Answer:
Antoinette's error
Option A) She distributed incorrectly.
Step-by-step explanation:
We are given the following information in the question:
Antoinette solves the linear equation

Antoinette made mistake in step 1 that is she did not distributed correctly.
If she would have distributed correctly, then she would have got the following solution:

Substituting x = -1 in the given equation, we gwt:

Antoinette's error
Option A) She distributed incorrectly.
Answer:
The pedals
Step-by-step explanation:
A tricycle requires 3 tires, 1 frame, and 2 pedals.
Divide all the amounts by the amounts needed for one tricycle.
270/3=90
90/1=90
170/2=85
The pedals can only be assembled onto 85 tricycles while everything else can be assembles into 90 tricycles.
Generally, x <span>• x is accepted to mean "x times x" or "x multiplied by x"
and x+x means "x plus x" or "x added to x"
let's try by subsituting numbers for them
if we can find one case where the statement "x+x is the same as x</span><span>•x" is false, then it is not true
let's try x=4
x+x=x</span><span>•x
4+4=4</span>•<span>4
8=16
false
so it is not true
(x+x is equal to 2x, so therefor if we were to solve 2x=x</span><span>•x, we would get that it is only true for x=2 and x=0)
it is not always true
