Answer:

x = -1/7

Step-by-step explanation:

First, combine like terms:

3 - 21x = 6

Then, isolate the variable:

-21x = 3

Then, divide -21 on both sides:

x = -3/21

Finally, simplify the fraction:

x = -1/7

Hope this helps!

What is the value of x in the equation 1/2x - 3/4 = 3/8 - 5/8

Kitty [74]

The answer

x = 1

step by step

$\frac{1}{2} x - \frac{3}{4} = \frac{3}{8} - \frac{5}{8} \\ \frac{1}{2} x = \frac{3}{8} - \frac{5}{8} + \frac{3}{4} \\ \frac{1}{2} x = \frac{3}{8} - \frac{5}{8} + \frac{6}{8} \\ \frac{1}{2}x = \frac{4}{8} \\ \frac{1}{2} x = \frac{1}{2} \\ x = 1$

If anyone knows this I will give them brainiest

statuscvo [17]

Answer:

x = 12

m(QS) = 52°

m(PD) = 152°

Step-by-step explanation:

Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)

Thus:

m<R = ½[m(PD) - m(QS)]

50° = ½[(12x + 8) - (4x + 4)] => substitution

Solve for x

Multiply both sides by 2

2*50 = (12x + 8) - (4x + 4)

100 = (12x + 8) - (4x + 4)

100 = 12x + 8 - 4x - 4 (distributive property)

Add like terms

100 = 8x + 4

100 - 4 = 8x

96 = 8x

96/8 = x

12 = x

x = 12

✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°

✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°
