The proportion would go as follows:
2 C
5 = 145 Its hard to type that but 2 would go over the 5 and an equals sign would be in the middle, then C over 45. To solve then take 145 times 2 and divide it by 5.
Hope this helps.
<span>So we want to know how much clay did Joseph add after he built the cone. So the formula for the volume of the cone is V=(1/3)*pi*r^2*h where r is the radius and h is height. We know h1=12cm and r1=6cm, r2=6cm and h2=18 cm. So to get the amount of added clay Va we simply subtract the volume of the clay of the first cone V1 from the volume of the second cone V2: Vd=V2-V1=(1/3)*pi*(r1^2)*h1 - (1/3)+pi*(r2^2)*h2. Va=678.24 cm^3-452.39 cm^3= 266.08 cm^3.</span>
-5.55 - 8.55c + 4.35c
-8.55c + 4.35c = -4.2c
-5.55 - 4.2c is the answer.
An algebraic expression is an expression that includes constants, variables, and the algebraic operations (add, subtract, multiply, divide.
the answer is C................................
