Answer:
9)x=11 y=3
11)x=18 y=5
Step-by-step explanation:
9) 9x+25=13x+19 13x-19+17y+5=180
9x+44=13x 129+17y=180
44=4x 17y=51
11=x y=3
11) 49+3x=7x-23 3x=11y-1
Answer:
The answer is 2 1/2
Step-by-step explanation:
First you turn 3 3/4 into an improper fraction .To do that you multiply the denominator x the whole number + the numerator = 4x3=12 +3=15/4.
Then you turn 1 1/2 into an improper fraction .To do that you multiply the denominator x the whole number + the numerator =2x1+1=3/2
15/4 divided by 3/2 but get your answer you have to reverse 3/2 into 2/3 and you multiply instead of dividing .
15/4 x 2/3 =15 x2 = 30 , 4x3=12 so your answer will be 30/12 but it can be simplified because they are both multiple of 6 . So , 30 divided by 6 = 5 and 12 divided by 6 = 2 so then you answer is 5/2 but it is an improper fraction so you divide 5 by 2 and you get 2 and a remainder of 1/2=2 1/2

<h3><em>The </em><em>answer </em><em>is </em><em>option </em><em>a </em><em>.</em><em> </em><em>6</em><em>.</em><em>1</em></h3><h3 />
Since the answer is in fraction form, you know to divide.
So, -24/7=
-3.42857143
If you want it in rounded form, its:
-3.42
So the answer is either: -3.42857143 or -3.42
Hope this helps, have a good day. c;
Sorry as a mixed number its -3 and 3/7
