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:
A. 1 centimeter
Step-by-step explanation:
To solve you could use a proportion, in this case, 2/8=x/4. You can cross multiply to find the value of x. 8x=2*4, then simplify, 8x=8. Finally isolate the variable by dividing by 8. 8x/8=8/8, simplified that equals x=1.
Answer:
B = 12
Step-by-step explanation:
