Let the first number be x, and the second 5x. The second is five times the first, so thats why it is 5x. Now, add x+5x=50. Simplify the equation to be 6x=50, because x+5x is 6x. Do the opposite of multiplyig because 6x is the same as 6 times x. Divide 6 on both sides. 50 divided by six is your first number (x). Now multiply your quotient by 5 to find the second number, and those are your two numbers.

Let the first and smaller number be x. Since the second number is 5 times the first, the second number is 5x. We also know both of these numbers must add to 50; thus, we can create the following equation.

x+5x=50

Combine like terms

6x = 50

Divide both sides by 6

x = 50/6 = 25/3 \approx 8.333

This is the value of the first number. The number you're looking for isn't specified in the question description, so I'll just provide the value of the second number. The second number has to be 5 times the first.

Thus, we just multiply 5 to x.

5x = 5(25/3) = 125/3 \approx 41.667

That's the value of the second number.

Solve the system of equations.<br> 7y + 10.x = -11<br> 4y - 3x = -15
Sidana [21]

Answer:

x= 1

y= -3

Step-by-step explanation:

multiply them to get common factor for y or x:

3(7y+10x=-11)

10(4y-3x=-15)

21y+30x=-33

40y-30x=-150    <em>x's cancel out so solve for y</em>

61y = -183

/61      /61

y = -3                 <em> insert y into either equation and solve for x</em>

<em />

<em>4(-3) -3x=-15</em>

<em>x = 1</em>

Blank * 1/4 is equal to 2
Montano1993 [528]

8, that is the same as saying what divided by 4 is 2, and 8 divided by 4 is 2. Thus, 2 is 1/4th of 8.

5 divided by 485 3 digit by 1 digit
victus00 [196]

Answer:

  5\div485=\dfrac{5}{485}=\dfrac{1}{97}\\\\485\div 5=\dfrac{485}{5}=97

Step-by-step explanation:

When we say "a divided by b", we mean a/b. In this case, "5 divided by 485" is a 1-digit number divided by a 3-digit number. The result is the fraction 1/97 or a repeating decimal with a long repeat.

If you want to divide the 3-digit number 485 by the 1 digit number 5, then you need to formulate the problem as "485 divided by 5". The result is 97.

Please explain this step by step and solve within 10-20 minutes please
DaniilM [7]

Answer:

y=\frac{306}{7} is the answer.

In decimal y = 43.71

Step-by-step explanation:

Given:

y varies directly with x .

Also x = 7 when y = 18

To Find:

y = ? when x = 17

Solution:

y varies directly with x .

i.e. y is directly proportional to x

∴ y = k\times x

Where

k = constant of proportionality {Remain Same}

First we will find constant of proportionality k,

∴ When x = 7 and y = 18 we have

∴ 18 = k\times 7\\\\k=\frac{18}{7}

Now when x= 17 and k=\frac{18}{7} we have

∴ y = k\times x

∴ y=\frac{18}{7}\times 17\\\\y=\frac{306}{7}\\\\ y=43.71
