The only thing I'm a little unclear on here is what you mean by
the "legs" of an isosceles triangle.
I'm going to assume that your isosceles triangle is standing on
the side you call the "base", and the "legs" are the two slanty ones,
standing up, which are the two equal sides.
With that set-up, x + 1 = -x + 7
Add x to each side: 2x + 1 = 7
Subtract 1 from each side: 2x = 6
Divide each side by 2 : x = 3
Finally, if the base is (3x - 3), then that's (3·3 - 3) = 6 .
Answer:
They have opposite signs. if x=16 then y should be -16 for their sum to be zero.
9 / 15
9 / 3 = 3
15 / 3 = 5
so 3 / 5
60/100
6/10
Answer:
$0.86, or 86 cents
Step-by-step explanation:
5 = $ 4.30
1 = $ 0.86
$4.30/5 = $0.86, or 86 cents per pound.
Answer: The statement is true.
Explanation: AB is approximately equal to DE. BC is equal to EF and angle ACB is approximately equal to angle DEF, therefore triangle ABC is approximately equal to triangle DEF.
Hope this helps :)
