L=5+2w would be the best answer
Sin+cos=90
49+cos=90
cos=41
Answer:
Step-by-step explanation:
it's simple my dear friend.
first, she runs 3 miles per week.
so in
b is 3. the initial value.
increasement by 20% means she runs 1.2 times than before.
then a=1.2
so we have now:
and we got it!
Answer:
Simply put, the <u>commutative property of multiplication means that no matter how you order the numbers you are multiplying, you will get the same answer</u>. Addition also <em>shares the commutative property with multiplication, whereas division and subtraction do not</em>.
Explanation:
In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it. Most familiar as the name of the property that says "3 + 4 = 4 + 3" or "2 × 5 = 5 × 2", the property can also be used in more advanced settings.
