The variables are x and y. The constant is 250. The coefficients are 14 and 3
Use the given circumference C in the formula C=2(pi)(r) to solve for the radius r.
Then use that radius to get the area from the equation A=(pi)(r)^2.
Write the decimal number as a fraction
(over 1)
4.26 = 4.26 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator = 4.26 × 10 × 10 = 426
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 426 / 100
Simplifying our fraction
= 426/100
= 213/50
= 4 13/50
Answer: The correct answers are -3.45 and 1.45
Step-by-step explanation: The only problem you had was you rounded it to the tenths place instead of the hundredths place.
Sorry for getting back to you late.
C -3/2
Just multiply the second equation by -3/2
this will make the y term = -3/4y
so adding will eliminate the y terms.
