How do you solve 21/4=1/2x+3x and whats the answer?

MissTica

Hi there!

To solve is pretty easy. First, simplify.

21/4=(1/2x+3x) -> Combine Like Terms
21/4=7/2x
FLIP
7/2x=21/4

Multiply both sides by 2/7.
(2/7)*(7/2x)=(2/7)*(21/4)
x = 2/3

Hope this helps!

Answer:

C. x = 1

Step-by-step explanation:

To solve this problem the best way is to use the quadratic formula. First make everything equal to 0 by adding 3 to both sides.

3x^2 - 6x + 3 = 0

The quadratic formula is: $\frac{-b\pm\sqrt{b^2-4ac} }{2a}$ . Substitute the values of a, b, and c into the formula. Keep in mind:

a = 3
b = -6
c = 3

$\frac{-(-6)\pm\sqrt{(-6)^2-4(3)(3)} }{2(3)} \rightarrow \frac{6\pm\sqrt{36-4(9)} }{6} \rightarrow \frac{6\pm\sqrt{0} }{6} \rightarrow \frac{1\pm0}{1} \rightarrow 1$

Therefore, x = 1.

Step-by-step explanation:

t^3 - 10t^2 + 33t - 36

3t^2 -20t + 33 = 0

(3t-11)(t-3) = 0

t = 3 or t=11/3

Seniors at a high school were asked what color car they drive. The results were put in a circle graph. The measure of each centr

horrorfan [7]

Answer:

P(The color of the car is red) is 0.32 .

P(The color of the car is white) is 0.34 .

P(The color of the car is silver) is 0.19 .

P(The color of the car is blue) is 0.15 .

P(car color is not red or blue) is 0.53 .

Step-by-step explanation:

We know that total angle subtended at the center by a complete circle is

360° .

According to the question,

P(The color of the car is red)

= $\frac {115.2}{360}$

= 0.32

P(The color of the car is white)

= $\frac {122.4}{360}$

= 0.34

P(The color of the car is silver)

= $\frac {68.4}{360}$

= 0.19

P(The color of the car is blue)

= $\frac {54}{360}$

= 0.15

So

P(car color is not red or blue)

= 1 - (0.15 + 0.32)

= 0.53
