Answer:
5.76 yards (144/25)
17.3 foots (173 / 10)
Step-by-step explanation:
Answer:
f(a) = 1,5
Step-by-step explanation:
-3a + 6b = a + 4b
[+3a] [+3a]
6b = 3a + 4b
[-4b] [-4b]
2b = 3a
[÷2] [÷2]
b = 1,5a
Answer:
A= 4x-4
4x-4 since you have 3x-1 on the bottom and x+1 on the side. Thus, you replace the x from x+1 with 3. From there, you get 4.
Answer:
4 × 3 - 2 × 5 = 12 - 10 = 2
2x² + 3y² = 2 × 9 + 3 × 25 = 18 + 75 = 93
x = 73.21
Step-by-step explanation:
Consider triangle ABC. Since angle A is 45° and side BC is 100, then side AB is also 100.
Now consider triangle ABD. With angle A equal to 60°, we can use the definition of tangent to find the value of x:
tan 60 = BD/AB
sqrt(3) = (x + 100)/100
or
x + 100 = 100sqrt(3)
x = 100[sqrt(3) - 1]
= 73.21
