Solve the Quadratic Equation By Completing the Square<br> b^2-15b-54=0
vladimir1956 [14]
b^{2}-15b-54=0. \newline&#10;b^{2}-15b=54. \newline&#10;b^{2}-15b+(\frac{15}{2})^{2}=54+(\frac{15}{2})^{2}. \newline&#10;(b-\frac{15}{2})^{2}=\frac{441}{4}. \newline&#10;b-\frac{15}{2}=\pm\frac{21}{2}. \newline&#10;b=\pm\frac{21}{2}+\frac{15}{2}. \newline&#10;b_1 = -3, b_2 = 18.

The sum of three consecutive numbers is 276. What is the smallest of these intengers?
shtirl [24]

Answer:

91

Step-by-step explanation:

Let x be the smallest one:

● x is the first number

● x+1 is the second number

● x+2 is the third number

The sum of these numbers is 276

● x+(x+1)+(x+2) =276

● x+x+1+x+2 = 276

● 3x + 3 = 276

Substract 3 from both sides:

● 3x+3-3 = 276-3

● 3x = 273

Divide both sides by 3

● (3x)/3 = 273/3

● x = 91

So the smallest one is 91

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling. Abha collected 178
kompoz [17]

Answer: [911,∞)


Step-by-step explanation:

Given: S be the number of cans collected by Shane.

Since,  Abha collected 178 more cans than Shane did.

Then, the number of cans collected by Abha = S+178

Also, Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling.

So, S+178+S\geq2000

\\\Rightarrow\ 2S\geq2000-178\\\Rightarrow2S\geq1822\\\Rightarrow\ S\geq911

Hence, the solution set of the inequality will be [911,∞)
