Answer:

x=7

Step-by-step explanation:

The angles will always add up to 180.

Subtract 76 from 180, giving you 104

So now, your other two angles when added together equals 104.

104=5x+6+8x+7

Add your like terms, so add 5x and 8x to give you 13x, and add 6 and 7 to give you 13. Subtract 13 from both sides, leaving you with 91=13x

Divide 13 from both sides, giving you 7=x

Now plug in the 7 for the x for the original expressions. So 5x+6= 5×7+6

5×7=35+6=41

8x+7=8×7+7

8×7=56+7

56+7=63

Tickets to a concert cost $50 for each orchestra seat and $40 for each
Vsevolod [243]

Answer:

H. the number of orchestra seat is 900

Step-by-step explanation:

Step one:

let the number of orchestra seat be x

and balcony seat be y

cost of orchestra= $50 each

cost of balcony =$40 each

total tickets= 1500

x+y= 1500----------1

amount earned= $69000

50x+40y=69000--------2

The system of equation for the situation is

x+y= 1500----------1

50x+40y=69000--------2

from 1, x=1500-y

put this in equation 2

50(1500-y)+40y=69000

75000-50y+40y=69000

-10y=69000-75000

-10y=-6000

divide both sides by -10

y=-6000/-10

y=600

put y= 600 in equation 1

x+600= 1500

x=1500-600

x=900

X and Y are independent random variables. X is normally distributed with mean 1 and variance 1. Y is normally distributed with m
g100num [7]

Answer:

1

Step-by-step explanation:

Equation of variance:

Total Variance = sum (i=1, N) {c^2,variance^2}

= c1^2*variance1^2 + c2^2*variance2^2 + .....

Variance of X = 1

Variance of Y = 5

Variance of Y - 2X = (1^2)*(5) - (2^2)**(1)

= 5 - 4 = 1
