Answer:
5 1/3
Step-by-step explanation:
16 - (2z-4)/3
Let z = 18
16 - (2*18-4)/3
Multiply inside the parentheses first
16 - (36-4)/3
Subtract inside the parentheses
16 - (32/3)
Divide inside the parentheses and change to a mixed number
16 - 10 2/3
Borrow 1 from 16 in the form of 3/3
15 3/3 - 10 2/3
5 1/3
No bc the width of the circular ring is only 12.67 inches
knowing circumference = pi * diameter, we can make the formula:
39.8 = (3.14)(diameter)
divide 39.8 by 3.15
diameter = 12.67 inches
12.67 inches is not greater than or equal to 18 inches

Answer:
a) 7(3x +7)
b) y(3y -1)
c) 4x^2(2 +x)
d) 2s^2t^2(12s +5t^2)
Step-by-step explanation:
These are factored by finding the greatest common factor of the given terms. Generally, that can be found by looking at the factors and finding the largest that is common to all terms.
__
a) 21 = 7·3; 49 = 7·7. The GCF is 7. Factoring that out gives ...
7(3x +7)
__
b) y is the only factor common to both terms.
y(3y -1)
__
c) 4 and x^2 are factors common to both terms, assuming the second term is 4x^3.
4x^2(2 +x)
__
d) 10 = 2·5; 24 = 2·12; the factors s^3 and s^2 share a factor of s^2; the terms t^2 and t^4 share a factor of t^2.
2s^2t^2(12s +5t^2)
Answer: 3x+10y=−80

Answer:
$14.24
Step-by-step explanation:
9.89+1.99=$11.88
11.88*1.07=12.71
12.71*1.12=$14.24
