A videographer earns $485 for every wedding he records and $18 for every extra copy of the video his costumers order . How much
kupik [55]
All you have to do is start by multiplying 485 and 34 (485*34) to find how much he made by just weddings. That should be equal to 16,490. Then you have to multiply 18 by 87 because he charged 18 per copy and there was 87 copies so (18*87). This should now be equal to 1,566. Since you want the total you now should add them which should be 16,490+1,566 and that is equal to 18,056.

Solve the equation 5(x+2)=6x+3x-14
Lapatulllka [165]

Answer: x = 6

Step-by-step explanation:

First step is to distribute the 5(x + 2).

5x + 10 = 6x + 3x - 14

The 6x and the 3x on the right can be combined.

5x + 10 = 9x - 14

Now add 14 to both sides to isolate the 9x.

5x + 24 = 9x

Subtract 5x from both sides.

24 = 4x

Divide by 4 to get x by itself.

6 = x

Please help me with this problem. (7+-12)*9. Thanks
MrRissso [65]

Answer: -45

Step-by-step explanation: According the order of operations, or PEMDAS, we first simplify what's inside the parentheses.

So here, we have 7 + -12 which is -5.

When we are adding a negative, think of it as subtracting a positive so 7 + -12 can be changed to 7 - 12 or -5.

Now, we have (-5) (9).

Since a negative multiplied by a positive gives us a negative, -5 multiplied by 9 will give us an answer of -45.

Therefore, (7 + 12) × 9 = -45.
