How to solve 2x-1/2=3-x

Mathematics
1 answer:
ValentinkaMS [17]3 years ago
5 0
To solve for x:
Move all the terms containing "x" to the left side of the equation. Do this by adding x to both sides.

2x+x=3x. The new equation is:
3x-1/2=3

Now, move all terms not containing "x" to the right side of the equation. Do this by adding 1/2 to both sides.
3x=3+1/2 The new equation is:
3x=3 1/2, or 3.5

The final step is to isolate x. To do so, divide each side by 3.
3x/3 = 3 1/2 /3 The new equation is:
x=1 1/6

Figure ABCD is a kite. The area of ABCD is 48 square units. The length of line segment BD is 8 units. What is the length of AC?
Fed [463]

A = d1 x d2 / 2

d1 = BD = 8 units

48 = 8 x AC / 2

48 x 2 = 8 AC

96 = 8 AC

AC = 96 : 8 = 12

Answer: D ) 12 units

3 Simple Questions! Help! 99 Points! Brainliest!
WARRIOR [948]

Answer:

1.       ridescost+admission=total

if x=number of tickets and y is total and cost per ride is 1.25 then

1.25x+admission=y

if we solve

when x=25, y=43.75

1.25(25)+admission=43.75

31.25+admission=43.75

minus 31.25 from both sides

admission=12.50

a.

y=1.25x+12.5

b.

x is number of tickets and y is total cost

c. math, seriously, just read what is above option a (the one in the top of the answer)

if you're too lazy then:

ridescost+admission=total

if x=number of tickets and y is total and cost per ride is 1.25 then

1.25x+admission=y

if we solve

when x=25, y=43.75


2.    

(a)  

m = (y2 - y1) / (x2 - x1) = (4 - 9)/(-2 - 8) = -5/(-10) = 1/2  

(b)  

y - y1 = m(x - x1)  

Using the first given point,  

y - 9 = (1/2)(x - 8)  

Using the second given point,

y - 4 = (1/2)(x + 2)

note they both simplify to  

y = (1/2)x + 5  

(c)  

y = (1/2)x + 5

Using De-Moivre's theorem, prove that i^2= -1.​
Novosadov [1.4K]

Write i in trigonometric form. Since |i| = 1 and arg(i) = π/2, we have

i = exp(i π/2) = cos(π/2) + i sin(π/2)

By DeMoivre's theorem,

i² = exp(i π/2)² = exp(i π) = cos(π) + i sin(π)

and it follows that i² = -1 since cos(π) = -1 and sin(π) = 0.
