Answer:
x=5.35
Step-by-step explanation:
2x - 1.7 = 9
2x - 1.7 + 1.7 = 9 + 1.7
2x = 10.7
2x/2 = 10.7/2
x=5.35
Hope this Helps :)
Answer:
b=1-a
Step-by-step explanation:
Inside parenthesis
1/1=1
(replace it with that)
Open parenthesis
a=2-1-b
simplify numbers
a=1-b
isolate b
a-1=-b
multiple each side by negative 1
1-a=b
For this case, the first thing we must do is define a variable:
x: number of hours
y: number of trials
We write the equation that represents the problem:
y = (25/4) x
For 35 essays we have:
35 = (25/4) x
Clearing x:
x = 5.6 hours
Answer:
it will take him to grade 35 essays about:
x = 5.6 hours
the constant of this variation is:
25/4 essays / hour
Answer:
17/k
Step-by-step explanation:
The algebraic expression is to divide 17 by k
17/k This can't be simplified because there is a variable in the denominator.
Answer: m=9
