42.5units^2
Step-by-step explanation:
Area of a trapezium=1/2 *(a+b) height.
a=5 units
b=12units
height=5units
Area=1/2*(5+12)*5
Area=1/2*17*5
Area=1/2*85
Area=42.5units^2
Answer:
The student took 28 classes
Step-by-step explanation:
What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.
This means that it is 8x-28=15+x. We let x equal the number. You can solve for the equation.
