X=7, y=3
because it is an algebraic method you have to solve for an x or y in either equation, and then plug that into the other equation. it’s helpful for these problems to check your work and plug the numbers back into the equations and the end for future reference !
Answer:
49x + 114
Step-by-step explanation:
[ [ fireplace ] x = area of 5
] x + 6
5x
patio = area of 5 + 49x + 114
5x + 19
(5x + 19) ( x + 6) = 5 + 19x + 30x + 114
(5 + 49x + 114) - (5 ) = 49x + 114
(area of patio and fireplace) - (area of fireplace) = (area of patio only)
Answer:
2. 31/6 3. -12/1 4. integer 5. rational number
Step-by-step explanation:
2. You multiply the 5 by 6/6, so it becomes 30/6, then add the 1/6. getting you the 31/6.
3. Since -12 is already an integer with no mixed part, you just put it over 1.
4. -12 is an integer, but is not a whole number because it is negative.
5. fractions are rational numbers

bc it is and im right haha
Here we have to find the probability 
. Now express the probability in terms of standard normal cumulative distribution function. That is 
.
Now you can look up the probability from the standard normal tables. Its value is
