What's the sum of 2/5 and 2/4?
A. 8/20
B. 6/7
c. 9/10
D. 10/20

Answer:

what? better explanation

Answer:

The answer is 15.

Step-by-step explanation:

d =  sqr. root of (x_2 - x_1)^2 + (y_2-y_1)^2}

= sqr. root of  7- - 2 ^ 2 + 3 - - 9 ^ 2

= sqr. root of 9 ^ 2 + 12 ^ 2

= sqr. root of 81 + 144

= sqr. root of 225

= 15

Answer:

x=1/3

Step-by-step explanation:

(18x+3)^2=81

square root both sides

18x+3=9

subtract 3 from both sides

18x=6

divide 18 on both sides

x=1/3

Answer: y=3/2x+7

Step-by-step explanation:

To find the equation of the line that passes through the given point, let's first convert the given equation to slope-intercept form.

3x-2y=2           [subtract both sides by 3x]

-2y=-3x+2        [divide both sides by -2]

y=3/2x-1

Now that we have the equation in slope-intercept form, we know that the slope must stay the same because parallel lines NEVER touch. All we have to do is plug in the given point to find the y-intercept.

-2=3/2(-6)+b    [multiply]

-2=-9+b            [add both sides by 9]

b=7

Now, we know that the parallel equation is y=3/2x+7.

Answer:

1.) x = 30 ; 150°   2.) x = 30 ; 50°  3.) x = 40 ; 122°

Step-by-step explanation:

Each one of the problems revolves around vertical angles. Verticle angles are equal to each other.

1.)

5x = 3x + 60

2x = 60 (Subtracted 3x on both sides.)

x = 30 (Divided 2 on both sides.)

Know that we know the variable's value, time to find the angles.

5(30) = 3(30) + 60

150 = 150

This means the angles are 150°.

2.)

3x - 40 = x + 20

2x - 40 = 20

2x = 60

x = 30

3(30) - 40 = (30) + 20

90 - 40 = 50

50 = 50

This means the angles are 50°.

3.)

5x - 78 = 3x + 2

2x - 78 = 2

2x = 80

x = 40

5(40) - 78 = 3(40) + 2

122 = 122

This means the angles are 122°.

The value of x is 30° and the unknown angle is 150°.

We need to find the unknown angles from the given figure.

The vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

From figure 1:

(5x)°=(3x+60)°

⇒5x-3x=60

⇒2x=60

⇒x=30

So, (5x)°=(3x+60)°=150°

From figure 2:

(3x-40)°=(x+20)°

⇒3x-x=60

⇒2x=60

⇒x=30

So, (3x-40)°=(x+20)°=50°

From figure 3:

(3x+2)°=(5x-78)°

⇒5x-3x=78+2

⇒2x=80

⇒x=40

So, (3x+2)°=(5x-78)°=122°

Therefore, the value of x is 30° and the unknown angle is 150°.

Answer:

2 and 4/5

Step-by-step explanation:

If you ate 2/5 of a pizza in 1/7 of an hour then you need to multiply 2/5 by 7

Start by converting 7 into a fraction

7 = 7/1

then multiply the top and bottom of the fractions

2 * 7 = 14

5 * 1 = 5

2/5 * 7/1 = 14/5

Convert 14/5 into a mixed number

14/5 = 2 and 4/5

Answer:

z = -4

Step-by-step explanation:

I'm going to assume you mean solve for z.

5z - 8 = -28

add 8 to both sides.

5z = -28 + 8

5z = -20

divide both sides by 5

z = -4

Answer: The answer would be −4.

First add eight to both sides.

5z−8+8=−28+8

5z=−20

Now divide both sides by five.

5z  divided by five = -20 divided by 5.

z=−4

Answer:

x = [tex]\frac{ab}{b+a}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{a}[/tex] + [tex]\frac{1}{b}[/tex] = [tex]\frac{1}{x}[/tex] ( express the sum on the left as a single fraction )

[tex]\frac{b+a}{ab}[/tex] = [tex]\frac{1}{x}[/tex] ( cross- multiply )

x(b + a) = ab ← divide both sides by (b + a)

x = [tex]\frac{ab}{b+a}[/tex]

u= 6x-35/w Hope this helped <3

Step-by-step explanation:

Let's solve for u.

uw=6x−35

Step 1: Divide both sides by w.

Step-by-step explanation:

This all will be attempted according to Figure.

We can see in figure ,

[tex]\tt{UW = 4x-20+19}[/tex] _____(1)

Now, question says that:-

[tex]\tt{UW = 6x - 35}[/tex]_______(2)

Equating ,

(1)=(2)

So,

[tex]\tt{4x-20+19 = 6x - 35}[/tex]

[tex]\tt{4x-1 = 6x - 35}[/tex]

[tex]\tt{4x-6x = +1- 35}[/tex]

[tex]\tt{-2x = -34}[/tex]

[tex]\tt{x = \dfrac{34}{2}}[/tex]

[tex]\tt{x = 17}[/tex]

Now, we need UW.

Placing it in any Equation, Let me take (2),

6(17) -35

= 102 - 35

So, 67 is the answer.
