For the following linear equations, determine which inverse operation allows you to determine the solution of the equation. In y

VARVARA [1.3K]

Answer:

see explanation

Step-by-step explanation:

(1)

Given

$\frac{n}{5}$ = - 0.3

Since n is divided by 5 then use the inverse operation, multiplication.

Multiply both sides by 5 to clear the fraction

n = 5 × - 0.3 = - 1.5

(2)

Given

- 2n = 4 $\frac{1}{3}$ ← change to an improper fraction

- 2n = $\frac{13}{3}$

Since n is multiplied by - 2 then use the inverse operation, division.

Divide both sides by - 2

n = $\frac{13}{-6}$ = - $\frac{13}{6}$

Given: The circle below. Which is closest to the area of the shaded sector (the larger portion of the given circle)Round to the

Len [333]

ANSWER

$264in^2$

EXPLANATION

We have that the shaded sector is subtended at 210 degrees at the center of the circle that has a radius of 12 inches.

The area of a sector is given as:

$\frac{A}{360}\cdot\text{ }\pi r^2$

where A = angle the sector subtends at the circle's center

So, we have that:

$\begin{gathered} \frac{210}{360}\cdot\text{ }\pi\cdot12^2 \\ =263.89in^2 \\ \approx264in^2 \end{gathered}$

That is the answer.

Kevin and Randy Muise have a jar containing 62 coins, all of which are either quarters or nickels. The total value of the coins

KiRa [710]

Answer:

23 nickels, 39 quarters

Step-by-step explanation:

Let x = the number of quarters

Let y = the number of nickels

x + y = 62 x = 62 - y

.25x + .05y = 10.90

Multiply both sides of the equation by 100 to get rid of the decimal points.

25x + 5y = 1090

25(62-y) + 5y = 1090

1550 - 25y + 5y = 1090

1550 - 1550 - 25y + 5y = 1090 - 1550

-20y = -460

-20y / -20 = -460 / -20

y = 23 nickels

x = 62 - y

x = 62 - 23

x = 39 quarters
