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.

Answer:
it's 19
Step-by-step explanation:
18 - 3 = 15
so the difference between them is 15
so since you wanna fine the "?" on the right, you would add 4+15, which gives you 19
(also 3 and 4 four are only one number apart, so you could have just added (+1) to 18) :)

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

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%
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
