The original expression evaluates to 54.4 as shown in the first working.
_____
For some reason, 3.4 got transcribed to be 1.7 in the 3rd line of the second working. There is no math operation in the expression that requires 3.4 to be divided by 2.
I believe your mistake is that you are trying to use the sector area formula ti find arc length when there is already a formula for it.
The formula for it is
So first substitute the values in and then simplify!
Now simplify!
21 × 118 is 2478 so it's
When divided ou and multiplied, this is 21.62cm!
It's 8 because the number in front of the variable is the slope, while the past 30 is the y intercept
So 6.5 inches long in scale, but every 2 in is 5 yards.
Divide 6.5 by 2. This gives you 3.25. Then multiply by 5 to get yards.
It’s 16.25 yards long.
Answer:
First, take x off of both sides making it: “5 -4 = 3 + 10”
Then subtract 3, making it “3(-7) = 10”
Then do 3 multiply 3 by -7, getting -21 = 10
that is how you would find out the equation is false
