Answer:

5xy/27

Step-by-step explanation:

The product of the two numbers x and y = xy

Five times the product of the two numbers x and y = 5xy

then,

divided by a third number 27 = 5xy/27

The expression will be : 5xy/27

Nick my luts

Answer:

6 weeks

Step-by-step explanation:

Let x represent the weeks

[tex]25=10+ (10x-7.5x = 2.5)[/tex]

[tex]25-10=2.5x = 15[/tex]

[tex]\frac{15}{2.5}=x \\(150/25)\\x=6[/tex]

Carol and Cathy will have same saved amount after 6 weeks.

What do you mean by algebraic expressions ?

Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.

It is given that Carol started with $25 and saved per week an amount of $7.50 whereas Cathy started with $10 and saved per week amount of $10.

Let's assume that after x no. of weeks they will have same saved amount.

So , we can write an algebraic expression which is :

25 + (7.5 × x) = 10 + (10 × x)

Now , reordering the like terms we get :

10x - 7.5 x = 25 - 10

Simplifying this we get :

2.5 x = 15

or

x = 15 ÷2.5

or

x = 6 weeks

Therefore , Carol and Cathy will have same saved amount after 6 weeks.

2. Shipping and handling is only charged once?

If so:

[tex]C=13n+1.95[/tex]

[tex] ({ \frac{7}{3} })^{x} = {A}^{2x} \\ [/tex]

[tex] ({ \frac{7}{3} })^{x} = {A}^{ {2}^{x} } \\ [/tex]

Answer:

Three arithmetic means between -16 and 4 are : 20 , 10 and  [tex]\frac{20}{3}[/tex]

Step-by-step explanation:

we have to find out three arithmetic means between -16 and 4

-16 , ____  , ____ , ____ 4

so , lets take the mean like this ,

-16 ,  -16+d , -16+2d ,-16+3d , 4

First mean -: -16 +d = 4

                   d= 4+16

                   d = 20

second mean -: -16 +2d = 4

                            2d=  4+16 = 20

                             d= [tex]\frac{20}{2}[/tex]

                             d= 10

third mean -: -16+3d = 4

                         3d = 20

                          d=[tex]\frac{20}{3}[/tex]

Therefore , all the three arithmetic means between -16 ad 4 are 10 , 20 and  [tex]\frac{20}{3}[/tex] .

Answer:

Step-by-step explanation:

Distance formula:

d = rt

where d = distance, r = average speed and t = time travelled.

They told us that an object travels 30 meters in 20 seconds.

So we can say d = 30 and t = 20

If you put these values back into the distance formula you get:

d = rt

30 = r times 20

30 = 20 r

So now we want to find what "r" (average speed) is.

Divide both sides by 20.

20 r = 30

r =  [tex]\frac{30}{20}[/tex] = 1.5 meters per second.

Answer:

You have 12 quarters and 30 dimes.

Step-by-step explanation:

If you have an equation that says 10d+25q= 600 cents (d meaning dime and q meaning quarter) and have another equation that says d+w=42, then you could use those two equations to solve the problem.

Answer:

Sin theta= a/c

= 5/7.8

= 0.64

= 1

Step-by-step explanation:

Lets find the hypotenuse first by applying Pythagorean theorem.

a^2+b^2=c^2

(6)^2+(5)^2=c^2

36+25=c^2

61=c^2 (FIND SQUARE ROOT)

7.8=c

Sin theta= a/c

= 5/7.8

= 0.64

= 1

Cos theta= b/c

= 6/7.8

Tan theta= a/b

= 5/6

Answer:

Step-by-step explanation:

3x^2 + 8x - 16 - SOMETHING = x^2 - 4

Re-arranging left and right:

SOMETHING = 3x^2 + 8x - 16 - x^2 + 4

= (3x^2 - x^2) + 8x - 16 + 4

= 2x^2 + 8x - 12

Answer:

Original expression:  [tex]3x^2+8x-16[/tex]

Let [tex]a[/tex] be the quantity Amir subtracted from the original expression.

Expression after subtraction: [tex]x^2-4[/tex]

[tex]\implies (3x^2+8x-16)-a=x^2-4[/tex]

Solve for [tex]a[/tex]:

[tex]\implies 3x^2+8x-16-a=x^2-4[/tex]

Add 4 to both sides:

[tex]\implies 3x^2+8x-12-a=x^2[/tex]

Subtract [tex]x^2[/tex] from both sides:

[tex]\implies 2x^2+8x-12-a=0[/tex]

Add [tex]a[/tex] to both sides:

[tex]\implies 2x^2+8x-12=a[/tex]

Therefore, Amir subtracted [tex]2x^2+8x-12[/tex] from the original expression.

Step-by-step explanation:

Work and answer shown above

The Domain is -4 ≤ x ≤ 2

Range = 2 ≤ y ≤ 6

We have given a graph of a function. We have to find the domain and the range of the function

The domain refers to the set of all valid input values for a function. It represents the values for which the function is defined or meaningful. In other words, it is the set of x-values that can be plugged into the function to obtain a corresponding y-value.

The range, on the other hand, refers to the set of all possible output values or y-values that result from evaluating the function with the input values from the domain. It represents the set of all values that the function can attain.

As we can see from the graph

value of x is greater than and equal -4 and less than and equals 2

Domain = -4 ≤ x ≤ 2

Value of y is grater than and equal to 2 and less than and equal to 6

Range = 2 ≤ y ≤ 6
