Answer:

The answer is 7/24.

Step-by-step explanation:

I attached a picture, but I'll try to walk through it here.

1) A negative and a negative makes a positive, so h becomes positive.

2) I added 7/8 to both sides, in order to "isolate the variable", which simply means to get h by itself, on one side of the equation (you'll likely hear it said both ways).

3) I multiplied 7/8 by 3/3, and multiplied -7/12 by 2/2. This is known as a common denominator, which in this case is 24. You can only add and subtract fractions that have a common denominator.

4) Multiply both of the fractions to get 21/24 + (-14/24). "Adding a negative" is the same thing as subtracting.

5) 21 - 14 = 7, and since our denominators are the same, the answer is 7/24.

You can confirm the answer by substituting, or "plugging" 7/24 into your original equation, in place of h.

Slope = -2/5, contains the point (10,3)

Daniel [21]

Answer: if this is supposed to be in slope-intercept form

the equation would be: y = -2/5x + 7

Step-by-step explanation:

so the slope is: -2/5 and the point is (10,3) considering that x = 10 and y = 3

so we would plug this information into this equation: y = mx + b (slope-intercept form)

3 = -2/5(10) + b

3 = -4 + b

b = 7

and if we plug this in:

y = -2/5x + 7

St. Augustine grass can grow at the rate of 4 over 7 centimeter per week.

kotegsom [21]

Given, the rate of growth of St. Augustine grass is $\frac{4}{7}$ cm per week.

We have to find the number of weeks that the grass grow to $\frac{12}{7}$ cm.

Let's take the number of weeks be x.

In 1 week the grass grow = $\frac{4}{7}$ cm

So in x weeks the grass grow = $(\frac{4}{7}) (x) =\frac{4x}{7}$ cm

So we can write,

$\frac{4x}{7} =\frac{12}{7}$

To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,

$(\frac{4x}{7}) (7) =(\frac{12}{7})(7)$

$4x =(\frac{12}{7})(7)$

$4x = 12$

Now to get we will move 4 to the right side by dividing it to both sides. We will get,

$\frac{4x}{4} =\frac{12}{4}$

$x = 3$

So we have got the required answer.

After 3 weeks the grass grow $\frac{12}{7} cm$ .

A sweatshirt with a regular price of $34 is first discounted by 20% and then by an additional 10%. What is the final sale price?

Ipatiy [6.2K]

Price of the sweatshirt = $34

First discount = 20% x $34 = 0.1 x 34 = $6.80

Price after discount = $34 - $3.40 = $27.20

Additional discount = 10% x $27.20 = $2.72

Price after additional discount = $27.20 - $2.72 = $24.48

Answer: FInal sale price = $24.48
