Answer:
100-mn
Step-by-step explanation:
He bought m books for n dollars each to know the amount of the books he bought,it means m×n=mn
He had $100 intially so to determine the amount left
100-the amount spent
100-mn
Therefore the answer is 100-mn
Answer:
2pi
Step-by-step explanation:
Subtract 9 twice.
24-9-9 = 6
Half of 6 is 3, so 3 is the width since adding it twice and adding the length twice gives perimeter.
Answer:
D) would be the answer
Step-by-step explanation:
Domain is always the set of x-coordinates in the pairs and the range is always the set of y-coordinates in the pairs.
D: 7, -2, 4, -9, 0
R: 3, -2, 1, 0, 7
Put them in order from least to greatest.
D: -9, -2, 0, 4, 7
R: -2, 0, 1, 3, 7
So here is what you would do:
lets just pretend that there is no x in the equation
so this is what the equation would look like:
first, is 4 to the power of 2=16 and now we are going to put the x back into the equation so: 4x to the power of 2, but we did the exponents so, now x is the missing number. We can use the 32 because it is the solution to the equation. So we would do 32-16=16 so the missing number is 16 so x=16
Answer: x=16
