Y=-5x-30.
Subtract from each side (1/5y=-x-6 )
Then multiply by 5/1 on both sides to get rid of the 1/5 (y=-5x-30)
The formula for finding the radius of a circle while only knowing the circumference is r=C ÷ 2π. Substituting the value 10 for C, and 3.14 for π, we get:
r=10 ÷ 3.14 · 2 Now we divide 10 by 6.28
r≈1.59
Let's use <em>j</em> to represent Jiri's age.
If Pamela is 6 years younger that Jiri, her age can be represented by <em>j - 6</em>.
Since the sum of their ages is 64, we can setup the equation j + (j - 6) = 64.
Simplifying on the left, we have 2j - 6 = 64.
Adding 6 to both sides, we have 2j = 70.
Dividing both sides by 2, we have j = 35.
So Jiri is 35 years old and Pamela is 6 years younger or 29 years old.
Answer:
3.5 ( 12 + h)
Step-by-step explanation:
From the given information:
The expression 42 + 3.5h is factored out by taking the coefficient of the variable term is 3.5
So factoring 3.5 from the expression 42 + 3.5h, we get:
= 3.5 ( 12 + h)
Answer:
7 radians
Step-by-step explanation:
In a circle, an angle measuring 2π radians intercepts an arc of length 14π. Find the radius of the circle in simplest form.
Since our Angle in in radians
The formula for Arc length = S = rθ
S = 14π
θ = central angle = 2π radians
Hence
r = S/θ
r = 14π/2π radians
r = 7 radians
Radius = 7 radians
