By the Addition Principle of Equality, I would add 3.4 to both sides of the equation to get rid of the constant term -3.4 on the right-hand side.

12.7 + 3.4 = j - 3.4 + 3.4
16.1 = j

So, j is equal to 16.1.

12.7 = j - 3.4

We're simply just trying to get j by itself.

So, add 3.4 to both sides.

12.7 + 3.4 = j

Simplify.

16.1 = j

So, j = 15.1

~Hope I helped!~

1- Caleb's family room has the dimensions shown. He needs to find the area of the room so that he knows how much carpet to buy.

Rina8888 [55]

Answer: $20\frac{11}{32}\ sq\ yd$

Step-by-step explanation:

Given: The width of the room = $3\frac{7}{8}\ yd=\frac{31}{8}\ yd$

The length of the room = $1\frac{5}{4}\ yd=\frac{21}{4}\ yd$

The area of the rectangular room= $length \times width$

⇒The area of the rectangular room= $\frac{21}{4}\times\frac{31}{8}\ sq\ yd$

⇒The area of the rectangular room= $\frac{651}{32}\ sq\ yd$

⇒The area of the rectangular room= $20\frac{11}{32}\ sq\ yd$

Solve. Enter your answer as a mixed number. The driving distance from the sports arena to Kristina's house is 11 7 10 miles. The

sineoko [7]

Answer: $6\frac{1}{2} miles$

Step-by-step explanation:

From the sports arena to Kristina's house = $11\frac{7}{10}miles$

From the sports arena to Luke's house = $5\frac{2}{10} miles$

Subtract Luke from Kristina

$5\frac{2}{10}-11\frac{7}{10}$

There's a confusing but easy way to solve this. However, I'm going to convert into improper fractions to make it easier.

To convert to improper fraction, take the whole number, multiply it by the denominator and add it to the numerator. All over the same denominator.

$\frac{5*10+2}{10} -\frac{11*10+7}{10}$

$\frac{50+2}{10}-\frac{110+7}{10}\\\frac{52}{10}-\frac{117}{10}$

Subtract them.

$\frac{52-117}{10}$

$-\frac{65}{10}$

Convert to mixed number by dividing.

65/10=6

60

----

5

The 6 is the whole number, 5 the numerator and 10 the denominator. Remember the negative sign that we had.

$6\frac{5}{10}$

5 and 10 can be simplified

5/5=1

10/5=2

Our final answer would be:

$6\frac{1}{2}$

What is the equation of the line that passes through the point (-4,4)(−4,4) and has a slope of -3−3?

drek231 [11]

Answer:

<h2> <u>y = -3x - 8</u></h2>

Step-by-step explanation:

The equation of the line that passes through the point <em>(x₁, y₁)</em> and has a slope of <em>m</em> in point-slope form is: y - y₁ = m(x - x₁)

m = -3

(-4, 4) ⇒ x₁ = -4, y₁ = 4

Therefore:

y - 4 = -3(x - (-4))

<u>y - 4 = -3(x + 4) </u><u> </u> ← point-slope form

y - 4 = -3x - 12 {add 4 t both sides}

<u>y = -3x - 8 </u> ← slope intercept form
