So first we divide 140 by 7 because our ratio is a total of 7 dollars to get 20
So we multiply both sides of the ratio by 20 to get a ratio of 40:100
We can check our answer and it is right because 100+40=140
Answer:

Answer:
if you divide it by 2, you would have 128 slices because 256 ÷ 2 gives you 128, and when you multiply 128 by 2 you get 26.
Step-by-step explanation:
We will take the common terms in the expressions-
Here in the expression, 3y is a common term.
So,


So, the answer is
Let
x-----------> <span>uniform width surrounding the picture
we know that
(10+2x)*(12+2x)=224-----> 120+20x+24x+4x</span>²=224
4x²+44x+120-224=0
4x²+44x-104=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
x=2 in
the answer is2 inches
