7(1 - y) = -3(y-2)
What is the answer
Answer:
[tex] \huge y = \frac{1}{4} [/tex]
Step-by-step explanation:
[tex]7(1 - y) = -3(y-2)[/tex]
Expand the terms in the bracket
That's
[tex]7 - 7y = - 3y + 6[/tex]
Add 3y to both sides of the equation
[tex]7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6[/tex]
Subtract 7 from both sides by the equation
[tex]7 - 7 - 4y = 6 - 7 \\ - 4y = - 1[/tex]
Divide both sides by - 4
[tex] \frac{ - 4y}{ - 4} = \frac{ - 1}{ - 4} \\ [/tex]
We have the final answer as
[tex]y = \frac{1}{4} \\ [/tex]

There are 216 identical plastic chips numbered 1 through 216 in a box. What is the probability of reaching into the box and randomly drawing the chip numbered 170? Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Answer:
The probability of randomly drawing the chip numbered 170 is 1/216 or 0.0046
Step-by-step explanation:
Probability is the likelihood or chance of an event occurring. Probability can be determined using the formula below
Probability = Number of favorable outcome / Total number of possible outcomes.
From the question, we are to determine the probability of reaching into the box and randomly drawing the chip numbered 170.
Here, the number of favorable outcome is 1 (which is the chip numbered 170)
Total number of possible outcomes is 216 ( all the 216 identical plastic chips)
Therefore,
Probability = 1/216 or 0.0046
This is the probability of randomly drawing the chip numbered 170.
The probability of randomly drawing the chip numbered 170 is 1/216 or 0.0046

find value of x and y
Answer:
x = 74, y = 53
Step-by-step explanation:
x and 106 are supplementary angles, they add to 180. 2y and x are also supplementary angles, and using substitution, you get 2y is equal to 106, so y is 53. x will be 74 degrees.

To mail 10 letters costs $ 4.50 . How much would it cost for 12 letters? Assume the relationship is proportional.
Answer:
12 letters cost 6.30 dollars
Step-by-step explanation:
hope this helps
Answer:
$5.40 for 12 letters
Step-by-step explanation:
you need to find the cost for 1 unit then multiply that by 12, so you take the cost (4.50) and divide it by letters (10) so you get 0.45. So that is the cost of q letter, then you that that unit rate and multi[ly it by the number that you need to figure out (12) so .45x12=5.40
12 letters=$5.40

What is the slope of a line perpendicular to the line whose equation is
15x + 9y = 189. Fully reduce your answer.
We want to find the slope of a line perpendicular to 15*x + 9*y = 189.
The slope of the line perpendicular to the given line is 9/15.
First, a general line written in the slope-intercept form is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
And two lines are perpendicular if one has a slope that is equal to the inverse of the opposite of the other line's slope.
So, to find the slope of the line perpendicular to 15*x + 9*y = 189, first, we need to find the slope of this line.
To do it, we need to isolate y.
9y = -15x + 189
y = (-15/9)*x + 189/9
So the slope is -15/9
A perpendicular line to this must have a slope equal to the inverse of the opposite of this, so the slope of the perpendicular line is:
-(-9/15) = 9/15
The slope of the line perpendicular to the given line is 9/15.

Which ratios have a unit rate greater than 1? Choose ALL that apply.
Answer:
Step-by-step explanation: 7 miles: 3/4 hour, 9/8 miles: 5/6 hour, and 4 miles: 3 and 1/3 hour.
hope this helps !! <3
The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours
Unit rate is the ratio of the distance travelled o the time taken.
For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;
If distance = 9/8 miles and time = 5/6 hours
[tex]Unit \ rate =\frac{(9/8)}{(5/6)}\\Unit \ rate =\frac{9}{8} \times \frac{6}{5}\\Unit \ rate = \frac{54}{40} \\Unit \ rate =1.35 miles/hour[/tex]
Hence the ratio that has a unit rate is 9/8 miles:5/6hours
If distance = 7 miles and time = 3/4 hours
[tex]Unit \ rate =\frac{7}{(3/4)}\\Unit \ rate =\7 \times \frac{4}{3}\\Unit \ rate = \frac{28}{3} \\Unit \ rate = 9.33miles/hour[/tex]
Hence the ratio that has a unit rate is 7 miles:3/4hours

Two supplementary angles are in the ratio 2:7. Find the measure of the Acute angle.
Answer:
y=42.3333333333 (repeating)
Step-by-step explanation:
You need to find the corresponding side. You can see D H is corresponding to E C. So here is what you have to do, find x to (8x - 43) and (2x + 13).
2x + 13 + 8x - 43= 90
10x -30 = 90
+30 +30
10x = 120
/10 /10 = 12
to check if this is right take x which is 12 and plug it in.
8 x 12= 96 then 96 - 43= 53
2 x 21= 24 then 24 + 13= 37
Next you take 53 and 37 and add it together
53 + 37= 90
about that corresponding side, now you know D H and E C both equal 53
Now you can solve your equation.
53 + 2y + y= 180
53 + 3y = 180
-53 -53
3y = 127
/3 /3
y = 42.333333 (repeating)
to check if this is right take y which is 42.3333333 (repeating) and plug it in.
2y means to multiply y two times so...
42.3333333 (repeating)+ 42.33333333 (repeating)= 84.6666666 (repeating)
y = 42.333333333 (repeating)
E C = 53
add all the numbers together
42.333333 (repeating) + 84.66666666 (repating)+ 53= 180
Therefore y equals 42.33333333 (repeating)

Type the correct answer in the box. Use numerals instead of words. Use the clues to find the mystery number. It is greater than 37,493. It is less than 37,503. It is an even number. The value of the mystery number rounded to the nearest ten is less than the mystery number. The value of the mystery number rounded to the nearest thousand is greater than the mystery number.
Answer:
37,502
Step-by-step explanation:
With the provided details we have:
Range of number = 37,493 - 37,503
The number is even number
Therefore, possible options are:
37,494
37,496
37,498
37,500
37,502
When number rounded to nearest tens, is less than the original number
Rounding off above numbers to nearest tens we have
37,490
37,500
37,500
37,500
37,500
There is only 2 numbers which full fill the condition of original number number being smaller than the rounded off number.
37,494 and 37,502
The next condition is on rounding to nearest 1,000's
37,494 rounded to 37,000
37,502 rounded to 38,000
Provided that the rounded number in 1000's is more than the original mystery number.
37,000 is less than 37,494 thus not feasible.
38,000 is more than 37,502
This is the mystery number.

Walter and Brian each have a CD collection. • The number of CDs in Walter's collection can be represented by x. • The number of CDs in Brian's collection is 3 times the number in Walter's collection. • The total number of CDs in both collections is 144. What is x, the number of CDs in Walter's collection?
Answer:
Number of CDs in Walter's collection = x = 36
Step-by-step explanation:
x denotes number of CDs in Walter's collection.
Also, the number of CDs in Brian's collection is 3 times the number in Walter's collection.
Number of CDs in Brian's collection [tex]=3x[/tex]
Total number of CDs in both Walter's collection and Brian's collection = 144
[tex]x+3x=144\\4x=144\\x=\frac{144}{4}\\ x=36[/tex]
So,
Number of CDs in Walter's collection = x = 36
