K so you have to set 2 equations like this
x meaning the amount of adults
and y meaning the amount of kids
x+y=11
13.5x+8.25y=111.75
Then use substitution method and you get
x=11-y from the first equation
plug that in to the second and you get
13.5(11-y)+8.25y=111.75
Solve for y in that equation by distributing and then combining like terms
148.5 - 13.5y + 8.25y = 111.75
148.5 - 5.25y = 111.75
Then, you need to subtract 148.5 from each side and cancel the negatives
5.25y=36.75
solve for y and you get
36.75/5.25 = 7
y=7

Answer:
52.5 pounds
Step-by-step explanation:
7/8 times 60=52.5
Plot the point 123 on the line and go to the right 235 units.
because there is the big number, just draw the line begin with 123 to 400.
each unit might increase by 10.
123, 133, 143, etc
you can increase bigger if you want
Step-by-step explanation:
6x-7+3x-29=180 (corresponding angle)
9x-36=180
9x=180+36
9x=216
x=24.
6x-7=8y+17
144-7-17=8y.
8y=120
y=15.
therefore, x=24°, y=15°.
hope this helps you.
X and y are the half length of the largest and smallest diameter of the ellipse.
Area of the Ellipse , a = πxy
To find: Equivalent Equation for y.
Consider,
a = πxy
πxy = a
(πx)y = a
transpose πx to RHS,
y = a ÷ ( πx )
Hope this helps!
