The value of x is \mathbf{8\dfrac{1}{3}}

The objective of this question is to evaluate and determine the value of x. The fraction given in the question consists of algebraic expressions and, we need to solve it through following process;

∴

\mathbf{\dfrac{x-1}{3-x} + \dfrac{3}{4}=-1 }

Collect like terms

\mathbf{(\dfrac{x-1}{3-x})=-1 -\dfrac{3}{4}}}

\mathbf{(\dfrac{x-1}{3-x})=-(\dfrac{7}{4}})}

-4(x - 1) = -7(3 -x)

-4x + 4 = -21 + 7x

4x -7x = -21 - 4

-3x = - 25

\mathbf{x= \dfrac{25}{3}}

\mathbf{x= 8\dfrac{1}{3}}

What is the length of JM in the given figure?
umka21 [38]

Answer:  B. 30

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

When given a secant and a tangent, the formula is:

exterior of secant × secant = tangent²

                     KM   ×    JK     =    LK²

                      10   ×  (JM + 10) = 20²

                            10JM + 100 = 400

                                     10JM = 300

                                         JM =  30

Help solve for r algebra
bija089 [108]

Answer:

\frac{20}{7}

Step-by-step explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

7r=4(5)

Simplify: 7r=20

Divide both sides of the equation by 7 to get: r=\frac{20}{7}

1/5x + 4 =1/3x-8 <br> Can you show your work too? That would be great
Vikentia [17]

Answer:

90

Step-by-step explanation:

1/5x+4=1/3x-8

add 8 to both sides and subtract 1/5x from both sides

4+8=1/3x-1/5x

12=5/15x-3/15x

12=2/15x

divide both sides by 2/15

12÷2/15=x

when dividing by a fraction, invert and multiply

12*15/2=x

90=x

CHECK:

1/5(90)+4=1/3(90)-8

18+4=30-8

22=22
