Answer:

Step-by-step explanation:

2(3x−5)+4x−10=4x+2(x+6)

Step 1: Simplify both sides of the equation.

2(3x−5)+4x−10=4x+2(x+6)

(2)(3x)+(2)(−5)+4x+−10=4x+(2)(x)+(2)(6)(Distribute)

6x+−10+4x+−10=4x+2x+12

(6x+4x)+(−10+−10)=(4x+2x)+(12)(Combine Like Terms)

10x+−20=6x+12

10x−20=6x+12

Step 2: Subtract 6x from both sides.

10x−20−6x=6x+12−6x

4x−20=12

Step 3: Add 20 to both sides.

4x−20+20=12+20

4x=32

Step 4: Divide both sides by 4.

4x/4 =32/4

x=8

Please help with these two math questions!!!
Aleksandr [31]

Answer:

&

Step-by-step explanation:

12.) If one ticket is $9.50, and 879,575 tickets were sold, the two need to be multiplied. 9.5 * 879,575 = 8355962.50

So the total profit was $8,355,962.50

If each theater made an equal profit of that total, then just divide it by 755, but if that's not the case, then don't do that.

13.) If the boat can carry 582 passengers, and 13,105 people had ridden the first boat, then you have to divide the number of people riding the boat by the passenger count to determine the amount of trips made.

13,105 / 582 is 22.5, but you can round it to 23, because half of a trip isn't going to be made. I'm not entirely sure when the second question means, so... sorry, can't answer that one.

Hope this helps somewhat!
