Let's simplify them top to bottom.
6(x + 2) < x - 3
6x + 12 < x - 3
5x + 12 < -3
5x < -15
x < -3
This one checks out.
3 + 4x <= 2(1 + 2x)
4x + 3 <= 4x + 2
This is a problem. In no world is 4x + 3 ever less than or equal to 4x + 2. This one has no solution.
Step 1: Cross-multiply.
(x+3)^1/2=(3x+7)^1/4
Step 2: Subtract 6x from both sides.
4x+12−6x=6x+14−6x
−2x+12=14
Step 3: Subtract 12 from both sides.
−2x+12−12=14−12
−2x=2
Step 4: Divide both sides by -2.
−2x/−2=2/−2
Answer:
x=−1
72,000 + 47,500 + 65,000 +(3 X 10,000)=214,500 Total costs and expenses of the stadium
482,000 - 214,500=$267,500. Hope I helped :)
since alie ate 15 gram and there are 12 grams in every 8.
what i did, I made a table that looks like
once you make a table that looks like this, in this kind of situations.
multiply across ( yellow ones)
and then divide by the green one
and then you'll get the answer
