Extend Question #28
Hey 9-05! We were all assigned a question which we're supposed to make a post and explain how to solve the question. Well I was assigned #28. Red=question and Orange=Value of Variable
Evaluate the following:
a) 3.6 + 2y, y= -0.5Evaluate the following:
1) They tell you the value of the variable so, you must fill that in (y= -0.5)2) Follow PEDMAS: First multiply 2 with -0.5
3) A positive + a negative sign side by side = a negative sign
4) Add the addends together and recieve the sum
(m - 1.8) (m + 1.8), m=1.7
1) Fill in the values of the variables.
2) Answer the questions in the brackets
3) Multiply the answers from each bracket together
4) Recieve the answer.
4.5/q - q/4.5, q=-3.6
1) Fill in the Variables
2) To add/subtract fractions, they must have a Common Denominator. To create a common denominator. Simply add one the fraction by a an eqiuivalent fraction of 1. (eg. -1.25/-1.25) Now both of the denominators in every fraction is 4.5 .
3) Subtract the numerator by numerator. Yet don't do anything to the denominator.
4) You have your answer. If asked, reduce it to lowest terms.
Hey Joseph, nice post it really helped me understand this question better. And if you can make the division sign by pressing alt 2-4-6, like this ÷ :)
ReplyDeleteNIce post JOseph and I really like the pictures. You made a couple spelling errors(pedmas) but nice post though=)
ReplyDeleteHI JOSEPH! Great job on your post, I agree with Francis, there are a couple of spelling mistakes, such as "recieve", I think its supposed to be spelt "receive" but, I don't know I could be wrong. But, pedmas.. hm. You said PEDMAS because of parenthesis right? Because if thats the case, I'm pretty sure its right. Anyways, good job (;
