First is multiplying
54 × 56 = 3,024
Now, add 9
3,024 + 9 = 3,033
At last, add y
3,033 + y = 3,033 + y
Your answer is: 3,033 + y
Hope this helps :)
<span>{x=2+y
{-6x-6y=-12
-6(2+y) -6y = -12
-12 - 6y - 6y = -12
-12y = -12 + 12
-12y = 0
y = 0
x = 2 + y = 2 + 0 = 2
Answer: x=2, y=0</span>
Answer:Lateral Surface Area is 672m^2
Step-by-step explanation:
Surface Area of Triangles= 8m*12m=96
Surface Area of Top & Bottom Rectangles= 12m*18m*2=432m^2
Surface Area of Middle Triangle=12m*18m=216
Total Surface Area= 216+432+96
672m^2
Call the number of courses ' C '.
Whatever it is, it will cost her [ 55 + 450C ].
How many courses can she get for $1,200 ?
55 + 450C = 1200
Subtract 55 from each side:
450C = 1145
Divide each side by 450 :
C = 1145 / 450 = 2.544...
She can only register for a whole number of courses, so<u> 2 </u>is the limit.
That will cost her (55 + 2x450) = (55 + 900) = $955
and she'll have $245 left over ... not enough for another course.
