Answer:
54
Step-by-step explanation:
Answer:
∠A = 90
∠B = 30
∠C = 60
Step-by-step explanation:
Let ∠B = x
∠A = 3x
∠C = x + 30
Angle sum property of triangle: Sum of three angles of triangle is 180
x + 3x + x + 30 = 180 {Combine like terms}
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 130/5
x = 30
∠A = 3*30 = 90
∠C = 30 + 30 = 60
Answer:
(2x+7t) (5x-3p)
Step-by-step explanation:
Step-by-step explanation:
The equation 0.5s+ 9.99=30 describes the situation.
9.99 is the fixed amount
0.5 is the cost for each song download
30 is the maximum amount spend for a month
Here 's' represents the number of songs download
0.5s+ 9.99=30 means
0.5 times the number of songs plus the fixed cost 9.99 should be equal to 30 dollars.
The solution to this equation is s=40.02.
s= 40.02 means 40 songs can be downloaded as per the budget
