They can get at least 25% of the student population to sign a petition. So far, 82 students have signed the petition, Jose used the following steps to write an inequality that can be used to determine the number of student signatures
still needed:
Step 1. Declare the variable: Let x = the number of student signatures still needed.
total number of signatures needed X+82
Step 2. Create a ratio equivalent to total number of students in the school 426
Step 3. Convert 25% to a decimal: 25% = 0.25.
X+82
Step 4. Write the inequality: 426
30.25
What is Jose's error?

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,

answer: what equations are there

step-by-step explanation:

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
