Please help me <br>solve 3x+1/2=3/8+x​
gavmur [86]

Answer:

x= -\frac{1}{32}

Step-by-step explanation:

First move the x on the right side the the left side. Now your equation is

2x+\frac{1}{2}=\frac{3}{8} Next move 1/2 to the right side. Now your equation is 4x=\frac{-1}{8}. Next divide both sides by 4 to isolate "x." Now your equation is x= -\frac{1}{32}

Hope this helped and have a great day.

Answer:

4

Step-by-step explanation:

The sum of the measures of all interior angles in triangle is always equal to 180°. So,

∠A+∠B+∠C=180°

∠B=180°-63°-49°=68°

Now use the sine rule:

\dfrac{c}{\sin \angle C}=\dfrac{b}{\sin \angle B}\\ \\\dfrac{3}{\sin 49^{\circ}}=\dfrac{b}{\sin 68^{\circ}}\\ \\b=\dfrac{3\sin 68^{\circ}}{\sin 49^{\circ}}\approx 3.685\approx 4

adjacent = 30

sineoko [7]

Answer:

The mean is 70.8.

Finding the arithmetic mean, or average, can be found by adding up all the numbers divided by the total count of those numbers.

So, we have :: 60, 67, 71, 76, 80.

These numbers added together = 354.

There are 5 numbers listed.

354 / 5 = 70.8.
