Is -5 a solution to the equation for 6x + 5 = 5x + 8 + 2x? Explain?

Mathematics

For this case we have the following equation:

6x + 5 = 5x + 8 + 2x

We must find the solution.

We add similar terms from the right side of the equation:

6x + 5 = 7x + 8

We subtract 5 from both sides of the equation:

6x = 7x + 8-5\\6x = 7x + 3

We subtract 7x on both sides of the equation:

6x-7x = 3

Different signs are subtracted and the sign of the major is placed:

-x = 3

We multiply by -1 on both sides of the equation:x = -3

Thus, the solution of the equation is x = -3. -5 is not a solution to the equation.

Answer:

x = -3. -5 is not a solution to the equation

vazorg [7]

Answer:

If there is "p" pounds of peanuts and "m" pounds of '20% peanuts and 80% almonds' mixture, then, we can get the following equations,

p + m = 10 -----------(1) and

4m/5 = 4 ------------(2)

whose solution is 5 lb peanuts and 5 lb mixture.

Step-by-step explanation:

In the mixture which Delaney wants to make there would be

\frac {10 \times 60}{100} lb

= 6 lb of peanuts

So, there will be (10 - 6) lb  

= 4 lb of almonds

If  Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then according to the question,

p + m = 10 -----------(1) and

4m/5 = 4 ------------(2)

So, from (2),

m = 5 --------------(3)

So, from (1) and (3) ,

p = (10 - 5) = 5

What is the length of the shorter base of the Little Trapezoid trail?
valentina_108 [34]

Answer:

The length of the shorter base of the little trapezoid trail is 1 mi.

Step-by-step explanation:

Let the shorter base of the large trapezoid is S and the larger base of the large trapezoid is L.

Similarly, assume that the shorter base of the small trapezoid is s and the larger base of the small trapezoid is l.

Since, the trapezoids are similar, so

\frac{L}{l} = \frac{S}{s}

Now, given that S = 2 mi, L = 8 mi and l = 4 mi and we have to find s.

So, s = \frac{S \times l}{L} = \frac{4 \times 2}{8} = 1 mi. (Answer)
