Answer:
B
Step-by-step explanation:
X: 90 degrees. y: 43 degrees
We know that x is a right angle. The way we find y is to add 47 + 90 which gives us 137. We also know that a right triangle adds up to 180. So, we subtract 137 from 180. This means that y would be 43 degrees.
You have to move the -2/5 by the 11j to get k by its self
K=11j+-2/5

How to write numbers in standard form:
Write the first number 8.
Add a decimal point after it: 8.
Now count the number of digits after 8. There are 13 digits.
So, in standard form: 81 900 000 000 000 is 8.19 × 10¹³
Answer: 36
Explanation:
• group like terms
—> 3/4m + -2/3m = 5 + -2
•find lowest common denominator
—> 3/4*3 m + -2/3*4m= 5 + -2
•multiply denominator
—> 3/12m + -2/12m = 5 + -2
•combine like terms
—> 1/12m = 3
•simplify the arithmetic
—> m= 3 over 1/12
—> m= 36
