-y = x + 3 . . . . this is the sides for the double lines
2y + 24 = x + 9 . . . . this is the sides for the single lines
To solve you need to substitute one equation into the other
-y = x + 3
y = -x - 3 . . . place this equation into the other equation where (Y) is
2y + 24 = x + 9
2 ( -x - 3) + 4 = x +9
-2x - 6 + 24 = x + 9
-2x +18= x+9
-3x = -9
x = 3 . . . substitute this answer into the equation and solve for (Y)
-y = x + 3
- y = 3 +3
-y = 3 + 3
y= -6
Answer:
P = 2t + 2u + 2v + 4w
Step-by-step explanation:
Answer:
D or 1-(17/29)^4
Step-by-step explanation:
This is because you need to figure out the probability that a selected marble is not blue, which is (17/29)^4. Then you can calculate the probability that one of them is blue by taking this number, and subtracting it from 1. This results in 1-(17/29)^4.
<h3><em>To multiply two 2-digit numbers without showing work, first multiply the ones digits together, then 'cross-multiply,' and finally multiply the tens digits together. Make sure to carry whenever a product exceeds 9. As you will see in the examples below, you must work your way from right to left to perform this trick.</em></h3><h3><em>HOPE IT HELPS !!!</em></h3>
1st hour 100+40×1=140 2nd hour 100+40×2=180 3rd hour 100+40×3=220. 4th hour 100+40×4=260. Im not sure what it means by process column but hope this helps.
