Answer 1

Answer:

[tex]\frac{31}{45}x[/tex]

__________________________________________________________

Step-by-step explanation:

We are given:

3[tex]\frac{1}{5}x[/tex] + 10[tex]\frac{7}{9}x[/tex] - 2[tex]\frac{2}{5}x[/tex] - 10[tex]\frac{8}{9}x[/tex]

Concepts used:

Evaluating Mixed fractions and Adding like terms

Simplifying the Mixed Fractions:

to simplify these mixed fractions, we will multiply the whole number part with the fraction's denominator and add that to the numerator.

The number formed will be given the same denominator as of the fraction part in the number

After simplifying these mixed fraction, we get:

[tex]\frac{16}{5}x + \frac{97}{9}x - \frac{12}{5}x - \frac{98}{9}x[/tex]

Adding and Subtracting the like terms:

to simplify our calculations, we will pair the numbers with the same denominator

[tex](\frac{16}{5}x - \frac{12}{5}x) + (\frac{97}{9}x - \frac{98}{9}x)[/tex]

Simplifying the terms in the brackets

[tex]\frac{4}{5}x - \frac{1}{9}x[/tex]

Taking the LCM and simplifying

[tex]\frac{36}{45}x - \frac{5}{45}x[/tex]

Since the denominators are equal, the numerators can now be subtracted

[tex]\frac{31}{45}x[/tex]

Therefore, simplifying the given series of number gives us 31x/45

The ordered pair (4, -5) satisfies the equation

3x- 2y= 22

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

We have ordered pair (4, -5)

First equation, 2x - 5 y= -30

So, 2(4)- 5(-5)= 8 + 25= 33

Second equation,7 x + 4 y = -19

So, 7(4)+4(-5)= 28 -20= 8

Third equation, 6x - y= -29

So, 6(4) +5= 24+ 5 = 29

Fourth equation, 8 x + 3 y= -37

So, 8(4) + 3(-5)= 32 - 15 = 17

Fifth equation, 3x- 2y= 22

3(4)- 2(-5)= 12 + 10 = 22

sixth equation, 2x+ 9y = -37

2(4) + 9(-5)= -37

seventh equation, 5x- 6y= 49

5(4) - 6(-5)= 20 + 30 = 50

eight equation, x+ 8y= -27

4+ 8(-5)= -36

The half-life of radioactive radium (226Ra) is 1599 years. What percent of a present amount of radioactive radium will remain after 275 years?

Answers

Answer:

88.76%

Step-by-step explanation:

Given that :

Half life of radium = 1599 years

Percentage that will remain after 275 years

Using the relation :

y = Ae^kt

Where ; A = mass of radium and t = half life = 1599, A = initial mass

By 1599, the mass of radium will be half its initial

Hence,

y = initial / 2 = A /2

A/2 = Ae^kt

To obtain the value of k

0.5 = e^1599k

In0.5 = 1599k

k = (In0.5)/1599

k = - 0.0004335

Hence,

y = Ae^-0.0004335t

Amount of radium. After 275 years : t = 275

y = Ae^-0.0004335*275

y = A0.8876191

y = 0.8876191 of intial amount

Hence, 0.8876191 * 100%

= 88.76%

Answers

Answer:

d = -10

Step-by-step explanation:

(d is the variable)

-6d - 10 = 10 - 4d

+4d        +10

-2d = 20

-2d/-2    20/-2

d = -10

:)

Answer:

d = 2

Step-by-step explanation:

Simplify both sides.

6d − 10 = 10 − 4d

6d + −10 = 10 + −4d

6d − 10 = −4d + 10

6d − 10 + 4d = −4d + 10 + 4d

10d − 10 = 10

10d − 10 + 10 = 10 + 10

10d = 20

20 ÷ 10 = 2

A varies inversely as the square of B. If A is 1 when B is 3, find A when B is 5

Answers

Answer:

0.36

Step-by-step explanation:

A= K/B^2

K= A × B^2

K= 1 × 3^2

K= 1×9

K= 9

Therefore if B is 5 then A can be calculated as follows.

K= A × B^2

9= A × 5^2

9= A × 25

9= 25A

A= 9/25

A= 0.36
