if x over 7 = 2 over 5, you set up a proportion. x should equal 14/5 or 2.8
1 and 2/5
2/5 + 3/7 = 14/35 + 15/35 = 29/35
2/5 + 3/7 = 14/35 + 15/35 = 29/35
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
If you add 2/7 to 5/7 it equals 7 which is one whole
If: x = 2/3 and x = 5/7 Then: (3x-2)(7x-5) = 0 Equation: 21x2-29x+10 = 0
2+5=7 5+2=7 2+5=5+2
To evaluate t-7 over w for t equals -3 and w equals -2, we substitute -3 for t and -2 for w in the expression. This gives us (-3) - 7 over (-2), which simplifies to -10 over -2. Further simplifying, we get 5 as the final result.
5-x equals 7 = -2
a/5 + a/2 = 14/2 2a/10 + 5a/10 = 7 7a/10 = 7 7a = 70 a = 10
Answer: x = 8/7
No, 7 - 2 = 5 (not -5)
