C because i just took de test
4 legged tables : x
3 legged stools : y
x + y = 20 y= 20 - x
4x + 3y = 68
Replace y by 20 - x so we only have one letter
4x + 3(20 - x) =68
4x + 60 - 3x =68
x + 60 = 68
x = 8
To find y replace x by 8
y = 20 - 8
y = 12
So you have 8 four legged chairs and 12 three legged stools.
Hope I helped!
Step-by-step explanation:
180-89=91(angles on a straight lline)
5x-24=91(Corresponding angles)
5x =91+24
5x =115
<em> x =23 degrees</em>
94+13x-5=180(allied angles)
94+13x-5 =180-94+5
13x =91
<em> x=7</em>
7(x-7)=7x-49
7x-49=126(corresponding angles)
7x =126+49
7x=175
<em> x=25</em>
