Answer:
10 (10.28)
Step-by-step explanation:
this can be solved with a proportion
6/7 = x/12 cross multiply
7x = (6) (12)
7x = 72
72/7
10.3
These 5 bottles with lemonade which contains 150 millilitres in each bottle so it would be 150 x 5 to find how many millilires there is in all
A triangle is equal to 180. Using that, we can make a equation.
6x-3 + 3x+6 + 5x = 180
Combining the like terms, we get:
14x+3 = 180
Subtract 3 on both sides.
14x = 177
Finally, divide 177 by 14.
x = 177/14 or about 12.6
Answer:

Answer:
3.5 =k
Step-by-step explanation:
If the table is proportional, the equation is
y = kx
To find k
y/x =k
14/4 = k
7/2=k
3.5 =k
