Answer:
and 20.5x
and 6.2y
Step-by-step explanation:
-3-x/5+6.2y+20.5x-3/8y
We are given an expression with 5 terms
The terms that has same variables with same exponent are like terms. WE combine only like terms. Constants are also like terms.
In the given expression , the fractions and 20.5x have same 'x' . so they are like terms. we can combine these terms.
the fractions and 6.2y have same 'y' . so they are like terms. we can combine these terms.
Answer:
∠ A ≈ 16.67°
Step-by-step explanation:
Using the Sine rule in Δ ABC
= 
, substitute values
= 
( cross- multiply )
16 sinA = 8 sin35° ( divide both sides by 16 )
sin A = 
, thus
∠ A = 
( ) ≈ 16.67° ( to 2 dec. places )
Answer:
you are right
Step-by-step explanation:
Because, well, without them how are you able to add and subtract fractions :D
It is according to the laws of mathematics that you cannot add or subtract fractions that have different denominators to each other. So you need to make your fractions having the same denominator so that they are able to be added or subtracted (hence the equivalent fractions - making the denominators the same are making the fractions equivalent)
1 1/2 plus 3/4 equal 9/4, and 9/4 divided by 1/8 equal 18
