So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.
Answer:
7x-9
Step-by-step explanation:
Substitue into one equation.
(f) - (g)
(4x-7) - (-3x+2)
Distribute negative through g(x)
(4x-7) + 3x-2
Simplify
4x-7 + 3x-2
7x-7-2
7x-9
Answer:
x = 6
Step-by-step explanation:
We solve that above question using the trigonometric function of Tangent
Tan theta = Opposite/Adjacent
Theta = 45°
Opposite = 6
Adjacent = x
tan 45° = 6/x
tan 45 in rational form = 1
1 = 6/x
Cross Multiply
x = 6
