⓵ You need to solve the left side first in order to isolate the × and find it’s value :

-7× + 6 = 27
-6 -6
↓

-7× = 21
÷-7 ÷-7

↓

× = -3

If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!


I hope this helped, if there’s anything let me know! ☻

a scale drawing of a bus has a scale of 1/2 inch to 5 feet. If the length of the school bus is 4 1/2 inches on the scale drawing
TEA [102]

Let x feet be the actual length of the school bus. You know that in a scale drawing

\dfrac{1}{2} \text{ inch } - 5 \text{ feet},

then

4\dfrac{1}{2} \text{ inch } - x \text{ feet}.

Write a proportion:

\dfrac{\frac{1}{2}}{4\frac{1}{2}}=\dfrac{5}{x}\Rightarrow x=\dfrac{5\cdot 4\frac{1}{2}}{\frac{1}{2}}=\dfrac{5\cdot \frac{9}{2}}{\frac{1}{2}}=\dfrac{\frac{45}{2}}{\frac{1}{2}}=\dfrac{45}{2}\cdot \dfrac{2}{1}=45\text{ feet.}

Answer: the actual length of the school bus is 45 feet.

The correct answer  for the problem shown in the figure atttached is the last option (option D), which is shown below:

 D.(-x-9i)(x-9i)

 If you want to verify that the option D.(-x-9i)(x-9i) is the correct answer, you can apply the distributive property to (-x-9i)(x-9i).

 Therefore, when you apply the distributive property, you obtain that the result is:

 -x²-81

 The graph attached shown this equation, which is a parabola.
