X=4.5
5-7.25=-2.25
-2.25/-0.5=4.5
x=4.5

Ok so first you need to subtract 7.25 from both sides

-2.25=-0.5x

Then divide by -0.5

Which gives you

x=4.5

Hope this helps.

Answer:

$y=-\frac{5}{2}x+\frac{11}{4}$

Step-by-step explanation:

To find a line perpendicular to 2x - 5y = 20, we need to find the slope of the line. To get the slope, we can solve for y, and get the equation in the form of y=mx + b

So I will solve for y:

$2x - 5y = 20\\\\-5y=-2x+20\\\\y=\frac{2}{5} x-4$

So we know the slope is 2/5

The slope of a perpendicular line is the oposite reciprocal of original line. So the oposite reciprocal of 2/5 is -5/2. That will be our new slope

Now that we know the slope we can use the point slope formula to find an equation, then solve for y.

y-y₁=m(x-x₁)

y-4 = -5/2(x+ 1/2))

y= -5/2x + 11/4

Identify an equation in slope-intercept from for the line parallel to y=-3x + 7 that passes through (2, -4)

alexandr1967 [171]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

The parallel lines have the same slope.

We have y = -3x + 7 → m = -3. Therefore y = -3x + b.

Put the coordinates of the point (2, -4) to the equation of a line:

$-4=-3(2)+b$

$-4=-6+b$ add 6 to both sides

$2=b\to b=2$

<h3>Answer: y = -3x + 2</h3>

bekas [8.4K]

Rectangles that are 5×20, 6×12, or 8×8 will satisfy your criteria. The sum of the areas of those is 236 units².

_____
20×5 and 12×6 rectangles are also "cool", but their areas are not different from those already counted.

A horse takes 3 steps to walk the same distance for which a goat takes 4 steps. Suppose 1 step of the dog covers 1/2 of a metre.

almond37 [142]

Answer:

The goat would cover 9 meters in taking 24 steps.

Step-by-step explanation:

There is a mistake in the question so the correct question is below:

A horse takes 3 steps to walk the same distance for which a goat takes 4 steps. Suppose 1 step of the horse covers 1/2 of a metre. How many metres would the goat cover in taking 24 steps?

Now, to find the meters goat cover in taking 24 steps.

As 1 step of horse covers = $\frac{1}{2} \ meter.$
