20 cards replaced and now have 37
37-20=17
17 is half of the baseball cards
17x2= 34 which is what you began with
Answer:
Step-by-step explanation:
Complementary angles add up to 90
6x + 29 + x + 5 = 90
6x + x + 29 + 5 = 90
7x + 34 = 90
7x = 90 - 34 {Subtract 34 from both sides}
7x = 56
x = 56/6 {Divide both sides by 6}
x = 8
∠A = 6x + 29
= 6*8 + 29
= 48 + 29
∠A = 77°
Well, if you take x to be 25 seconds, there are 2.4x in 1min. So, that multiplied by 60, would be 144x. Therefore, 1/4 multiplied by 144x should be the answer.
Answer:
Let n and n+4 be the numbers. Then:
n² + 3(n+4)=66
n²+3n-54=0
(n+9)(n-6)=0
n=6 or -9
n+4=10
Assuming positive integers only, the numbers are 6 and 10…..
