Answer:
Step-by-step explanation:
Represent Celsius with C and Fahrenheit with F.
So, we have:
Solving (a): Represent as a linear equation
First, we calculate the slope:
This gives:
The linear equation is then calculated using:
Where
Make F the subject
Solving (b): The value of F when C = 30
Substitute 30 for C in
Answer:
C) x=35
Step-by-step explanation:
First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:
4x + 2(3x+5) = 360
By now using our linear equation skills, we get:
10x+10=360
10x=350
x=35
The degree amount of x for c) is 35 degrees.
The answer is d. it isn’t an exact number
Answer is -10
(x-3)-2(x+6)= -5
x-3-2x-12= -5
-x= -5+12+3
-x=10
x= -10
