5 frisbees and 3 volleyballs cost $36 the cost of 2 frisbees and 7 volleyballs is $18 which of the following systems could be used to calculate the cost of one frisbee and one volleyball​

Answer:

Step-by-step explanation:

First you have to multiply both sides by 4

4 (3x - 1)  by 4 > 3 x 4

Then simplify it:

3x-1 > 12

Now add one to both sides

3x - 1 + 1 > 12 + 1

Then simplify it again:

3x > 13

Now divide both sides by 3

3x ÷ 3 >  13 ÷ 3

Answer:

x = 13 ÷ 3

Answer:

The third side has a length of 4x² + x - 16

Step-by-step explanation:

We can solve this by taking the value given for the perimeter, and subtracting the values of the other two sides:

3x² + 8x - 9 - (x² + 11x + 5) - (-2x² - 4x + 2)

= 3x² + 8x - 9 - x² - 11x - 5 + 2x² + 4x - 2

= (3 - 1 + 2)x² + (8 - 11 + 4)x - (9 + 5 + 2)

= 4x² + x - 16

Answer:

3a) 5/45 you divide by 5

3b) 6/7 you divide by 2

3c) 2/7 you divide by 9

3d) 2/5 you divide by 9

4a) 6

4b) 1 1/4 or 5/4 (both are correct)

4c) 3 1/2 or 3 3/6 (both are correct)

4d) 5 1/8

The fraction bar tells you to divide the top number by the bottom number.

Step-by-step explanation:

For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.

For 4a through 4b, devide the top the bottom number

Answer:

Incorrect

Step-by-step explanation:

The formula for slope is [ y2-y2/x2-x1 ] and Emma calculated the slope using the opposite of the formula [ x2-x1/y2-y1 ]. That was her mistake.

Answer: See explanation

Step-by-step explanation:

ΔLNM and ΔLKN are 30°- 60°- 90° triangles

We have to find the length of LN before we can find the length of MN.

In a 30°- 60°- 90° triangle, the length of the hypotenuse is 2 times the length of the shorter leg, and the length of the longer leg is the length of the shorter leg times √3

Since the hypotenuse is 6, the short leg would be 3 since the hypotenuse is 2 times the length of the short leg.

LN = √3 times the shorter leg

3 × √3 = 3√3

LN = 3√3

We now know the length of the longer leg in ΔLNM (3√3)

MN would be 3√3 × √3

3√3 × √3

= 3√9

= 3 × 3 = 9

MN = 9

ΔLKM is also a 30° - 60° - 90° triangle

The short leg is 6 m

The hypotenuse would be 12 m

The longer leg would be 6√3

Perimeter: 6 + 12 + 6√3

The perimeter is 18 + 6√3

Area: 1/2 × b × h

b = 6√3

h = LN = 3√3

6√3 × 3√3

18√9 = 18 × 3 = 54

Area: 54 m²

Answer:

See the attached picture.

Step-by-step explanation:

I had to look up 'balanced hanger' because that was not a term from my own math education, but I found it no problem.

See the attached picture.

There are 2 x's on the left and 4 1's on the right.

This means the equation has 2 x's on the left of the equal sign and 4 1's on the right.

Each unit of different size should be in a different shape.

The idea is that the hanger 'balances', just like a set of scales, or the same way an equation balances both sides.

Hope this helps.

Answer:

7.5

Step-by-step explanation:

The ratio between the two numbers in each set are the same, so the process used to get from 4 to 6 could also be used to find x. 6/4=1.5, so 4*1.5=6. Multiplying 5 by 1.5 would get x. 5*1.5=7.5, so x=7.5.

Answer:

[tex]\huge\boxed{3\cdot10^8\dfrac{m}{s}=1.08\cdot10^9\dfrac{km}{h}}[/tex]

Step-by-step explanation:

[tex]3\cdot10^8\dfrac{m}{s}\\\\1km=1,000m\to1m=0.001km\\1h=3,600s\to1s=\dfrac{1}{3600}h[/tex]

therefore

[tex]3\cdot10^8\dfrac{m}{s}=3\cdot100,000,000\cdot\dfrac{\frac{1}{1000}km}{\frac{1}{3600}s}=300,000,000\cdot\dfrac{1}{1000}\cdot\dfrac{3600}{1}\dfrac{km}{h}\\\\=\dfrac{300,000,000\cdot3,600}{1,000}\dfrac{km}{h}=300,000\cdot3,600\dfrac{km}{h}=1,080,000,000\dfrac{km}{h}\\\\=1.08\cdot10^9\dfrac{km}{h}[/tex]

Answer:

The relation is [tex]y = -1.5x[/tex]

Step-by-step explanation:

x and y are directly proportional:

This means that the equation is given by:

[tex]y = ax[/tex]

In which a is the multiplier that relates these two variables.

x= -4, y =6

We use this to find a. So

[tex]y = ax[/tex]

[tex]6 = -4a[/tex]

[tex]a = -frac{6}{4}[/tex]

[tex]a = -1.5[/tex]

So

The relation is [tex]y = -1.5x[/tex]

The larger number is 301804

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

The smaller number =6 524,

The difference between two numbers = 308 328

Now,

Let the missing number be x

x-6524=308328

x=308328-6524

x=301804

Therefore, the larger number of algebra will be 301804.

Step-by-step explanation:

Answer:

The value of the parameter of interest in this setting is:

d. The value of the parameter of interest cannot be determined from the given information.

Step-by-step explanation:

To determine the parameter of interest in this setting, we need information about the population figure of the small-to-medium-sized streams in eastern North Carolina.  We also require the population proportion of these streams, which have runoff from hog farms.  But in this situation, the information is lacking.  Instead, we are given information about the sample, which only produces statistics.  For example, we can calculate the average (mean) proportion of the sample of 242 small-to-medium-sized streams using the 55 that were found to have runoff from hog farms.

Hope this helps! :)

Answer:  B.  (5,11)

Step-by-step explanation:

c  = 6 + 1s          In this case we know that c is your total cost and s is the number of downloaded songs.

If we were to do it in terms of x and y, y will be c, and x will be s.

Now is asking for the cost of 5 songs, so you will input the value 5 into the equation for s and solve for c.

c = 6 + 1(5)

c = 6 + 5

c = 11

Now we know that for 5 songs it will cost you $11, and if x is the same as the number of songs, and y is the total cost then we can say that the point will be,

[tex] m\angle O = 134 \degree[/tex]

Step-by-step explanation:

AC and AB are tangents to the circle with center O on points C and B respectively from point A.

Therefore

[tex] m\angle ACO=m\angle ABO=90\degree [/tex]

[tex] m\angle CAB=46...(given) \degree [/tex]

[tex]m\angle O = 360 \degree - (2 \times 90 \degree + 46 \degree) \\ \\ m\angle O = 360 \degree - (180 \degree + 46 \degree) \\ \\ m\angle O = 360 \degree - (226 \degree) \\ \\ m\angle O = 134 \degree\\ \\ [/tex]

Answer:

b

Step-by-step explanation:

Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.

6x - 5y = 17

7x + 3y = 11

Using elimination method

18x - 15y = 51

35x + 15y = 55

18x + 35x = 51 + 55

53x = 106

x = 106/53

x = 2

6x - 5y = 17

6(2) - 5y = 17

12 - 5y = 17

-5y = 17 - 12

-5y = 5

y = 5/-5

y = -1

Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1
