What is 10 - 4 and 2/3?

Ymorist [56]

10 - 4 2/3

First, we convert mixed fraction into improper fraction.

4 2/3 = ((4*3)+2)/3 = 14/3

In subtracting fractions:
1) Both must have the same denominator.
10 is 10/1 and 14/3 have different denominators.

2) Once they have the same denominator, then subtraction may be performed.

10 - 14/3 = 10 * 3/3 - 14/3 = 30/3 - 14/3 = 16/3

3) 16/3 must be simplified.

16/3 = 5 1/3

10 - 4 2/3 = 5 1/3

Evaluate the following expressions for a = -3,b=2,c=5

Ksju [112]

Hey!

----------------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), and (d = -4).

----------------------------------------------------------------------

Solution #1:

$=\frac{a-4b}{3c+2d}$

$=\frac{(-3) - 4(2)}{3(5) + 2(-4)}$

$=\frac{(-3) - 8}{15 +( -8)}$

$=\frac{-11}{7}$

≈ 1.57

----------------------------------------------------------------------

Solution #2:

= a - 4b / 3c + 2d

= (-3) - 4(2) / 3(5) + 2(-4)

= (-3) - 8 / 15 + (-8)

= (-3) - 0.53 + (-8)

= (-3.53) + (-8)

= -11.53

----------------------------------------------------------------------

Solution #1 Answer: 1.57

Solution #2 Answer: -11.53

What’s the answer to this?

Hoochie [10]

Answer:

The missing term is:

$a_2=14$

Step-by-step explanation:

Considering the geometric sequence

$2,\:?,\:98,\:...$

Here,

$a_1=2$

$a_3=98$

$a_2=?$

The general term of a geometric sequence is given by the formula:

$a_n=a_1\cdot \:r^{n-1}$

where $a_1$ is the initial term and $r$ the common ratio.

as

$a_3=a_1\cdot \:r^{3-1}$

$98=2\cdot \:r^{3-1}$ ∵ $a_1=2$

$\mathrm{Switch\:sides}$

$2r^{3-1}=98$

$\mathrm{Divide\:both\:sides\:by\:}2$

$\frac{2r^{3-1}}{2}=\frac{98}{2}$

$r^{3-1}=49$

$r^2=49$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$r=\sqrt{49},\:r=-\sqrt{49}$

$r=7,\:r=-7$

Taking positive value of $r = 7$

$a_2=a_1\cdot \:r^{n-1}$

putting $r = 7$

$a_2=2\cdot \:7^{2-1}$

$a_2=2\cdot \:7$

$a_2=14$

So, the sequence becomes $2,\:14,\:98,\:...$

Therefore, the missing term is:

$a_2=14$
