Answer:

Step-by-step explanation:

Fatima wrote down 3 square numbers

since we don't know the three square we will represent it by any variable (X)

3x=30

so you divide both sides by 3

so we have 3x/3=30/3=10

therefore the answer is 10

Answer:

1/4

Step-by-step explanation:

the numerator is 12 because there are 12 possible outcomes. The numerator is 3 because there are 3 numbers in this set that are greater than 9. You get 3/12 which then simplifies to 1/4

A window shaped like a parallelogram has an area of 30 square feet. The height of the window is 4

Viefleur [7K]

Answer:

The base of the window is 7.5 feet long.

Step-by-step explanation:

The area of a parallelogram can be found with the formula A = bh

Plug in the known values to get 30 = 4b

30 = 4b

30/4 = b

7.5 = b

Which best describes the relationship between the lines with equations âˆ’3xâˆ’4y=1 and âˆ’6xâˆ’8y=2?

Tju [1.3M]

The relationship between 3x+4y=1 and 6x+8y=2 is that they are parallel lines.

<h3>What is the slope-intercept form of an equation?</h3>

Any linear equation has the form of y=mx+b

m is the slope of the equation

b is the y-intercept

The easiest way to see the relationship between the two lines is to transform them both into slope-intercept form, which is y=mx+b.

Equation 1 can be rewritten as

3x+4y=1

4y=1-3x

y= $\frac{1-3x}{4}$

Equation 2 can be rewritten as:

6x+8y=2

8y=2-6x

y = $\frac{2-6x}{8}$

Y= $\frac{1-3x}{4}$

In this form, we can easily identify that both lines have a slope of $-\frac{3}{4}$ , but that they have different y-intercepts. Lines will equal slopes but different y-intercepts are parallel.

Therefore, the lines are parallel.
