Appropriate units to measure the width of a house would be meters in metric and feet in English
4. 5/6x3/5=15/30=1/2, 4/8 simplified would be 1/2 so they're the same. 6. 4/9x7/8= 28/72=7/18, 8/18x21/24= 1/6x7/3=7/18 so they're the same. :) I hope this helps
Answer:
y=3 x= -5/2
Step-by-step explanation:
simultaneous equations
2x + 4y = 7 ------ eq 1
-2x + 3y = 14 --------eq2
(different signs add)
(eq 2 + eq 1)
-2x +(-2x) = 0
4y+3y = 7y
7+14 = 21
7y= 21
(divide both sides by 7)
y= 21/7= 3
2x + 4(3) = 7
2x+ 12=7
2x = 7-12
2x = -5
x= -5/2
