Answer:

Step-by-step explanation:

the student buys a total of 8 magazines for $14.00

x+y = 8

x = 8-y

2x+1.6y = 14

2(8-y)+1.6y = 14

16-2y+1.6y = 14

16-0.4y = 14

0.4y =16-14 = 2

y = 2/0.4 = 5

x = 8-y = 3

The correct equation best represents the situation is,

⇒ x + y = 8

And, 2x + 1.60y = 14.00

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A student buys (x) fashion magazines and (y) sports magazines.

And, Each fashion magazine costs $2.00 and each sports magazine costs $1.60.

Here, The student buys a total of 8 magazines for $14.00.

Hence, We can formulate;

⇒ x + y = 8

And, 2x + 1.60y = 14.00

Thus, The correct equation best represents the situation is,

⇒ x + y = 8

And, 2x + 1.60y = 14.00

Answer:

49π ft²

Step-by-step explanation:

The area for a circle is A=πr² (Area=pi times radius squared)

and d=2r (diameter = 2 times the radius)

So, if we want to find area using the radius, we can get rearrange the equation d=2r to get r= d/2

r=d/2

r=14/2

r=7 ft

Then we can plug that answer into the area equation.

A=π×7²

7 squared is 49 so

A=49π ft²

The 7th term is 0

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because every term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)d[/tex]

Where

an = nth term

a1 = first term

d   = common difference

n  = number of the term

We are given the first term a1=-12 and the common difference d=2. Let's find the 7th term (n=7):

[tex]a_7=-12+(7-1)2[/tex]

[tex]a_7=-12+12=0[/tex]

The 7th term is 0

Answer:

-8,4 and 4,-5

Step-by-step explanation:

Answer:

u can use "a squared + b squared = c squared"

in this case the two legs are 10 and 24 because they are near the right angle. the hypotenuse is always across from the right angle, so it's the long side that connects the two legs. Now you can plug in 10 and 24 for the pythagorean theorem and solve for the hypotenuse. that would be 10 squared plus 24 squared equal to c squared.

Answer:

26

Step-by-step explanation:

You would use the Pythagorean theorem to solve for the last side.

Pythagorean theorem- a^2+b^2=c^2

a and b =sides

c=hypotenuse

Since you are finding the hypotenuse(c), you don't have to rearrange the formula

plug in a and b.

10^2+24^2=c^2

solve

100+576=c^2

676=c^2

do the square root of 676 to get rid of the c^2

26=c

Answer:

p=500

Step-by-step explanation:

The value of p is 500 in the equation  100+0.05p=0.25p.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

The equation,

100+0.05p=0.25p

To solve the equation:

Simplify the equation,

100 = 0.25p - 0.05p

0.20p = 100

p = 100/0.20

p = 500

Therefore, 500 is the value of p.

Answer:

11/9

Step-by-step explanation:

5/9 + 4/6 = 11/9

Answer:  sixty six fifty fourths  

30/54 + 36/54 = 66/54

Step-by-step explanation: Find a common denominator

Here, it looks like we can multiply the 9 × 6 to get 54

Then we divide the original denominator into the common denominator, then multiply the numerator by the quotient to get an equivalent fraction to add.

Starting with the 5/9   54÷9 = 6   The quotient, 6 multiplies by the numerator 5

6 × 5 = 30  That is the new numerator.

30/54 is the equivalent fraction for 5/9

Now 4/6   54÷6 = 9   Multiply this quotient, 9 times the numerator 4

9 × 4 = 36  That is the new numerator

36/54 is the equivalent fraction for 4/6

Add the numerators of the equivalent fractions keep the denominator the same:

30/54 + 36/54 = 66/54

It is possible to simplify this process. 4/6 is equivalent to 2/3 or 6/9

We could add  5/9 + 6/9 to get 11/9

66 and 54 are both divisible by 6, so 66/54 can be simplified to 11/9 or the mixed number 1²/₉

Answer:

[tex]0.10d + 0.25q > 143.88[/tex]

Step-by-step explanation:

Let the total dimes collected be d.

[tex]1\ dime = \$0.10[/tex]

[tex]d\ dimes = \$0.10d[/tex]

Let the total quarters collected be q.

[tex]1\ quarter = \$0.25[/tex]

[tex]q\ quarters = \$0.25q[/tex]

[tex]Last\ Year = \$143.88[/tex]

Required

Represent as an inequality

The total collection, this year, can be represented as:

[tex]Total = 0.10d + 0.25q[/tex]

From the question, we understand that:

This year's collections is expected to be greater than last year's

This can be represented as:

[tex]Total > Last\ Year[/tex]

Substitute in the right values:

[tex]0.10d + 0.25q > 143.88[/tex]
