Answer:
It takes 13 months for the second phone to be less expensive than the first phone.
Step-by-step explanation:
First phone: y = 100 + 55x
Second phone: y = 150 + 51x
(x = number of months, y = total cost)
Make a T-Chart.
First phone: Second phone:
<u> x | y </u> <u> x | y </u>
0 | 100 0 | 150
1 | 155 1 | 201
2 | 210 2 | 252
3 | 265 3 | 303
4 | 320 4 | 354
5 | 375 5 | 405
6 | 430 6 | 456
7 | 485 7 | 507
9 | 595 9 | 609
10 | 650 10 | 660
11 | 705 11 | 711
12 | 760 12 | 762
13 | 815 13 | 813
After 13 months, the second phone will have costed $2 less than the first phone, and the price of the second will continue to be lower than the first.
This question more or less tries to trick you with the positive number in parentheses, as you would carry out subtraction as normal. However, since the number you are subtracting from is also negative, it would be easier to think about it as adding two positives, and setting aside the negative symbol for the answer.
-282 - 1017 = -(282 + 1017) = -(1299) = -1299
which is your final answer.
-282 - (+1017) = -1299.
Hope that helped! =)
No idea I don't know the answer
If it were a complete circle, its circumference would be
(π) x (diameter) = (π) x (2R) = 70 π inches .
Since it's only half of the circle, the length of the curved part is
70 π / 2 = 35 π = <em>109.9 inches</em> .
The value of the given task 0.8 million - 1.76 thousand is 798,240.
<h3>Place value</h3>
0.8 million
= 0.8 × 1,000,000
= 800,000
1.76 thousand
= 1.76 × 1000
= 1,760
So,
0.8 million - 1.76 thousand
= 800,000 - 1,760
= 798,240
Therefore, 0.8 million - 1.76 thousand is 798,240
