22=-11k is K= -2 hope this helps
Answer:
Step-by-step explanation:
Evaluate all the arithmetic first, and then remember absolute value equations have two possible ways to go (+ and -).
You can see how I split them on the 3rd line, later demonstrating how the 2nd one is invalid.
Therefore, the solution is
Complementary angles add to 90 degrees.
3x+5+2x-15=90
5x-10=90
5x=100
x=20 <=======
Plug in the value of x
3(20)+5
60+5
65= angle A <========
2(20)-15
40-15
25= angle B <========
Hello from MrBillDoesMath!
Answer:
One example is 52 and 54. They are between 50 and 60 and have the factor 2 in common
Discussion:
Consider the numbers between 50 and 60:
51, 52, 53, 54, 55, 56, 57, 58, 59
53 and 59 are primes so they don't have any factors in common and we can focus on the other numbers in the range.
Consider 52. It's even so is divisible by 2 as are 54, 56, 58. So 52 and 54 , for example, are are two number between 50 and 60 that have the factor 2 in common
Even number are visible by 2. Let's look for numbers visible by 3. How about 54 ( = 18 *3) and 57 ( = 19*3)? That works so its looks like there are many answers to this question.
Thank you,
MrB
The greatest place value is the tens spot which 2 is in the tens spot so we need to round up since 5 is next to the 2. The answer would be 30
