We have to use the Distributive Property in this equation.
By the Distributive Property,
becomes
Now we need to isolate x. Remember PEMDAS?
Simplify the right side.
Answer:
area is a half x l x h
Step-by-step explanation:
we cannot use the hypotenuse because it wouldn't bring the area
Answer: $62.25
Step-by-step explanation:
The mark-up is $477.25 - 415 = $62.25
Answer:
the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.
It is an advanced science class, therefore the students will most likely have a preference in science related careers, over representing science, and under representing anything else.
