If this the midpoint and st=x+3 and tu=4x-6 what is st and su

Mathematics
1 answer:
iragen [17]3 years ago
3 0

Answer:

st = 6

su = 12

Step-by-step explanation:

t is the midpoint of line segment su.

st = x + 3

tu = 4x - 6

Since, t is the midpoint of su, it should divide su into two equal parts. This means, measure of st and tu would be equal. So,

st = tu

x + 3 = 4x - 6

3 + 6 = 4x - x

9 = 3x

x = 3

st = x + 3 = 3 + 3 = 6

tu = 4x - 6 = 4(3) - 6 = 6

su = st + tu = 6 + 6 = 2(6) = 12

So, the measure of st would be 6 units and measure of su would be 12 units.

Sounds like:

3^2 + ---------- * (8).  This evaluates to 9 + 4 * 8 ), or 9+32, or 41.
                3

Note the importance of applying Order of Operations rules correctly here.
