Let <em>x</em> and <em>y</em> be the two numbers.

Their sum is 140, so

<em>x</em> + <em>y</em> = 140

Twice the first number <em>x</em> is 2<em>x</em>. 5 more than this is 2<em>x</em> + 5. This is the value of the second number, so

<em>y</em> = 2<em>x</em> + 5

Substitute this into the first equation and solve for <em>x</em> :

<em>x</em> + (2<em>x</em> + 5) = 140

3<em>x</em> + 5 = 140

3<em>x</em> = 135

<em>x</em> = 135/3 = 45

Then

<em>y</em> = 2*45 + 5 = 95

Alla [95]

Answer:

9240 feet

Step-by-step explanation:

Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile.

Step 1

The total distance Petrov ran in miles is calculated as:

1 lap = 1/4 mile

7 laps = x mile

Cross Multiply

x = 7 × 1/4 mile

x = 1.75 miles

Step 2

What is the total distance Petrov ran in feet?

1 mile = 5280 feet

1.75 miles = x

Cross Multiply

x = 1.75 × 5280 feet

x = 9240 feet

Therefore, the total distance Petrov ran in feet is 9240 feet

What is the line of SYMMETRY for they PARABLLA who’s equation is y=3x2+24x-1?
Arada [10]

Answer

The line of symmetry x = -4

Step by step explanation

Here we have to use the formula.

The symmetry of a parabola x = -b/2a

Now compare the given equation y = 3x^2 + 24x -1 with the general form y = ax^2 + bx + c and identify the value of "a" and "b"


Here a = 3 and b = 24. Now plug in these values in to the formula to find the line of symmetry.

x = -24/ 2(3)

x = -24/6

x = -4

Therefore, the line of symmetry x = -4.

Thank you.
