Answer:
x=18
QR=29
RS=29
QS=29
Step-by-step explanation: 2X-7=5x-61=x+11 solve for x since all sides are equal
Area of circle = pi r^, (r)radius is half the diameter so 9÷2=4.5 so in this scenario it would be 3.14×4.5^
3.14×4.5×4.5=63.6
circumference of circle= diameter×pi (3.14)
so 9×3.14=28.3
Answer:
10.756 esa seria la respuesta
Step-by-step explanation:
Answer:
Ameliorate retort, pertaining to preceding albeit contingent interrogate proximates subject to x = 12.
Step-by-step explanation:
Availing, exploiting, albeit maneuvering the Mathematic convention, Order of Operations (OO), the contiguous albeit proximate equation may ascertain as the preeminent imminent:
Groups: Not identified.
Exponents: Not identified, disparaging ₁.
Multiplication: Derived, pertaining to subtraction, 4 · (7/4x) = 4 · 21 <u>7x = 84</u>
Division: Derived, pertaining to multiplication, 7x = 84 ⇒ <em><u>x = 12</u></em>
Addition: Aggregate constants ⇒ 5/2x = 3/4x +21
Subtraction: Abate algebraic groups ⇒ 7/4x = 21
Steve did it perfectly, because he got the common denominator first, then expanded and subtracted.
