Answer:

b = -9

Step-by-step explanation:

1. Move the variables to the left side. Be sure to change the terms (add/subtract)

-9b-6 = -3b+48

-9b+3b-6 = 48

2. Combine like terms.

-9b+3b-6 = 48

-6b = 48 + 6

3. Divide both sides by -6.

-6b = 54

b = -9

Answer:

b=-9

Step-by-step explanation:

Given Equation:

-9b-6=-3b +48

Taking the terms of variable 'b' to one side and the constants to the other side:

Adding '3b' both the sides:

-9b+3b-6=-3b+3b +48\\\\-6b-6=48

Adding '6' both the sides:

-6b-6+6=48+6\\\\-6b=54

Dividing by '-6' both the sides:

b=\dfrac{54}{-6}\\\\ b=-9

The solution of the equation is :  b=-9

A rectangular picture frame has a length of that is 6 more than its width the perimeter of the frame is 52 inches. what is the l
Hitman42 [59]

Answer:

Width = 10 and Length = 16

Step-by-step explanation:

→ Assign variables to the length and width

width = x so length = 6 + x

→ Make an equation

x + 6 + x + x + 6 + x = 52

→ Simplify

4x + 12 = 52

→ Minus 12 from both sides

4x = 40

→ Divide both sides by 10

x = 10

→ Resubstitute into the previously assigned values

width = 10 so length = 16

The accompanying data are the caloric contents and the sugar contents (in grams) of 11 high-fiber breakfast cereals. Find the eq
Slav-nsk [51]

The regression equation based on the information given about the sugar contents will be 0.18x - 20.84.

<h3>How to explain the regression?</h3>

It should be noted that from the information, the accompanying data are the caloric contents and the sugar contents of 11 high-fiber breakfast cereals.

The sugar content will be:

a. 160 calories

= 0.18x - 20.84.

= 0.18(160) - 20.84

= 7.96

b. 90 calories

= 0.18x - 20.84.

= 0.18(90) - 20.84

= -4.64

c. 175 calories

= 0.18x - 20.84.

= 0.18(175) - 20.84

= 10.66

d. 208 calories

= 0.18x - 20.84.

= 0.18(208) - 20.84

= 16.6

Therefore, the sugar contents is illustrated above.

A car seller buys a car from a manufacturer for $10,000. He increases the cost by 5 percent. What is the markup amount?
torisob [31]
We know that:

The markup is the price added to the cost price of goods...

To find the markup, we must multiply the percent increase by the original price (before markup).

So:

10,000 x 5% (or 0.05) = ?

10,000 (You do not have to follow my way of multiplying, do what is comfortable for u)
x       5 (Ignore the decimals then we move it after we get the answer) 
----------
50,000 move the decimal back 2 places so it is 500

The final answer is:

The markup amount is $500...
