Answers

Answer:

x= 3/4

Step-by-step explanation:

[tex](3x - 2) = \frac{(2x-1)}{2}[/tex]

2(3x - 2) = (2x - 1)

6x - 4 = 2x -1

4x = 3

x= 3/4

Answer:

x=3/4

Step-by-step explanation:

Remove parentheses.

3x-2=\frac{2x-1}{2}3x−2=22x−1

Multiply both sides by 22.

6x-4=2x-16x−4=2x−1

Add 44 to both sides.

6x=2x-1+46x=2x−1+4

Simplify 2x-1+42x−1+4 to 2x+32x+3.

6x=2x+36x=2x+3

Subtract 2x2x from both sides.

6x-2x=36x−2x=3

Simplify 6x-2x6x−2x to 4x4x.

4x=34x=3

Divide both sides by 44.

x=\frac{3}{4}x=43

Answers

Answer:

√35i

Step-by-step explanation:

i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.

Answer:

We know that √-1 = i, where "i" is the imaginary unit

± √(-35) = ± √(35) i

± √(35) i is the right answer.

7 blue socks and 6, 5, 8 of non-blue socks. If you add the numbers of non-blue socks you get 19. Blue socks to non-blue would be 7:19

Answer:

The ratio is 7 to 19 or 7:19

Step-by-step explanation:

Since there are 7 blue socks and other colors are not blue we add the number of other colors. So basically 8+5+6= 19 and then 7 blue socks :)

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car used 25 liters on a 100 km trip at 100kph,about how many liters will it use on 1000 km trip at 64 kph?

Answers

Answer:

200 litres

Step-by-step explanation:

let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is

g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation

To find k use g = 25, d = 100 and s = 100, then

25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )

0.025 = k

g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation

When d = 1000 and s = 64, then

g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200

What equation represents the slope intercept form of the line below Y intercept =(0,-2) slope = 2/3

Answers

Answer: [tex]y = \frac{2}{3} x - 2[/tex]

Step-by-step explanation:

The slope intercept form is y = mx + b

Where m is our slope and b is our y-intercept

We're given a slope of 2/3

We're given a y-intercept of -2

Substituting into y = mx + b gives

[tex]y = \frac{2}{3} x - 2[/tex]

Answer:

y = (2/3)x - 2

Step-by-step explanation:

Use the slope-intercept form y = mx + b. Here b = -2 and m = 2/3. Making these replacements, we get:

y = (2/3)x - 2
