Answer:

The actual locomotive is 76 ft long.

Step-by-step explanation: Multiply 10.4712 by 87 to get the number of inches. Then divide by 12 to convert inches to feet.

a tank is 1/6 full of gasoline. If 8 litres are added it would be 1/4 full. how many litres does the tank hold?
shtirl [24]
Find a common denominator between the two

1/6 - 2/12
1/4 - 3/12

3/12 - 2/12 because 2/12 is what you started with

= 1/12

If 1/12 is 8 litres, it’s 8 x 12 = 96

The tank can hold 96 litres.

The drama club is selling tickets for a play. The profit, y, is
Goshia [24]

Answer:

80 tickets

Step-by-step explanation:

Given the profit, y, modeled by the equation, y = x^2 – 40x – 3,200, where x is the number of tickets sold, we are to find the total number of  tickets, x, that need to be sold for the drama club to break  even. To do that we will simply substitute y = 0 into the given the equation and calculate the value of x;

y = x^2 – 40x – 3,200,

0 = x^2 – 40x – 3,200,

x^2 – 40x – 3,200 = 0

x^2 – 80x  + 40x – 3,200 = 0

x(x-80)+40(x-80) = 0

(x+40)(x-80) = 0

x = -40 and x = 80

x cannot be negative

Hence the total number of  tickets, x, that need to be sold for the drama club to break  even is 80 tickets

Given: T is the midpoint of JK¯¯¯¯¯JK¯, JK = 5x – 3, and JT = 2x + 1. Determine the length of JK¯¯¯¯¯JK¯
Helen [10]
JK where T is the midpoint.   J >>>>> T >>>>> K. 

JK = 5x - 3
JT = 2x + 1

Because T is the midpoint, it means that  JT = TK
So, JT + TK = JK

(2x + 1) + (2x + 1) = 5x - 3
4x + 2 = 5x - 3
4x - 5x = -3 - 2
-x = -5
x = 5

JK = 5x - 3
JK = 5(5) - 3
JK = 25 -3
JK = 22

The length of JK is 22.

eduard

Answer:

the answer is 2

Step-by-step explanation:

add -4x and -6x and the answer is -10x bc they are both negative x. then divide both -10x and -20 by -10 so that it is x by itself on one side and 2 on the other so its 2=x :)
