What is the full question, you cannot make an equation with only that
Do the problem little by little:
First, -20/48 reduces to -5/12.
Next, (t^5) / (t^7) simplifies to 1 / (t^2).
Same with u^2 / u^4: 1 / u^2
v^3 / v^1 = v^2
Let's put the factors back together:
-5 * v^2
--------------------------
12 * u^2 * t^2
-5 v
This could be left as is, or shortened: ----- * [ ------- ]^2
12 t*u
t = 3
Simple interest will be derived by multiplying the principal, the interest rate, and the term.
Interest = Principal x Rate x Term
Interest = 105
Principal = 700
Rate = 0.05
Term = ?
Based on the Simple Interest formula,
term = Interest / principal x rate
term = 105 / (700 x 0.05)
term = 105 / 35
term = 3
For an isosceles triangle angles ABC=ACB=35
Let the angle ADB be x
then ADC is 180-x
as AD is median so BD=CD
and for isosceles triangle AB=AC
so AB/AC=BD/CD=1
By angle bisector theorem
BAD=CAD=y (just take it)
for an triangle BAD 35+x+y=180...(1)
for an triangle DAC 35+180-x+y=180...(2)
35+y=x
therefore
35+34+y+y=180
2y+70=180
2y=100
y=55
therefore angle BAD=CAD=55
15 because one tie goes to each t shirt and 5-1 is 5 then you do it two more time’s because there are three shirts
