Solve for x 8x—3=5 (2x+1

vagabundo [1.1K]

Answer:

x=-4

Step-by-step explanation:

1. Expand.

8x-3=10x+5

2. Subtract 8x8x from both sides.

-3=10x+5-8x

3. Simplify 10x+5-8x to 2x+5.

-3=2x+5

4. Subtract 5 from both sides.

-3-5=2x

5. Simplify -3-5 to -8.

-8=2x

6. Divide both sides by 2.

-8/2 =x

7. Simplify 8/2 to 4

-4=x

8. Switch sides.

x=-4

4(x−0.8)=3.8x−5.8 PLZZZ ANSWER FAST!

Hunter-Best [27]

To find the answer:
$4(x - 0.8) = 3.8x - 5.8 \\ 4x - 3.2 = 3.8x - 5.8 \\ 4x - 3.8x = - 5.8 + 3.2 \\ 0.2x = - 2.6 \\ x = - \frac{ 2.6}{0.2} \\ x = - 13$

Therefore, x=-13.

Hope it helps!

Find the equation of the ellipse with the following properties.

zmey [24]

Answer:

The equation of ellipse is $\frac{x^2}{25}+\frac{y^2}{9}=1$ .

Step-by-step explanation:

The center of ellipse is origin because the ellipse has foci at (4, 0) and (-4, 0); y-intercepts (0, 3) and (0, -3).

The general equation of an ellipse is

$\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$

Where, a is major axis and b is minor.

The y-intercepts are (0, 3) and (0, -3). So, the value of b is 3.

The foci of ellipse is $(\pm c,0)$ .The relation between foci and major, minor axis is

$c^2=a^2-b^2$

$(4)^2=a^2-(3)^2$

$16=a^2-9$

$a^2=25$

$a=5$

The equation of ellipse is

$\frac{x^2}{5^2}+\frac{y^2}{3^2}=1$

$\frac{x^2}{25}+\frac{y^2}{9}=1$

The sum of 5% of a number and 9 is 16

netineya [11]

Ok, so first find out what the number actually will be

16 - 9 = 7

So you need to find out the complete number. You can do that by dividing

7 / 5% = 120

So that means the sum of 5% of 120 and 9 is 16.
