Answer:

x = 8

Step-by-step explanation:

Hi there!

We're given that OB is the angle bisector of angle AOC.

An angle bisector splits an angle into 2 equal halves. Therefore, angles AOB and BOC are equal.

We're given that angle AOB is 8x degrees and angle BOC is 16x-64 degrees.

Set up an equation:

[tex]8x=16x-64[/tex]

Combine like terms:

[tex]-8x=-64\\x=8[/tex]

Therefore, x = 8.

I hope this helps!

Answer:

17/5

Step-by-step explanation:

put the value of pi in 2/3p+3

now,

[tex] \frac{2}{3} \times \frac{3}{5} + 3[/tex]

3 cancels 3 and

2/5 +3

=

[tex] \frac{2 + 3 \times 5}{5} [/tex]

hence your answer will be 17/5

Answer:

5 4/9

Step-by-step explanation:

Convert a mixed number 2 19

to a improper fraction: 2 1/9 = 2 19 = 2 · 9 + 19 = 18 + 19 = 199

Answer:

7 / 9

Step-by-step explanation:

You cannot simplify this fraction any more. The two fractions have the same denominator you can just add the numerators.

Answer:

the factored form of 9x²-4 is (3x-2)(3x+2)

Answer:

(12 + x)/(15 + x) = 85/100

Step-by-step explanation:

12/15 = 0.8

She currently has an 80% rate.

To raise it, she needs to make x shots. Since she makes all x shots, we add x to both the number of shots made and attempts.

She will make 12 + x shots in 15 + x attempts.

We want that rate to be 0.85 which is the same as 85%.

(12 + x)/(15 + x) = 85/100

(12 + x)/(15 + x) = 17/20

20(12 + x) = 17(15 + x)

240 + 20x = 255 + 17x

3x = 15

x = 5

Answer:

The equation is (12 + x)/(15 + x) = 85/100.

Answer:

4/3 or 1 1/3

Step-by-step explanation:

So if y = 6, when x = 2/3. Then, x would equal 1 and 1/3, because 12 is twice the amount of 6, so you'd also multiply 2/3 by 2.

(To multiply a whole number by a fraction, first multiply the whole number by the numerator and then divide that by the denominator. For example: 2 × 2 = 4, since you can't really divide 4 by 3 it would stay as is, but you can turn it to a mixed number. 4/3 is the same as 1 whole and an extra 1/3, or in other words 1 1/3).

Hope this helped :)

Answer:

7.35

Step-by-step explanation:

4/7w=4.2

multiply both sides by 7

24/7w=29.4

simplify

4w=29.4

divide both sides by 4

w=7.35

Answer:

w equals 7.35

Step-by-step explanation:

7 times 4/7w = 4.2 times 7

4w = 29.4

Divide: 4w/4 = 29.4/4

w = 7.35

Answer:

53 divided by 3 would be $17.66

so 17.66 times 9 would be $158.94

Answer:

158.4 dollars

Step-by-step explanation:

so first of all the three tickets were 53 dollars so we divide the dollars and the no of tickets like this 53÷3 = 17.6 dollars

so since each ticket is 17.6 dollars now we know that Rosie wants to purchase 9 tickets so we will multiply the no of tickets by dollars per ticket like this

9×17.6= 158.4 dollars

and 158.4 is your answer

We can solve for t by making it the subject of the equation.

since   I = Prt             [divide both sides by Pr]

Answer:

0.2 or 1/5

Step-by-step explanation:

-4(50x - 20) = 10x + 15 + 23

-200x + 80 = 10x + 38

80 = 210x + 38

42 = 210x

0.2 = x

Hope this helps! Pls give brainliest!

Answer: x = 1/5 or 0.2

Step-by-step explanation:

-4(50x-20)=10x+15+23

-200x +80=10x+38

-80 -80

-200x=10x-42

-10x. -10x

-210x = -42

/-42. /-42

= 5

Answer:

Answer:

y=4x+3

=)4x=y-3

=)x=(y-3)/4

Answer:

[tex]\frac{y - 3}{4}[/tex]

Step-by-step explanation:

To make x the subject, first, subtract 3 from both sides:

y = 4x + 3 → y - 3 = 4x

Next, divide both sides by 4 to get x on its own:

y - 3 = 4x → (y - 3)/4 = x

Hope this helps

Answer:

here's the answer it's :

x=-28

y=-18

z=-16

Answer:

The slope of Function A is less than the slope of Function B.

Step-by-step explanation:

Using the slope formula:

m = (y2 - y1)/(x2 - x1)

and the following ordered pairs from Function A:

(x1, y1) = (-5, -3)

(x2, y2) = (-10, -8)

m = (y2 - y1)/(x2 - x1)

[tex]m = \frac{-8 - (-3)}{-10 - (-5)} = \frac{-8 +3}{-10+5} = \frac{-5}{-5} = 1[/tex]

Since Function A's slope = 1, and Function B's slope = 4, then it means that the slope of Function A is lesser than the slope of Function B.

The equation, y = 6/13x, represents a proportional relationship.
