8x/10x-2 equals 5x+3/7x solve for x

Mathematics
1 answer:
Andrews [41]2 years ago
4 0

<u>Answer:</u>

x = \frac{1}{3} & 3

<u>Step-by-step explanation:</u>

\frac{8x}{10x-2} = \frac{5x+3}{7x}

Cross multiply:

\frac{8x}{10x-2} = \frac{5x+3}{7x}   ⇒   (8x)(7x) = (5x+3)(10x-2)

Simplify both sides:

(8x)(7x) = (5x+3)(10x-2)   ⇒   56x² = 50x²+20x-6

Set equation equal to 0:

56x² = 50x²+20x-6   ⇒   0 = -6x²+20x-6

Factor the trinomial:

0 = -6x²+20x-6 = (-6x+2)(x-3)

Solve for X:

-6x+2 = 0

-6x = -2

x = \frac{1}{3};

x-3 = 0

x = 3;

x = \frac{1}{3}, 3

When translating the phrase "twice the quantity of four more than three times a number"on students wrote the expression 2*3x+4
kozerog [31]
It is wrong because the equation is missing parentheses around the sum

When it says "the quantity of..." it always means parentheses. The correct equation is 2(3x+4)

Can anyone help me please
Sauron [17]

Range of values of x is 25°<x<27°.

<u>Step-by-step explanation:</u>

An angle is formed when two rays, a line with one endpoint, meet at one point called a vertex.Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. The Alternate Interior Angles theorem states, if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

In above question, sides are equal and so alternate interior angles are equal i.e. 2x + 10° = 62° ⇒ 2x = 52° ⇒ x =26°

∴ range of values of x is 25°<x<27°

is x-1 taking away an x or adding an x?? im trying to find the perimeter of area tiles, and the perimeter is x + x + x + (x-1) +
Vanyuwa [196]

Answer:

4x + 2

Step-by-step explanation:

x - 1 is adding an x and subtracting a 1 ,so

x + x + x + (x - 1) + 1 + 1 + 1

= x + x + x + x - 1 + 1 + 1 + 1 ← collect like terms

= 4x + 2
