A+8/3 = 2/3
Or, (3a+8)/3 = 2/3 [taking LCM]
Or, 3a+8 = 2 [3 in both denominators are cancelled]
Or, 3a = 2-8
Or, a = -6/3
.•. a = -2,,
Answer:
0.52
Step-by-step explanation:
(13/25)(4/4)=52/100
52/100=0.52
Answer:
x = 38.05
Step-by-step explanation:
Using the Pythagoras theorem to find x
x is the hypotenuse
The other sides are opposite and adjacent
x² = 30²+25²
x² = 900+625
x² = 1525
x = √1525
x = 39.05
Answer:
option A is the correct choice
Step-by-step explanation:
The trigonometric equation you are using has a general form
y = A* tan w*(x - r)
Where
A is the amplitude of the function
w is the frequency rad/s
r is the phase shift
In your case
A = 2
B = w = 3
r = pi/2
y = 2* tan 3*(x - pi/2)
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
