Answer:
(5c-9-a)/3
Step-by-step explanation:
1. subtract a from both sides to isolate the variable and its coefficient
5c-9-a = 3b
2. divide both sides by 3 to isolate b because 3b/3 = b
(5c-9-a)/3 = b

Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of
Step-by-step explanation:
A temperature falls from 0 to
in 
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is 


Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:

x° = - 3.5
x° = 
Thus per hour; the temperature falls at the rate of
First find the slope. m=(y2-y1)/(x2-x1)
m=(4225-1990)/(5-2)=745,
m is the slope, this represents the amount of money earned each month that the business operates.
so far we have:
y=745x+b, using any point we can solve for b, I'll use (2,1990)
1990=745(2)+b
1990=1490+b
500=b
b is the y-intercept which is $500, it represents the amount of moeny that the business started with.
Answer:
£40
Step-by-step explanation:
Sum the parts of the ratio 5 + 1 = 6 parts
Divide £48 by 6 to find the value of one part of the ratio
£48 ÷ 6 = £8 ← value of 1 part of the ratio
Thus the larger part of the ratio is
5 × £8 = £40
