Answer:
no
Step-by-step explanation:
3y+3 doesnt equal 9y+3
Answer:
Nope!
Step-by-step explanation:
9 times y is going to be 9y even if 9 time 1/3 is 3
60 = 100%
6 = 10%
24 = 40%
ANSWER: 24
Answer:
The weight of the larger box is 18.75 kg
The weight of the small box is 6.75 kg
Step-by-step explanation:
Let
x -----> the weight of large box
y ----> the weight of small box
we know that
The system of equations is equal to
9x+7y=216 -----> equation A
3x+5y=90 -----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (18.75,6.75)
therefore
The weight of the larger box is 18.75 kg
The weight of the small box is 6.75 kg

Step-by-step explanation:
Total amount of the colored pencils is given by the equation A = $ 12.40
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 amount of the color pencils be represented as A
Now , the equation will be
The total purchase amount by Kim = $ 21.35
The amount for the poster = $ 8.95
So ,
The amount for the color pencils A = total purchase amount by Kim - amount for the poster
Substituting the values in the equation , we get
The amount for the color pencils A = $ 21.35 - $ 8.95
On simplifying the equation , we get
The amount for the color pencils A = $ 12.40
Therefore , the value of A is $ 12.40
Hence , the amount for the color pencils is $ 12.40

Answer:
the answer is 'undefined'
Step-by-step explanation:
Cot is defines as (cos x)/(sin x)
So we can rewrite our expression as...
(cos 180°)/(sin 180°) + (cos 180°)/(sin 180°)
or
2(cos 180°)/(sin 180°)
Cos 180° = 1, sin 180° = 0 (you get these from the unit circle)
so we have
2(1/0) = 2/0, which is undefined, because we don't divide by zero
