Solve with Quadratics

leonid [27]

Answer:

x = 1 ± $\sqrt{6}$

Step-by-step explanation:

Given

2x² - 4x = 10 ( divide through by 2 )

x² - 2x = 5

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = 5 + 1

(x - 1)² = 6 ( take the square root of both sides )

x - 1 = ± $\sqrt{6}$ ( add 1 to both sides )

x = 1 ± $\sqrt{6}$ ← exact solutions

Deja has two baskets of berries. One of the baskets has 3 3/8 pounds of berries and the other basket has 2 7/8 pounds of berries

ElenaW [278]

Answer:

(b) The number of pounds of berries each person would receive is $1\frac{5}{8}$ pounds.

Step-by-step explanation:

The amount of berries in first basket = 3 3/8 pounds

Now, $3\frac{3}{8} = 3+\frac{3}{8} = 3 + 0.375 = 3.375$

So, the amount of berries in first basket = 3.375 pounds

The amount of berries in second basket = 2 7/8 pounds

Now, $2\frac{7}{8} = 2+\frac{7}{8} = 2 + 0.875 = 2.875$

So, the amount of berries in second basket = 2.875 pounds

Now, the total berries = Berries in ( First + Second) basket

= 3.375 pounds + 2.875 pounds

= 6.25 pounds

So, the number of pounds each person would have = $\frac{\textrm{Total weight of viable berries}}{\textrm{4}} = \frac{6.25}{4} = 1.5625$

Now, $1.5625 = 1 + 0.5625 = 1 + \frac{5625}{10000} = 1 + \frac{5}{8} = 1\frac{5}{8}$

So, the number of pounds of berries each person would receive is $1\frac{5}{8}$ pounds.

Tony wants to calculate his average quiz score. The formula gives Tony’s average score A for a total of T points on n quizzes. T

Gnoma [55]

In calculating the average score, add the scores of each person and then divide it by the number of scores present. In this problem, Tony has forty seven points for five different quizzes. You are required to calculate for the average score of Tony. The formula is A = T/n, where A is the average score, T is the score, and n is the number of quizzes.

A = T/n
A = 47/5
A = 9.4 
Therefore, Tony has an average of 9.4 points in five different quizzes.
