - 3= 11 - 3

Next we apply the division property of equality, we have;

Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,

Dividing both sides by 4, gives;

4·b/4 = 8/4

b = 8/4 = 2

The solution to the equation, 4·b + 3 = 11 is b = 2.

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4)?
Aneli [31]

Answer: 5x + 2y = -2

Step-by-step explanation:

Change 5x+2y=12 to slope intercept: 2y = 12 - 5x, y = -5x/2 + 6

A parallel line has the same slope, so the line we try to find is y = -5x/2 + b.

Substitute (-2, 4) in and get 4=5+b, so b = -1.

Therefore the answer is y = -5x/2 - 1, or if you want it in the original form it would be 2y = -5x - 2 ---> 5x+2y = -2.

Hope that helped,

Select the missing numbers. Remember to indicate a negative cash flow with parentheses.
cluponka [151]

To find the cash flow, subtract the Cash Disbursements from the sales receipts for each month.


January: 110 - 135 =  -$25

February: 85 - 110 = -$25

March: 100 - 95 = $5

April: 130 - 95 = $35

May: 145 - 100 = $45

June: 165 - 105 = $60

Im the diagram shown JKL~ MNP. Find MP and PN.
Vilka [71]

Answer: MP=10, PN=6

Step-by-step explanation:

Corresponding sides of similar triangles are proportional, so:

\\\\frac{MP}{5}=\frac{8}{4}\\\\MP=10\\\\\frac{PN}{3}=\frac{8}{4}\\\\PN=6

It takes 16 minutes for 9 people to paint 8 walls . How many minutes does it take for 4 people to paint 6 walls?
Soloha48 [4]

Answer:

27 minutes to complete the painting of 4 walls

Step-by-step explanation:

since 16m with 9p --> 8 walls

x minutes with 4p --> 6 walls?

let x= minutes

6 walls painted=(8/144 walls painted per minute)x

simplify

x= 6 divided by (8/144)

x=108 minutes (to complete 6 walls)

108/4=

27 minutes to complete the painting of 4 walls
