Let's start with number 2. To do this you have to transfer it into an equation. Know that in this type of situation, you can turn the word "is" into an equals sign. Next, break it up. 7 times the sum of a number and six. That is the first part. First, find an expression for both. 7 is just 7. And now, a number and 6. You can always substitute "a number" with x. So a number and 6 would be x+6. 7 times the sum of a number and 6 would be... 7*(x+6). Now lets get to the other side of the equation. This is easy. "negative 43" would be -43. So the final equation would be. 7(x+6)=-43

Anton [14]

Answer:

$\$400$

Step-by-step explanation:

GIVEN: A hotel charges a $\$10000$ annual fee plus an additional $\$200$ for each night you stay there.

TO FIND: average cost per night if you stay at the hotel for $50$ nights.

SOLUTION:

Annual fee charged by hotel $=\$10000$

amount charged each night we stay there $=\$200$

Total number of nights we stay $=50$

Total amount paid for $50$ nights $=50\times\$200$

$=\$10000$

Total amount paid $=\text{annual fee}+\text{total amount paid for 50 nights}$

$=\$10000+\$10000$

$=\$20000$

average cost per night $=\frac{\text{total amount paid}}{\text{total number of nights of stay}}$

putting values,

average cost per night $=\frac{20000}{50}$

$=\$400$

Hence average cost per night if we stay at hotel for $50$ days is $\$400$

I need help solving this problem.

madam [21]

(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)

2x^2 + 3x + 4x - 9 = 2x^2 +7x -9

2x^2 + 7x - 9 - x^2 -7x = x^2 -9

The answer is : x^2 - 9
