Translate One-third of a number is 14 into an equation
Answer:
1/3x=14
answer for x is 42
Step-by-step explanation:
x represents the original number and 1/3 of the number equals 14. So 1/3x=14
So therefore 1/3x=14 which x = 42 in case if you were wondering.

No 2 please.Quick. HELP ASAP
Part A
We have 20 cards, 4 of which are kings (one of each suit). The probability of getting a king on the first draw is 4/20 = 1/5.
Answer: 1/5===========================================================
Part B
We have 20-4 = 16 cards that aren't a king out of 20 total.
The probability of getting a non-king card is 16/20 = 4/5
After selecting the first card and not putting it back, we have 20-1 = 19 cards left. Four of which are a king, so 4/19 represents the probability of getting a king on this draw.
So (4/5)*(4/19) = 16/95 is the probability of getting a king on the second draw where the first draw is not a king.
Answer: 16/95===========================================================
Part C
16/20 is the probability of getting no kings on the first draw
15/19 is the probability of getting no kings on the second draw (notice I stepped the values down by 1)
14/18 is the probability of getting no kings on the third draw
Multiplying out the fractions gives
(16/20)*(15/19)*(14/18) = 28/57
I skipped a few steps when multiplying the fractions but you get the idea.
The probability of drawing 3 cards, none of which are a king, is 28/57
Subtract this from 1 to get the complementary probability
1-(28/57) = 57/57 - 28/57 = (57-28)/57 = 29/57
This works because we have two choices: either we get no kings, or we get at least one king. So that's why the two events are complementary and their probabilities add to 1.

Can someone help me with this graph? I don't understand how to solve it
X+y=-5
-x -x
y=-x-5 is the ending equation.
How to graph:
The y-intercept, or point where the graph starts, is -5
From there go down 1, right 1.
M=-x
B=-5
Answer: m = -1 b = -5
Step-by-step explanation:
Rewrite the equation in "slope-intercept form" y = mx +b .
m is the slope
b is the y-intercept, where the graph of the line crosses the y-axis
To rewrite the equation, to get "y" alone on the left side, subtract x from both sides:
x + y = -5
-x + x + y = -x - 5 (left side -x +x =0 so "cancel")
y = -x -5
You get the slope "m" from the coefficient of x, (invisible 1, sometimes)
since there is a negative sign, the coefficient is -1 That is m, the slope.
A negative slope goes down from left to right.
For -1, down one over 1 square.
Your graph should look like the screenshot below.
I hope this helps you understand better!
Which lines are perpendicular to the line y – 1 = 1/3 (x+2)? Check all that apply.
y + 2 = –3(x – 4)
y − 5 = 3(x + 11)
y = -3x – 5/3
y = 1/3 x – 2
3x + y = 7
Answer: A. y + 2 = -3(x - 4).
C. y = -3x - 5/3 and E. 3x + y = 7

it’s me again lol pls help
Answer:
C
Step-by-step explanation:
This might look strange, but I would begin by adding 4y to both sides.
12x = 20 + 4y Subtract 20
12x - 20 = 4y Divide both sides by 4
12x/4 - 20/4 = 4y/4 Combine
3x - 5 = y

Determine which ordered pair is a solution of y= x+2/5
Wouldn’t it be (0, 2/5)?
Answer:
(-1,2/5) i'm pretty sure
Step-by-step explanation:
Answer:
(2, 2 2/5)
Step-by-step explanation:
(0, 2/5) is correct, and since the slope is 1, adding any number to both the x and the y would still make it a solution.
In this case, you could add 2 to both x and y, resulting in (2, 2 2/5).
Hope it helped, and if it did, could you consider giving me brainliest? :)

Karen earn a commission of $140.00 per course that you sell on the internet. She
sold 112 courses.
What is her commission?
Answer:
$ 15680
Step-by-step explanation:
From the question given above, we were told that Karen earn a commission of $ 140 per course.
To know her commission for selling 112 courses, we simply do the following:
Karen earn a commission of $ 140 for 1 course.
Therefore, she will ear $ X for 112 courses i.e
$ X = $ 140 × 112 course/ 1 course
$ X = $ 15680
Therefore, Karen commission for selling 112 courses is $ 15680

f (x) = (-5,
a) Find f(1) =
(1) b) Find f(5) =
(1)
Answer:
f(1) = - 5, f(5) = 6
Step-by-step explanation:
(a)
f(1) with x = 1 is in the interval x ≤ 1 , thus
f(1) = - 5
(b)
f(5) with x = 5 is in the interval x > 1 , thus f(x) = 2x - 4 , so
f(5) = 2(5) - 4 = 10 - 4 = 6

Another function I hate these things :C can someone help!
Answer:
No, this is not a function.
Step-by-step explanation:
This is not a function because not every input goes to exactly one output. In this example, 2 is listed twice. 2 goes to both 4 and 8. Because of this, it is not a function.

The ratios 5:3 and 10:6 are equivalent ratio
Is the ratio 15:12 equivalent to these?? Explain your reasoning
No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because
- 15:12 = 5:4
- 5:3
- 10:6 = 5:3
Given,
5:3 and 10:6 are equivalent ratios.
We need to see whether these ratios are equivalent to 15:12.
What are proportional ratios?The ratios which are equal are called proportional ratios.
Example:
1:2 = 5:10 = 6:12 = 7:14
5/10 = 1/2
6/12 = 1/2
7/14 = 1/2
We have,
5:3 and 10:6
- 5/3
- 10/6 = 5/3
We have,
15:12
= 15/12
= 3x5/3x4
= 5/4
We see that 5:3 and 10:6 are not equivalent to 15:!2.
Thus,
No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because
- 15:12 = 5:4
- 5:3
- 10:6 = 5:3
