Answer: 48
Step-by-step explanation: just got it right on ap3x
3/2x-4=20
We simplify the equation to the form, which is simple to understand
3/2x-4=20
We move all terms containing x to the left and all other terms to the right.
+2x=+20+4
We simplify left and right side of the equation.
+2x=+24
We divide both sides of the equation by 2 to get x.
x=12
Answer:
45 cm^2
Step-by-step explanation:
The formula you have written in pencil is correct.
Area = B*H
B = 9
H = 5
Area = 5*9
Area = 45 cm^2
Answer:
64 weeks
Step-by-step explanation:
Given that you already have $400 saved and you save $50 per week, in x weeks, you would have saved:
400 + (50 * x)
Also, given that Mr Brierley has $2000 in his bank account and he saves $25 per week, in x weeks, he would have:
2000 + (25 * x)
You and Mr Brierley would have the same amount of money when:
400 + (50 * x) = 2000 + (25 * x)
Solving for number of weeks, x, we have:
400 + 50x = 2000 + 25x
Collecting like terms:
50x - 25x = 2000 - 400
25x = 1600
x = 1600 / 25
x = 64
Hence, it will take 64 weeks for you and Mr Brierley to have the same amount of money.
This is what I got - csc pi/2 - 1 ( on 29 ) and cot pi/4+1 ( on 27 )
