Answer:
-9x^9y^5
Step-by-step explanation:
Do the multiply first:
-16x^9y^5+7x^9y^5

Answer:
original price =148.57
Step-by-step explanation:
The original price * discount is the markdown
original price - discount = sale price
original price - original price * discount = sale price
Factor out the original price
original price (1-discount) = sale price
We know the discount is 65% and the sale price is 52
original price (1-.65) = 52
original price (.35) = 52
Divide by .35 on each side
original price (.35)/.35 = 52/.35
original price =148.57
Answer:
1.61 * 10 ^8
3.3 * 10^-7
Step-by-step explanation:
Multiply the numbers and then add the exponents
2.3 * 10^1 * 7 * 10^6
2.3 *7 * 10^(1+6)
16.1 * 10^7
We need to make this scientific notation by moving the decimal one place to the left and adding 1 to the exponent
1.61 * 10 ^8
Multiply the numbers and then add the exponents
1.1* 10^-5 3*10^-2
1.1 *3 * 10^(-5+-2)
3.3 * 10^-7
There really is no way of telling. If the 51 got 100, then the rest could have gotten anything. If there is no graph, or data, or anything else to support the question, that means the 27 could have gotten any mark.
