yea I'm not sure but maybe 40

Answer:

y = 2 and x = -3

Step-by-step explanation:

we know that opposite sides of a parallelogram are equal so

7y + 3 = 12y - 7

12y - 7y = 3 + 7

5y = 10

y = 10 / 5

y = 2

Now

-6x = -4x + 6

-6x + 4x = 6

-2x = 6

x = 6 / - 2

x = - 3

Hope it will help :)❤

Answer:

The circular pizza is cheaper because you pay less money for a unit area of the pizza

Step-by-step explanation:

Step one:

given data

The dimension of the square pizza is

24 X 24 cm

The area is

= 576cm^2

Also, the dimension of the circular pizza is

DIameter = 30cm

radius = 30/2 = 15cm

The area is

= πr^2

=3.142*15^2

=706.95cm^2

Step two:

let us find the cost per area of each of the shape of the pizzas

For the square pizza the cost per area is

= 7350/576

=$12.76 per area

For the circular pizza, the cost per area is

= 7350/706.95

=$10.40 per area

Answer: I believe the scale is balanced.

Step-by-step explanation: I stated that because since the other side of the scale contained 12 marbles that were 1 pound each that would be 12 pounds and then since 4+8=12 12 pounds of marbles were also put on the other side.

Answer:

The volume of water the pond will lose in 31 hours is 17.71 gallons.

Step-by-step explanation:

Given;

Rate of water leakage, R =  12 gallon of water in 23 hours

[tex]R = \frac{12 \ gallons}{23 \ hours}[/tex]

In 31 hours the volume of water leaked is calculated as;

[tex]V = \frac{12 \ gallons}{21 \ hours} \times 31 \ hours\\\\V = 17.71 \ gallons[/tex]

Therefore, the volume of water the pond will lose in 31 hours is 17.71 gallons.

Answer:

show trends clearly. that's the answer

Answer:

Step-by-step explanation:

since 105 + z is a straight line we know it equals 180 so we can use this equation

180 = 105 + z

simplify

75 = z

the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:

102 + 85 + 75

= 262

now subtract

360 - 262

= 98

y = 98

Answer:

Step 1: Calculate the change by subtracting old cost ($50) from the new cost ($64)

Step 2: Divide that change by the old cost ($50).  You will get a decimal number

Step 3: Convert the decimal number to a percentage by multiplying by 100%

Answer:

It sold 43.57 iPhones for the same quarter in the previous year.

Step-by-step explanation:

It sold 61.0 million iPhone, which is an increase of 40% over the value of the previous year x.

This can be interpreted as:

61 million is 140% = 1.4 of the previous year amount, that is, x. So

[tex]1.4x = 61[/tex]

[tex]x = \frac{61}{1.4}[/tex]

[tex]x = 43.57[/tex]

It sold 43.57 iPhones for the same quarter in the previous year.

Answer:

5

Step-by-step explanation:

you need to use the Pythagorean theorem

a^2+b^2=c^2

a&b=sides

c=hypotonuse

plug the side values into the equation

4^2+3^2=c^2

16+9=c^2

25=c^2

you have to square root 25 to find c itself

c=5

Answer : would be 5

Because a triangle that has a sequence of the number 3 & 4, or 3 & 5, or 4 & 5 will always consider of the number 3,4 and 5.

Also if te triangle did consist of different numbers the Pythagorean theorem ( a^2 + b^2 = c^2 ) can be use.

So in this case it’ll be 3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^ 2

Then we square root both sides and the answe will be : 5 = c

Answer:

f(x)=x^2+3x+2

Step-by-step explanation:

I believe the answer is 6.4 = 11.

Answer:

First, multiply the 5 by each of the terms inside the parentheses. Next, simplify each part of the expression and then add. The answer is 5(2+3)=25. The distributive property also works if there is subtraction inside the parentheses

Step-by-step explanation:

Answer:

20.92

Step-by-step explanation:

Given the data:

X : 170, 160, 130, 165, 125

Standard deviation (s) :

s = √Σ((X - m)² / n)

m = mean

n = sample size

Mean , m = Σx/n

m = (170 + 160 + 130 + 165 + 125) / 5

m = 750/5

m = 150

((X - m)² / n - 1)

[(170-150)^2 + (160-150)^2 + (130-150)^2 + (165-150)^2 + (125-150)^2] / (5-1)

= 1750 / 4

= 437.5

s = √437.5

s = 20.9165

s = 20.92

The x-intercept is Y-coordinate always zero which is the correct answer that would be an option (B).

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The x-intercept is defined as an intercept that is located at the x-axis of the plane, is the location or coordinate from where the line crosses

The general form of the linear equation, where m and b are constants, is written as y = mx + b. . As a result, the value of the y-coordinate in the corresponding linear equation will always be zero when it crosses the x-axis.

The y-coordinate for the x-intercept and the x-coordinate for the y-intercept are both zero. Another name for the x-intercept is the horizontal intercept.

Therefore, the x-intercept is Y-coordinate always zero which is the correct answer that would be an option (B).

Answer:

$10 coins: 21

$20 coins: 24

Step-by-step explanation:

So we can create 2 equations where

x = number of $10 coins

y = number of $20 coins:

x + y = 45

10x + 20y = 690

we can move equation 1 around so that we can get a value of x

x = 45 - y

now we can substitute x into the second equation

10(45 - y) + 20y = 690

450 - 10y + 20y = 690

10y = 240

y = 24

Now plug in y back into the first equation

x = 45 - y

x = 45 - 24

x = 21
