5(x+21)= 8x help me please
chubhunter [2.5K]

Answer:

35

Step-by-step explanation:

Steps

1.  5x + 105 = 8x because you distributed the 5

2. 105 = 3x because you subtract the 5x on both sides

3. 105/3 = x because you divide the 3 and 105/3 is 35

What is the value of x
Anika [276]

We know that the right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees.

<u>To find x:</u>

(10x - 20) + (6x + 8) =  180

16x - 12 = 180

      +12     +12

16x = 192

-----    -----

16        16

x = 12

<u>Check:</u>

(10(12) - 20) + (6(12) + 8) = 180

(120 -  20) + (72 + 8) = 180

100 + 80 = 180

180 = 180

<u>Angle (10x - 20):</u>

(10(12) - 20)

(120 - 20)

100

<u>Angle (6x + 8):</u>

(6(12) + 8)

(72 + 8)

80

\dfrac{3t-2}{t-1}=\dfrac{3(t-1)+1}{t-1}=3+\dfrac1{t-1}

\displaystyle\int\frac{3t-2}{t-1}\,\mathrm dt=3\int\mathrm dt+\int\frac{\mathrm dt}{t-1}=3t+\ln|t-1|+C
