x= small frames
y = large frames
6x+15y = 114
x+y = 13
solve for x
x=13-y
substitute into 6x+15y = 114
6(13-y) +15y = 114
distribute
78 -6y +15y = 114
combine like terms
78 +9y = 114
subtract 78 from each side
9y = 36
divide by 9
y =4
x = 13-y
x = 13-y
x=9
Answer: 9 small frames and 4 large frames
Answer:
-6-b
Step-by-step explanation:
4(1-2b)+7b-10
Multiply what's in parantheses
4(1)=4
4(-2b)=-8b
4-8b+7b-10
Combine like terms
4-10 -8b+7b
-6-b
Hope this helps :)
Answer:
240in
Step-by-step explanation:
Total surface area of a square based pyramid is expressed as
TSA = 1/2pl + B
p is the perimeter of the base
p = 4L
p = 4(2)
p = 8in
l = 4in
B is the base area = 2 * 2 = 4in^2
TSA = 1/2 * 8 * 4 + 4
TSA = 16 + 4
TSA of one game piece = 20in
Since we have 12 game pieces, total surface area will be 20 * 12 = 240in
What in proper????????????
