Answer:
1.5 hours
Step-by-step explanation:
we know that
1) Martha can paint a room in 2 hours
so
Martha can paint the 100% of the room in 2 hours
Find out what percentage of the room she can paint in an hour
using proportion
2) Jamie can paint a room in 6 hours
so
Jaimie can paint the 100% of the room in 6 hours
Find out what percentage of the room she can paint in an hour
using proportion
3) In one hour Martha and Jamie can paint
so
using proportion
Find out how long will it take them to paint the 100% room together
The solution would be x = 0, x = 3
Answer:
You have your x and y mixed up
Step-by-step explanation:
Look at your table. You labeled y1 and y2 where the x's are. y2 = 8, y1 = 4, x2 = 12 and x1 = 6. The slope then is (8-4)/(12-6) which is 4/6 or 2/3. You did run over rise instead of rise over run. Be careful. I see that a lot when I teach the concept to beginners.
Answer:
(3•5•2a3b4)
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
-15ab • (0 - (2a2 • b3))
Step 2 :
Multiplying exponential expressions :
2.1 a1 multiplied by a2 = a(1 + 2) = a3
Multiplying exponential expressions :
2.2 b1 multiplied by b3 = b(1 + 3) = b4
