Answer:
one plus one is two the answer is 2
Angles that equal 180 degrees
Alright! When you have a constant to a power times another constant to a power (ex. [x^3 times x^3] ) you simply add the powers and keep the base [x^6]. When you have a power to a power (ex. [(12^3)^3] ) you multiply the powers and keep the base [12^9]. When you have a constant to a power divided by a constant to a power (ex. [ x^2 divided by x^5] ) you subtract the powers and keep the base. It's hard to see the questions, so I'll leave this here for you to use as a guide.
100-16=84
84÷7=12
there are 12 students in the class because first you subtract 16 from 100 so you have that left then you divide that by 7 to find out how many students get 7 markers.
