can someone help me with Lesson 9: Integers and Algebraic Expressions Unit Test for connection academy help plz
if this gets 15 likes ill post the answers all ill tell you so far is 1~is D
So we all on connexus nice
can someone please help us with this 24 question unit test
can someone post all the answers to lesson 9 it has 24 questions plz
please help us theres 24 questions its lesson 9 for 8th grade math

And Rex I feel like you just said the "abcd" answers in random order
i can help anyone who wants it on 23 and 2
Well I have these up until 7
So
2: -55+q=7? Is -42
3: the addItive inverse of 22 is -22
4: the solution to y + 7 = -9 is -2
5: the values of -3 • (7+(-3)^2)÷3? Is -16
Sorry I don't have the rest right now 🤷♀️
someone plz post correct answers
idk if rex is right bc on 4 it cant be b it is a i think
so who is right
natasha did u finish the test if u did can u help me plz

can some one tell me what to say for the audio recording one
yeah ‘:)’ has different questions, we’re all here for the answers but answers to different questions yikes
Explain the difference in meaning between |-3| and -3
Thanks for the tips I d 0 t s
bruh how hard is it to post the right answers
I eat Chit-tea is right use her
Please help me I really need the answers
idk is wrong i got 5/22

C -3 less than 1
D 6 less than -12
Where our answers bruh got 23 likes and he aid 'i need 15'
OKAY anonymous the diff of l-3l and 3 is nothing the ll turns it to the absolute value
Hopes that helps!!!
OMG sorry read that wrong the difference is l-3l is 3 and -3 stays the same.
SO SO SORRY IGNORE THE FIRST ONE!
Finishing up my test now I’ll give the answers hope I’m not too late
Nvm wrong test lol
Wished I could help you but, I don't have the answers too. :) I'm sorry to tell you that.
Vocabulary Check: Define the following terms and provide examples (if it applies). This should be completed prior to attending the review livelesson.
∙ Absolute Value- the absolute value of a real number x, denoted |x|, is the non-negative value of x without regard to its sign. Namely, |x| = x if x is positive, and |x| = −x if x is negative, and |0| = 0.
∙ Additive Inverse- additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.
∙ Distributive Property- the distributive property of binary operations generalizes the distributive law from elementary algebra, which asserts that one has always
∙ Equation- equation is a statement that asserts the equality of two expressions, which are connected by the equals sign =
∙ Inverse Operations- Inverse operations are pairs of mathematical manipulations in which one operation undoes the action of the other—for example, addition and subtraction, multiplication and division. The inverse of a number usually means its reciprocal, i.e. x - 1 = 1 / x . The product of a number and its inverse (reciprocal) equals 1
∙ Isolate- Using inverse operations to undo addition, subtraction, multiplication, and division to get the variable alone
∙ Order of Operations- the order of operations is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression
∙ Variable a variable is a symbol which works as a placeholder for expression or quantities that may vary or change; is often used to represent the argument of a function or an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions
Simplify the expression. Make sure to include various key words you learned in this unit. Clearly list the steps in order so that anyone reading this can follow. Make sure to circle or highlight the simplified solution:

If these are wrong for ur test then that means the teachers mixed up the test but I got 15/30 from using Rex and these are all the right answers
Anonymous is completely wrong and does not know what he is talking about. The real answers should be done by yourself for the best learning experience and best credit
All you people up in here cheating...no just no✋ by the way anyone who tries to say the answers are correct they're not, I promise you. Just do the work and hope for the best!
