10x6=60 so 180-60=120 and 120 divided by 8 is 15 so the answer is 15 hours
Answer:
The coordinates are
and
.
Step-by-step explanation:
First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:
(1)
Where
is the vector translation.
If we know that
and
, then the vector translation is:



Then, we determine the coordinates for Y' and Z':






The coordinates are
and
.
Solve for m.
Add 7 to both sides to get 3m=15
Then divide by sides by 3 to get m=5.
The final answer is m=5.
He should make 20 dining chairs, and 10 rocking chairs. Making a profit of 2100$
10 rocking chairs x 2hrs = 20hrs
20 dining chairs x 1 = 20hrs
20hrs + 10hrs = 30hrs
90 x 10 = 900$
20 x 60 = 1200$
900 + 1200 = 2100$
Use distributive property.
5 x 8x =40x
5 x 3y =15y
5 x -4 =-20
so your answer would be 40x+15y-20
Hope this helps!
