Answer:
1.) 1/2x = 32
2.) 3x = 18
3.) x/7 = 4
4.) 5m=105
divide both sides by 5
m= 21
5.) -2c=-32
divide both sides by -2
c=16
6.) x/4=-44
multiply both sides by 4
x=-176
7.) s/-3 = -21
multiply both sides by -3
s=63

Katrina has $210 in her savings account. She plans to buy books for her friends for Christmas. The books cost $7 per book. Which equation best represents this situation? Let y represent the amount of money in Katrina's account and x represents the number of books she purchases.
what is the correct answer
y=210-7x
y=7x+210
y=210x+7
y=-7+210x
Answers
Answer:
Option 1 y = 210 - 7x
Step-by-step explanation:
Since she will be buying "x" amount of books she will lose money because she has to pay for them. Each book costs $7 so if she buys "x" books she will lose 7x dollars. Therefore the right equation would be...
y = 210 - 7x (which is the first option)

What is trigonometric identity?Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.
It is given that in the right-angle triangle ABC the three sides are AB = 4.24, BC = 3 and AC = 3.
The value of cosine is the ratio of the base of the right-angle triangle and the hypotenuse of the right-angle triangle.
The value of cosA is calculated as below:-
cosA = 4.24 / 3
The value of cosB is calculated as below:-
cosB = 4.24 / 3
Calculating the ratio of cosA and cosB.
cosA / cosB = [ 4.24 / 3 ] ÷ [ 4.24 / 3 ]
cosA / cosB = 1

-7x -4y = -15
What is this in a ordered pair? (x,y)
Answers
Answer:
x=1,y=2
-2x-4y= -10 maltiple by -1 then 2x +4y
-7x-4y= -15
therfore 2x+4y=10
-7x-4y=-15 to find x or y you must zero one of them
ther fore 4y-4y=0
then 2x+(-7x)= -5x
-5x=10 +(-15) =-5
-5x = -5
divide by -5 both side,
x =1
to get the value of y the value of x supersed in to equation
-2(1) -4y = -10
-4y =-10 +2
-4y = -8 both dived by -4

Write an expression that is equivalent
to 2/8b+(3/8b+4/5)
Answers
Answer: 5/8b + 4/5
EXPLAIN: It's too easy explain it yourself. (LOL)
The value of the equation is A = ( 5/8 )b + 4/5
What is an 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.
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 data ,
Let the equation be represented as A
Now , the value of A is
A = ( 2/8 )b + ( 3/8 )b + ( 4/5 ) be equation (1)
On simplifying the equation , we get
A = [ ( 2/8 )b + ( 3/8 )b ] + 4/5
A = ( 5/8 )b + ( 4/5 )
On further simplification , we get
A = ( 25b + 32 ) / 40
Therefore , the value of A is ( 5/8 )b + ( 4/5 )
Hence , the equation is A = ( 5/8 )b + ( 4/5 )

Which correlation coefficient represents the strongest downward trend in a data set? -0.83 -0.23 0.12 0.92
Answers
Answer: -0.83
Step-by-step explanation:
A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.
-1 ≤ r ≤1
For downward trend r is negative.
For strong correlation r should be closer to 1 or -1.
From the given correlation coefficients -0.83 is both negative and closer to -1.
Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83
