10-x=3x-4 = 3.5
Answer: 3.5
Answer:
7/12
Step-by-step explanation:
Find the common denominator 24 so fraction would change to 6/24 + 8/24
that equals 14/24 and simplified that 7/12
The midsegment is half the length of the base.
1) 32 ÷ 2 = 16
<em>So</em><em>,</em><em> 16 is the midsegment</em>
2) 11 ÷ 2 = 5.5
<em>So, 5.5 is the midsegment</em>
3) 32 ÷ 2 = 16
<em>So</em><em>,</em><em> 16 is the midsegment</em>
<em>4</em><em>)</em><em> </em>14 ÷ 2 = 7
<em>S</em><em>o</em><em>,</em><em> </em><em>7</em><em> </em><em>i</em><em>s</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>m</em><em>i</em><em>d</em><em>s</em><em>e</em><em>g</em><em>m</em><em>e</em><em>n</em><em>t</em>
Answer:
x=-1, y=3
Step-by-step explanation:
3x+2y=3
3x-2y=-9
since we have -2y and 2y we can just add the equations
6x=-6
x+0y=-1
x=-1
to solve x using elimination multiply the top equation by -1
-3x-2y= -3
3x-2y=-9
and add
0x-4y=-12
-4y=-12
y=3
and substitute x and y to double; check
3(-1)+2(3)=3
-3+6=3
3=3
checks out so these are correct
