Hello! I can help you with this question! To find the unit rate, we’ll have to divide total by number of units. Or in this case, miles/gallons. 325.4/17.3 is 18.809 and other numbers, or 18.81 when rounded to the nearest hundredth. If you’re looking for the answer to the nearest hundredth, the answer is 18.81 mpg. Or, if you’re looking for the answer to the nearest whole number, the answer is 19 mpg.
Answer:
The answer is below
Step-by-step explanation:
A linear equation is represented by the equation y = mx + b, where m is the rate of change, b is the value of y at x = 0, y is a dependent variable and x is an independent variable.
a) Given that number of chirps per minute, C is dependent on the temperature, T, when T = 45 degrees, C = 0, this can be represented as (45, 0).
Also at 75 degrees, C = 126 it can be represented as (75, 126).
Using (45, 0) and (75, 126), we can determine the equation of the line from:
b) At t = 90°:
C = 4.2(90) - 189
C = 189 chirps per min
Answer:
Divide 2.5 on both sides
Step-by-step explanation:
2.5x = 5.7
Divide both sides by 2.5. The inverse of multiplication is division. The x variable must be isolated on one side.
(2.5x)/2.5 = 5.7/2.5
x = 2.28
It would be D! feel free to mark me brainlist!
