Determine if the following equation has "One Solution", "No Solutions", or "Infinite Many Solutions".

Novosadov [1.4K]

First, distribute the 2.
2x+6=6+2x
These are the same, so therefore it is infinitely many, because whatever you plug in for x will work.

8 of the 12 students on a soccer team are on the honor roll. if the relationship on this team is proportional to the number of h

Mrrafil [7]

Answer:

267 students

Step-by-step explanation:

Number of students in a team (t) is proportional to number of honor roll students (n)

Mathematically, t = kn (k is constant

When t = 12, n = 8

k = t/n = 12/8 = 1.5

When t = 400

n = t/k = 400/1.5 = 267 (to the nearest whole number)

Solve for x<br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%20-%202%7D%20%20%3D%200" id="TexFormula1" title=" \sqrt{x - 2}

Firdavs [7]

To solve for x, you need to isolate/get x by itself in the equation:

$\sqrt{x-2} =0$ Square ² both sides to get rid of the square root √

$(\sqrt{x-2} )^2=(0)^2$

x - 2 = 0 Add 2 on both sides

x - 2 + 2 = 0 + 2

x = 2

Jonah drives from his car to and from work. The total length of the trip to and from work is 19.2 miles. In August, Jonah worked

natita [175]

ANSWER

The total length of the trip to and from work in August is

$403.2 \: miles$

EXPLANATION

The total length of the trip to and from work is

$19.2 \: miles$

If Jonah worked 21 days in August,

Then, the total length of the trip to and from work is
$= 21 \times 19.2 \: miles$

Change the decimal to fraction and multiply,

$= 21 \times \frac{192}{10} miles$

$= \frac{21 \times 192}{10}$

$= \frac{4032}{10} miles$

Convert back to decimal

$= 403.2 \: miles$
