Answer:

Katie is not cheating. From the question, it sounds like Katie's spinner is 1-12. James has two dice so he has two sets of each number 1-6. This means that Katie can roll two numbers greater than six but James can only roll up to six. Using probability, I think there is a 50% chance that Katie's number will be bigger than James every time she spins. A fairer way would be for them both to play with the same dice or spinner.

In a class of 30 students, there are four more girls than boys. a)Using x as the number of boys, write down an equation b)Solve
Aleksandr-060686 [28]

easy claps!!

Answer: 30=2x+4 and there are 17 girls in the class.

Step-by-step explanation: if x+4=[total girls] and x=[total boys] and 30=[total kids], then x+4+x = 2x+4 = [total kids], since total kids id 30 then our equation is 30 = 2x + 4 and x= 13boys so 30-13= 17girls.

It's BASIC prealgebra so you should probably practice bit more with linear equations!

The variables X, Y, and Z represent polynomials where X = a, Y = 3a – 5, and Z = a2 + 2. What is X2Y – Z in simplest form?
creativ13 [48]

Answer:

3a^3-6a^2-2

Step-by-step explanation:

Given

  • x=a
  • y=3a-5
  • z=a^2+2

We need to find the expression for x^2y-z in simplest form. Hence we plug in the substitutions into the expression and simplify:

x^2y-z\\=(a)^{2}(3a-5)-(a^2+2)\\=3a^3-5a^2-a^2-2\\=3a^3-6a^2-2

2nd answer choice is right.
