Answer: 12x-4, 14 counters, 8 more counters
Step-by-step explanation: There are 2x yellow, 4x+6 red, and 6x-10 blue counters. We need to add all of this up to get the total number of counters. We first add the x's : 2x+4x+6x = 12x. Then we add the numbers. 6+ (-10) is -4. So, our expression is 12x-4. Next, we need to find out how many blue counters are in the bag. We know that there are 44 total counters and we need to find x because all the counters have x in them. 12x-4 = 44. We first add 4 to both sides to get 12x= 48 and x = 4. blue has 6x-10 counters so, blue has 24-10 = 14 counters. Red has 16+6 = 22 counters. 22-14 = 8 more counters
11. 57% = 0.57
12. retail price = c + (0.57c)
13. retail price = 45 + (0.57 x 45)
retail price = 45 + 25.65
retail price = $70.65
14. 57% was added to the original price of the chain which is $25.65
Answer:
using implication
Step-by-step explanation:
let "if I go to college be (A)" and "I will get a better job be (B)"
therefore A implies B
(A ----------------> B)
If I go to college then I will get a better job.
This should be the correct answer 3x2(2x2+4)
Answer:
The number of minutes in a month must be equal to 50 minutes
Step-by-step explanation:
Let
x ---> the number of minutes
we have
<em>Cost Plan A</em>
<em>Cost Plan B</em>
we know that
In order for plan A cost the same than plan B, the following equation must hold true.
cost of plan A = cost of plan B
substitute
solve for x
therefore
The number of minutes in a month must be equal to 50 minutes
