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

Which system of linear equations has the ordered pair (4, –5) as a solution? 2 x minus 5 y = negative 30 and 7 x + 4 y = negative 19 6 x minus y = negative 29 and 8 x + 3 y = negative 17 3 x minus 2 y = 22 and 2 x + 9 y = negative 37 5 x minus 6 y = 49 and x + 8 y = negative 27
Answer:

Step-by-step explanation:
i took test
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?
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%

what is ─6d – 10 = 10 – 4d solved for the variable
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
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
Hence A is 0.36

1. On Monday, Sarah
started reading her book
that has 26 chapters. On
Monday, she read 9/26 of
her book. On Tuesday she
read 6/26 of her book. How
much does she have left to
read?
Answer:
Sara have 11 chapters left to read.
Step-by-step explanation:
Total chapters Book has = 26
On Monday Sarah read = [tex]\frac{9}{26}\ of \ 26 \ chapters = \frac{9}{26}\times \ 26 \ chapters=9 \ chapters[/tex]
On Tuesday Sarah read = [tex]\frac{6}{26}\ of \ 26 \ chapters = \frac{6}{26}\times \ 26 \ chapters=6 \ chapters[/tex]
Total Chapters read by Sarah = [tex]9+6= 15 \ chapters[/tex]
Chapters left to read by Sarah = [tex]26-15 = 11 \ chapters[/tex]
So, Sara have 11 chapters left to read.
