Xio just took a math test with 25 questions, each worth an equal number of points. the test is worth 100 points total. if a score of 83 points earns a grade of b, how many questions would xio need to get right to get a b on the test?

So, Xio wants a B for his math test.

Well, each question is worth 4 points

You divide 83 by 4 which will equal 20.75. (Round up)

If he wants the B for his math test, Xio will need to get 21 questions correct.

Hope I helped!

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
