The answer is x=0.6
25-3x-5=2x+16+x
20-3x=3x+16
20-6x=16
-6x=-4
x=0.6
Answer:
A =28.26 inches^2
Step-by-step explanation:
The diameter is 6 so the radius is d/2 = 3
The area is given by
A = pi r^2
A = pi (3)^2
A = 9pi
Using 3.14 for pi
A = 9 * 3.14
A =28.26 inches^2
If x equals 3 then y must equal 1.2
Like terms have the same variables and exponents. Constants are also like terms.
The given expression is
Зу + 3y + 5+ 7x^3 - у - 6 - 7x^3
By combining like terms, it becomes
7x^3 - 7x^3 + 3y + 3y - y + 5 - 6
= 5y - 1
Since ∆STQ ≈ ∆SRQ, then
x=6
m<SRQ= 83°
m<RSQ= 42°
