Answer:
what are you trying the value of?
Answer:
Equation E, Equation B, Equation C are equivalent
Step-by-step explanation:
Given Equation:
0.6 + 15b + 4 = 25.6
Check all that applies
Equation A: 15b + 4 = 25.6
0.6 + 15b + 4 = 25.6
15b + 4 = 25.6 - 0.6
15b + 4 = 25
NOT CORRECT
Equation B: 15b + 4 = 25
0.6 + 15b + 4 = 25.6
15b + 4 = 25.6 - 0.6
15b + 4 = 25
CORRECT
Equation C: 3(0.6 + 15b + 4) = 76.8
0.6 + 15b + 4 = 25.6
Multiplying both sides by 3
(0.6 + 15b + 4) ×3 = 25.6 × 3
(0.6 + 15b + 4) ×3 = 76.8
CORRECT
Equation D: 15b = 25.6
0.6 + 15b + 4 = 25.6
NOT CORRECT
Equation E: 15b = 21
0.6 + 15b + 4 = 25.6
15b = 25.6 - 0.6 - 4
15b = 21
CORRECT
Equation E, Equation B, Equation C are equivalent
Answer:
is not a polynomial.
Step-by-step explanation:
Given : an expression
We have to check whether given expression is a polynomial or not.
An expression is said to be polynomial if it is the collection of constant and one or several variables having non negative integer power or degree.
Example :
For the given expression the variable term is X is having power of -6 which is negative.
Hence, is not a polynomial.
Answer:
13.3 hours
Step-by-step explanation:
% done by Nancy in 8 hours = 100% = 1
8 (% done by Nancy in 1 hour) = 1
% done by Nancy in 1 hour = 1/8
n = 1/8
Similarly,
% done by Nancy in 5 hours + % done by Carole in 5 hours = 1
5 (% done by Nancy in 1 hour + % done by Carole in 1 hour) = 1
n + c = 1/5
Since n = 1/8
% done by Carole in 1 hour = 3/40
Thus,
time taken by Carole to finish the job
