The correct answer is A. Subtract c from both sides of the inequality and you’re left with 8 > 4. That’s always true! from Tumblr https://ift.tt/2Oa6SYI
Rearrange that equation: x + 2y = y x = –y x/y = –1 from Tumblr https://ift.tt/2EP6ejY
Best way to go if you’re not sure is to solve for n. Now all you need to do is find 5/7 of 98. Another way to go is to recognize that if the denominator of 7 is common to both fractions, all you really need to do is divide by 3 and multiply by (more…)

For question 13 test 1 no calculator, I used plugging in. I made x = 4 and solved to get 42/13. then I plugged 4 into my answer choices and B gave me 42/13.
I am curious as to why you did not use plug in for your answer and explanation.
Test 3 Section 4 #30
(4x + 4)(ax – 1) – x^2 + 4
In the expression above, a is a constant. If the expression is equivalent to bx, where b is a constant, what is the value of b?
No idea how to solve this! I tried factoring this way and that, expanding, setting everthing on left in form of x (….) + 4 = bx, but no go. Help!
