<em>P = a + b + c = 49 cm</em>
<em>a = b + 7 => b = a - 7</em>
<em>a = c - 5 => c = a + 5</em>
<em>_____________________</em>
<em>a + (a - 7) + (a + 5) = 49</em>
<em>3a = 49 + 7 - 5</em>
<em>3a = 51 </em>
<em>a = 17 cm</em>
<em>b = 17 - 7 = 10 cm</em>
<em>c = 17 + 5 = 22 cm</em>
Answer:
14
Step-by-step explanation:
4x-29+ 5x-9= 7x -10
4x+5x-29-9=7x-10
9x-38=7x-10
9x-7x=38-10
2x=28
x=28/2
x=14
Answer:
they will need to win 18/20 matches
Step-by-step explanation:
if winning 9/10 matches gives them a winning percentage of 90% then you take 9/10 and multiple it by 2 since they played two times the matches of 10, then you get 18/20
Answer:
Option 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
The function t, where t(x) = 9.50x represents the amount of money Fernando earns given the number of hours, x, that he works.
The domain of a function are the set of possible values of x, the independent variable that satisfies the function.
Fernando works between 12 and 25 hours each week. It means that the statement that best represents the domain of this function for any given week would be
12 ≤ x ≤ 25
