a) \: 17 - 3 \frac{1}{5}

17-\frac{3\times 5+1}{5}

LCM=5

17-\frac{16}{5}

17\times \frac{5}{5}-\frac{16}{5}

\frac{85}{5}-\frac{16}{5}

\frac{69}{5}

13 \frac{4}{5}

b) \: 2\frac{1}{5}+4\frac{1}{4}+\frac{7}{10}

6+\frac{1}{5}+\frac{1}{4}+\frac{7}{10}

LCM=20

6+\frac{4}{20}+\frac{5}{20}+\frac{14}{20}

6+\frac{4}{20}+\frac{5}{20}+\frac{14}{20}

6+\frac{23}{20}

6+1\frac{3}{20}

2x2 − 1 = 3x + 4 Which equation correctly applies the quadratic formula?
NNADVOKAT [17]

Standard form: ax^2 + bx + c = y

Steps to simplify:

2x^2 - 1 = 3x + 4

~Subtract (3x + 4) to both sides

2x^2 - 1 - 3x + 4 = 3x + 4 - 3x + 4

~Simplify

2x^2 - 3x - 5 = 0

(a = 2, b = -3, c = -5)

Now that we know what these values are, we can use the quadratic formula to solve.

x=\frac{-b-+\sqrt{b^2-4ac} }{2a} \\x = \frac{-(-3)-+\sqrt{-3^2-4(2)(-5)} }{2(2)}\\x= \frac{-3-+\sqrt{49} }{4} \\x=\frac{3-+7}{4} \\x = \frac{10}{4}~or~\frac{-4}{4}  \\x=\frac{5}{2}~or~-1

Answer: x = 5/2 or x = -1

Best of Luck!

0.75,1.75,2.75,3.75 is arithmetic or geometric?
Semenov [28]

Hello from MrBillDoesMath!

Answer:

Arithmetic


Discussion:

First glance at the numbers shows each term is 1 larger than the preceding terms. So we are adding the constant 1 to each term to get the next term. This is an arithmetic progression.

Thank you,

MrB
