Answer:
(y-1400)/4200 = x
Step-by-step explanation:
y=4,200x +1400
Subtract 1400 from each side
y-1400=4,200x +1400-1400
y - 1400 = 4200x
Divide each side by 4200
(y-1400)/4200 = 4200x/4200
(y-1400)/4200 = x
B:200 becuase "t" is the variable 10 multiplied by 8 day the days they want to plug into t so 80. 80+120 is 200.
Answer: 6
Step-by-step explanation: First, let's find the least common denominator between the 2 fractions, which is 4. Now let's multiply 9/2 by 2 to get the denominator of 4. Once you multiply the numerator and denominator by 2 you would get 18/4. So now the problem turns into how many 3/4 goes into 18/4. We know that 3/4 x 6 = 18/4. So the final answer is 6.
Hi there!
~
cosec 20 -cot 40= 1/sin 20 - cos 40/sin 40
= (sin 40 -cos 40 sin20)/(sin 40 sin 20)
= 1/sin 40 ( 2 cos 20 - cos 40)
=1/sin20 ( 2 cos(60-40)-cos 40)
=1/sin40( 2 cos 60 cos 40 - 2 sin 60 -sin 40-cos 40)
Put the value of cos 60
= 1/sin 40 ( 2 sin 60 sin 40)
=root(3)
Hope this helped you!
