In a recent year, person A and person B had the two top-grossing concert tours, together generating about $300 million in ticket

Brrunno [24]

Answer: Person B had $114,000,000 and person A had $186,000,000

Step-by-step explanation:

You do $300 million divided by 2 to get 150,000,00 and then subtract 150,000,000 - 38,000,000= 114,000,000 and that's for person B and than you add the 38,000,000 to the 150,000,000 to get the amount person A had.

There you go!!!

Solve by adding or subtracting.<br> x+y=-10<br> 2x-y=-8

riadik2000 [5.3K]

Answer:

$x=-6\\y=-4$

Step-by-step explanation:

To solve, isolate your first equation for y.

$x+y=-10\\y=-x-10$

Now, plug in this y value to your second equation.

$2x-(-x-10)=-8\\2x+x+10=-8\\3x+10=-8\\3x=-18\\x=-6$

Now, plug your x value into your first equation and solve for y.

$-6+y=-10\\y=-4$

One hose can fill a goldfish pond in 36 minutes, and two hoses can fill the same pond in 20 minutes. Find how long it takes the

rjkz [21]

Answer:

45 minutes

Step-by-step explanation:

It is given that one hose can fill a goldfish pond in 36 minute

So the the first hose can fill goldfish pond $\frac{1}{36}$ per minute

When both fill together then they fill in 20 minutes

So the the both hose can fill goldfish pond $\frac{1}{20}$ per minute

Let Goldfish pond filled by second hose $\frac{1}{x}$ per minute

so $\frac{1}{36}+\frac{1}{x}=\frac{1}{20}$

$\frac{1}{x}=\frac{1}{20}-\frac{1}{36}$

x=45 minutes

one interior angle of a polygon is equal to 800 and each of the other interior angles are 128 degrees. Find the number of sides

KiRa [710]

Answer:

Step-by-step explanation:

Given information:

Interior angle of a polygon cannot be more that 180°.

One interior angle = $80^{\circ}$

Other interior angles are = $128^{\circ}$

Let n be the number of sides of the polygon.

Sum of interior angles is

$Sum=80+128(n-1)$

$Sum=80+128n-128$

Combine like terms.

$Sum=128n-48$ .... (1)

If a polygon have n sides then the sum of interior angles is

$Sum=(n-2)180$

$Sum=180n-360$ .... (2)

Equating (1) and (2) we get

$180n-360=128n-48$

Isolate variable terms.

$180n-128n=360-48$

$52n=312$

Divide both sides by 52.

$n=\frac{312}{52}$

$n=6$

Therefore the number of sides of the polygon is 6.
