I need help plzzzzzzz help24+4x=6x+2

Answer:

 [1]    x - y = -10

  [2]    2x + 4y = 22

Step-by-step explanation:

// Solve equation [1] for the variable  x  

 [1]    x = y - 10

// Plug this in for variable  x  in equation [2]

  [2]    2•(y -10) + 4y = 22

  [2]    6y = 42

// Solve equation [2] for the variable  y  

  [2]    6y = 42  

  [2]    y = 7  

// By now we know this much :

   x = y-10

   y = 7

// Use the  y  value to solve for  x  

   x = (7)-10 = -3

I am sorry if I got it wrong but I hope this helped.

Answer:

Trevor has 30 more cents than Jeff.

Step-by-step explanation:

Jeff:

1 dime = 10 cents.

So we do 10x7=70.

So Jeff has 70 cents.

Trevor:

1 nickel = 5 cents

So we do 20x5 = 100 cents which is the same thing as 1 dollar.

Then we do 100 cents - 70 cents which is 30 cents.

Answer:

she earned a total of 1190 in 5 years. I don't know if this helps.

Step-by-step explanation:

The rate of interest with the given parameters is 6.8%.

Given that, Principal =$3,500, time period =5 years and the amount =$4,690.

We need to find the rate of interest.

The interest rate formula helps in calculating the amount of money to be repaid towards a loan taken and the interest over the investment on fixed deposits, mutual funds, etc. The interest rate formula also helps in calculating the interest on credit cards. The interest rate for a given amount on simple interest can be calculated by the following formula,

Interest Rate = (Simple Interest × 100)/(Principal × Time)

Now, SI=Amount-Principal=4690-3500=1,190

rate of interest=(1,190×100)/(3,500×5)=6.8%

Therefore, the rate of interest with the given parameters is 6.8%.

Answer:

n = 78

Step-by-step explanation:

IQR is the interquartile range of the data set.

So Saul had already arranged the data in order, that is the first step when calculating the interquartile range.

25, 30, 50, 50, 50, 50, 56, n., 250

Next, is to find the median so we could easily separate the data into quartiles.

The median of the data 25, 30, 50, 50, 50, 50, 56, n., 250 = 50

Then, arrange the data into the first quartile and the third quartile

first quartile = 25, 30, 50, 50

third quartile = 50, 56, n., 250

first quartile median = 30 + 50 = 80/2 = 40

third quartile = 56 + n /2

The interquartile range formula is the first quartile subtracted from the third quartile:

IQR = Q3 – Q1.

Since 27 is the interquartile range, n=

27 = (56 + n /2) - 40

Use 2 to multiply through to eliminate the denominator

54 = (56 + n) - 80

n = 78

Answer: 166 cm

Step-by-step explanation:

x / 19 = 126

* 19 * 19

x = 2394

(2394 + y) / 20 = 128

* 20 * 20

2394 + y = 2560

- 2394 - 2394

y = 166

Answer:

D)16

Step-by-step explanation

we are given a 30-60-90 triangle and the longer side of the triangle

remember the properties of 30-60-90 triangle

as we are given the longer leg we'll use the second property

let the shorter leg be x

so our equation is

[tex]\displaystyle x\sqrt{3}=16\sqrt{3}[/tex]

divide both sides by √3:

[tex]\displaystyle \frac{x\sqrt{3}}{\sqrt{3}}=\frac{16\sqrt{3}}{\sqrt{3}}[/tex]

[tex]\displaystyle x=16[/tex]

hence,

the length of the shorter leg is 16
