Answer:
10x + 18
Step-by-step explanation:
First, we need to add like terms. Like terms are terms that are alike. For instance 8x and 2x are like terms. 15 and 3 are also like terms.
So, we have to add 8x plus 2x and 15 plus 3. That’s comes out to 10x plus 18.
Therefore, this expression is equivalent to 10x + 18.
1 3/5 is the awncer you are looking for because 4/5 is equal to .8 so .8 times 2 is 1.6 or 1 6/10 it simplified to 1 3/5
Answer:
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch (0.167) shirts.
Step-by-step explanation:
Mike can stitch 7 shirts in 42 hours
to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.
He can stitch 1 shirt in = = 6 hours
Now we calculate the work done in one hour.
He can stitch in 1 hour = shirts or 0.167 shirts
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch shirts.
cos(a-b) = cos(a)cos(b)+sin(a)sin(b)
