Answer:

Step-by-step explanation:

a n

---- = ---- Solve for a. Note that if we multiply both sides of this equation by

m p n

m, we get a = m * ----

m*n

and this simplifies to a = mn/p or a = ---------

#7 Solve mx = np for x. We want to isolate x on the left side. Dividing

both sides by m isolates x on the left and adds the divisor m on the right:

mx = np => x = ------

#8 Solve c - x = d + r for x We want -x alone on the left side. Accomplish this by subtracting c from both sides, obtaining:

-x = d + r - c. Now multiply both sides by -1, obtaining x = -d - r + c

The boundary lines for the system of inequalities is given in the graph.

diamong [38]

Answer:

region C

Step-by-step explanation:

We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:

$\displaystyle y ≤ -x + 2$

0 ≤ 2 ☑ [We shade the portion of the graph that CONTAIN THE ORIGIN, which is the bottom portion.]

$\displaystyle y ≥ 2x - 3$

0 ≥ −3 ☑ [We shade the portion of the graph that CONTAINS THE ORIGIN, which is the left side.]

So, now that we got that all cleared up, we can tell that both graphs share a region where the ORIGIN IS VISIBLE. Therefore region C matches the above inequalities.

I am joyous to assist you anytime.

The area of a square is given by x2, where x is the length of one side. Mary's original garden was in the shape of a square. She

Vinil7 [7]

Answer:

$128\text{ ft}^{2}$

Step-by-step explanation:

We have been given that the area of a square is given by $x^2$ , where x is the length of one side.

Mary's original garden was in the shape of a square. She has decided to double the area of her garden. So the new area of Mary's garden will be 2 times the area of original garden.

We can represent this information in an equation as:

$\text{Area of Mary's new garden}=2x^{2}$

Therefore, the expression $2x^2$ will represent the area of Mary's new garden.

To evaluate the area of new garden, if the side length of Mary's original garden was 8 feet, we will substitute x equals 8 in our expression.

$\text{Area of Mary's new garden}=2(8\text{ ft})^{2}$

$\text{Area of Mary's new garden}=2*64\text{ ft}^{2}$

$\text{Area of Mary's new garden}=128\text{ ft}^{2}$

Therefore, the area of Mary's new garden will be 128 square feet.

Find the least common denominator for the group of fractions.<br> 5/12, 9/14, 2/5, 1/10

makkiz [27]

9514 1404 393

Answer:

420

Step-by-step explanation:

The prime factors of each denominator are ...

12 = 2²×3

14 = 2×7

5 = 5

10 = 2×5

The unique factors are 2²×3×5×7 = 420.

The least common denominator of these fractions is 420.

_____

<em>Additional comment</em>

5/12 = 175/420
9/14 = 270/420
2/5 = 168/420
1/10 = 42/420
