Answer:

3/2^3=3/8 and (-1/4)^2 = 1/16

Step-by-step explanation:

1. You know what 2^3 is, right? That's 2*2*2. 2*2 is 4, and then 4*2 is 8. So that is 3/8.

2. (-1/4)^2 is (-1/4)*(-1/4), right? So that is (-1*-1)/(4*4). Two negatives make a positive, so -1*-1=1. 4*4 is 16, so we have 1/16.

The expression can be used to determine how much more money Club A will cost than Club B after x months is 7 - 4x

A linear equation is in the form:

y = mx + b;

where y, x are variables,  m is the rate of change and b is the initial value of y.

Let y represent the total cost for x months.

Club A charges a $35 joining fee, plus $19 per month. hence:

y = 19x + 35

Club B charges a $28 joining fee, plus $23 per month. hence:

y = 23x + 28

Club A will cost than Club B:

19x + 35 - (23x + 28)

= 7 - 4x

The expression can be used to determine how much more money Club A will cost than Club B after x months is 7 - 4x

Answer:

Perimeter: 14 9/10 cm

Area: 11 7/10 cm^2

Step-by-step explanation:

First, you must find the perimeter of the rectangle. The definition of perimeter in terms of mathematics are: the continuous line forming the boundary of a closed geometric figure. To find the perimeter of any shape, you must add up all the sides. Thus:

2 1/4 + 2 1/4 + 5 1/5 + 5 1/5 = ?

To put it simpler -

2(2 1/4 + 5 1/5) =

4 5/10 + 10 4/10 =

14 9/10 cm

Then, you must find the area of the rectangle. The definition of the area are: the extent or measurement of a surface or piece of land. In other words, the amount of space an object takes up. You must multiply the length and width of the rectangle to find the area.

Formula of area:

A = L x W

A = 2 1/4 x 5 1/5

A = 9/4 x 26/5

A = 234/20

A= 11 7/10 cm^2

To sum it up, the perimeter of the rectangle is 14 9/10 cm and the area 11 7/10 cm^2.

Answer:

Step-by-step explanation:

A relation is only a function if ALL the x-values (the first number in the pairs) ONLY have one partner.

Check that -1

At first that -1 is paired up with a 5 in the ordered pair (-1, 5) but then later... that -1 is down there hanging out with a 1 in the last ordered pair (-1, 1).

This means that this relation (all the pairs lumped together) is NOT a function. Just because of that -1 pairing up with more that one partner.

5

she gave her sister 5 toys.

Correction to the question - It is not 15 it 1/5th.

According to the given question Cynthia had 25 toys and she gave 1/5th of her toys to her little sister.

So, The total number of toys is 25 to find 1/5th of it we need to multiply the total number of toys she had and the fraction she gave.

(25 x 1/5) = 5. so the number of toys she gave away to her little sister is 5.

Answer:

The greatest common factor of 70 and 15 is 5.

Step-by-step explanation:

First, list the prime factors for each individual number

Next, circle each common prime factor. This means that you must find the prime factors that are the same as each other. For example, if it's 1 3 4 and 2 3 5, the common prime factor would be 3.

Finally, you must multiply all of the common prime factors. Your answer will be the greatest common factor!

So, the greatest common factor of 70 and 15 is 5.

Answer: 39

(3*(19))-18 = 39

57-18 = 39 we have the correct answer

The value of x in the equation is 364/145

The equation is given as:

[tex]\frac 32x - 5= -\frac 47x + \frac 15[/tex]

Collect the like terms

[tex]\frac 32x + \frac 47x= 5 + \frac 15[/tex]

Take the LCM

[tex]\frac{21x + 8x}{14} = \frac{25 + 1}{5}[/tex]

Evaluate the sum

[tex]\frac{29x}{14} = \frac{26}{5}[/tex]

Cross multiply

[tex]145x = 364[/tex]

Divide both sides by 145

[tex]x = \frac{364}{145}[/tex]

Hence, the value of x in the equation is 364/145

The weight of Euclid is 10.625 pounds, and the weight of Riemann is 21.25 pounds.

The expression that represents the given scenario is written as;

when Pythagoras weight is 1/4 pound less than weight in January:

T + 1.2x + 0.25 = y

y- 13 + 1.2x + 0.25 = y

1.2x - 12.75 = 0

Euclid's weight is calculated as follows;

1.2x = 12.75

[tex]x = \frac{12.75}{1.2} \\\\x = 10.625 \ pounds[/tex]

The weight of Riemann is calculated as follows;

[tex]= 2 (10.625)\\\\= 21.25 \ pounds[/tex]

Given: JK = 3x - 5, KL = 2x + 1

The sum of the segments JK and KL will equal the length of the segment JL = 16

So we can write:

3x - 5 + (2x + 1) = 16 [JK + KL = JL]

Collect terms, solve for x:

5x - 4 = 16

5x = 20

x = 4

JK = 3x - 5 = 3*4 - 5 = 12 - 5 = 7
