Answer:
2.83
Step-by-step explanation:
85 divided by 30 = 2.83
.25 times 2.83 = .70 cents
P= a+b+c = 76
side a = 2b = 30
side b = b = 15
side c = 2b + 1 = 31
For this case we have the expression:
"the square root of 4" is represented algebraically as:

Then, we can express the given statement as:

They are similar terms, we can subtract:

By definition of power properties we have that:
![\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20n%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bn%7D%20%7Bn%7D%7D%20%3D%20a)
Then the expression is reduced to:

Answer:

Answer:
63
Step-by-step explanation:
x = # in ones place
y = # in tens place
x + y = 9
y = x - 3
substitute:
x + x-3 = 9
2x - 3 = 9
2x = 12
x = 6
y = 3
