Izzie recently took a math test where each correct answer was worth 8.7 points. she also correctly answered a bonus question worth 13 points. if izzie score a 108.7 on the test, how many questions did she answer correctly? be sure to set up an equation before solving the problem

Let's use x as the number of questions she answered correctly. If we make an equation of out the question, it would be 8.7x+13=108.7 To solve the equation subtract 13 from both sides. So it will leave you with 8.7x=108.7-13, which is 8.7x=95.7. Divide both sides by 8.7, which will give you x=11. She answered 11 questions correctly.

Y=-3x is the correct answer

(m+11n)^2=(m+11n)(m+11n)=m^2+11mn+11mn+121n^2=m^2+22mn×121n^2 for example; use foil: (a+b)(a+b)first. a^2outside. abinside. ablast. b^2
