15

Step-by-step explanation:

divided 30 by 2 only work for the 50%

Oh i think this is wrong but i tried sorry

Answer:

$15 :)

Step-by-step explanation:

You have to move the decimal 2× to the left on the 15%, then multiply it by $30 ♡

Answer:

∠3 = 95°

∠4 = 85°

Step-by-step explanation:

Angle 3 and the angle that is already given are Corresponding angles meaning they will be equal.

Angle 3 and Angle 4 are Supplementary angles so their degrees add up to 180°.

Hope this helps!

Answer:

(2,-1)

Step-by-step explanation:

If you start at (2,-1) and go 3 units right, you land at (5,-1). Then, when you go up 4 units you land at (5,3)

Answer:

See explanation

Step-by-step explanation:

For any line, with slope [tex]m[/tex] and y-intercept [tex](0, b)[/tex] the line is [tex]y=mx+b[/tex].

1)

[tex]m=6, b=-2[/tex], Line: [tex]y=6x-2[/tex]

2)

[tex]m=2/3, b=5[/tex], Line: [tex]y=2/3*x+5[/tex]

3)

[tex]m=-5, b=0[/tex], Line: [tex]y=-5x[/tex]

4)

[tex]m=0, b=-1[/tex], Line: [tex]y=-1[/tex]

5)

[tex]m=-1, b=4[/tex], Line: [tex]y=-x+4[/tex]

Answer:

Q9. ?=53° (corr angles, u//v)

Q10. ?=58° (alt angles, u//v)

Answer:

0.25

Step-by-step explanation:

Half of a tenth in 5 hundredths.

To find the midpoint of 0.2 and 0.3, think of it as 20 and 30.

What would be the midpoint of 20 and 30? 25.

Therefore, 0.25 would be the midpoint of 0.2 and 0.3

Answer: 2 soulutions

Step-by-step explanation: Just factor them and solve the answer would be x = 4 √3 + 8 in its exact form and x = 14.92820323... in its decimal form

Answer:

a. Find the largest and smallest numbers and then subtract the smallest from the largest number.

b. 52

Step-by-step explanation:

Range Definition: Difference between largest and smallest numbers.

1. Find the largest and smallest numbers;

Biggest: 17|5 (175)

Smallest: 12|3 (123)

2. Subtract the smallest number from the largest number;

175 - 123 = ?

? = 52

Answer:

A goes with the sum of a number and 3

B goes with the product of 4 and a number

C goes with 2 less than a number

D goes with the quotient of 5 divided by a number

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Let the number be x

3x + 7=15-x

4x = 8

x=2

Answer:

4:3

Step-by-step explanation:

There are 4 A's and 3 B's, so the ratio would be 4:3.

The ratio would not be 3:4, because you are asking for A's to B's, and not B's to A's.

Answer:

4:3

Step-by-step explanation:

There are 4 A's in this set and only 3 B's. Often confused as 3:4, however, that would be the ratio of B's to A's. This ration can't be simplified either leaving it at 4:3.

Answer:

Tn=a+(n−1)d, where a= First term, d= Difference between terms ... (2)

Equating (1) and (2)

6n+5=a+(n−1)d

6n+5=a+nd−d ..... (3)

Equating n terms:6n=nd

d=6 ...... (4)

Substituting (4) in (3)

6n+5=a+6n−6

5=a−6

a=11 ..... (5)

Now

Sn=2n(2a+(n−1)d)

Sn=2n(a+Tn) ....... (6)

Substituting (1) and (5) in (6)

Sn=2n(11+6n+5) 

Sn=2n(16+6n) 

Sn=n(8+3n)

Answer:

x<0.5

Step-by-step explanation:

Hello lzukuXKachan!

[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]

Solve 2(1 – x) > 2x.

x < 2

x < 0.5

x > 0.5

x > 2

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex]2 ( 1 - x ) \gt 2 x[/tex]

Firstly, cancel out 2 from both sides of the equation. Now, the equation will be....

[tex]1 - x > x[/tex]

Now, subtract x from both sides.

[tex]1 - x - x > 0[/tex]

Combine -x & -x. It'll be one -2x.

[tex]1-2x>0 [/tex]

Again subtract 1 from both the sides. Remember :- any number subtracted from 0 will result in its negation

So, it'll be -1.

[tex]-2x>-1 [/tex]

Divide both sides by -2.

[tex]x<\frac{-1}{-2} \\ [/tex]

Remove the negative signs. (negative ÷ negative = positive)

[tex]x<\frac{1}{2} \\ = \large\boxed{ \boxed{ \bf \: x < 0.5}}[/tex]
