Answer:
the answer is there should be another digit in the quotient
1/3x + 3/5 * 2/3x = x - 36
1/3x + 6/15x = x - 36
11/15x = x - 36
4/15x = 36
x = 135
sweater costs 1/3x = 45
hope that helps, God bless!
All of the statements has the qualifier "can be".
This means that we need just one single in each example to make the statement true.
In an equilateral triangle, medians, angle bisectors, altitudes and perpendicular bisectors are all coincident, which makes the first three statements true. This in turn makes the fourth statement true.
So there are no false statements.
For 3 find the total area for the big semicircle, then find the area of the smaller one and subtract it. It would be the same for 4 but instead you find the total area of the square (24 x 24) and then subtract the semicircle are. (you were wrong on #4)
