Answer:
y = -3x/2 + 5/2
Step-by-step explanation:
Well, basically what you do is modify it so that y is on one side.
3x+2y = 5
2y = 5-3x
y = (5-3x)/2
y = 5/2 -3x/2
So, the answer is the second option.
Answer:
B
Step-by-step explanation:
3x + 2y = 5
Our goal is this form:
y = mx + b
- move 3x to right anc change its sign
2y = -3x + 5
- divide each member by 2
y = -3/2 x + 5/2

Find mBFE, help ASAP!!!
Answer: C
<BFE is 148 degrees
Step-by-step explanation:
We have angles <BFC (57 degrees) and <CFD (34 degrees), but what is <DFE?
1. The angle symbol in the vertexes shows that <BFC is congruent to <DFE, meaning that they are the same
2. Knowing this, we can safely say that <DFE is equal to 57 degrees because <BFC is also 57 degrees.
3. Now, we have all the angles we need to find out <BFE.
4. <BFC+<CFD+<DFE=<BFE
5. Substitute to get
57+34+57=<BFE
91+57=<BFE
148=<BFE
6. Now we know that the answer is 148 degrees.
suppose two soccer teams consist of players with a combined average height of 66 inches. if team a has an average height of 68 inches and has twice as many members as team b, what is the average height of team b
Answer:
The average height of team b is 62 inches.
Step-by-step explanation:
Mean:
The mean of a data-set is the sum of all values in the data-set divided by the number of values, that is:
[tex]M = \frac{s}{n}[/tex]
Sum:
Team a: Mean of 68 inches, 2x members.
Team b: Mean of y inches, x members.
So
[tex]s = 68*2x + yx = x(136 + y)[/tex]
Number of athletes:
[tex]n = 2x + x = 3x[/tex]
What is the average height of team b?
[tex]66 = \frac{x(136+y)}{3x}[/tex]
[tex]66 = \frac{136 + y}{3}[/tex]
[tex]136 + y = 198[/tex]
[tex]y = 198 - 136 = 62[/tex]
The average height of team b is 62 inches.

What is 46.7% of
4/5?
Answer:
0.3736
Step-by-step explanation:
46.7 percent of [tex]\frac{4}{5}[/tex] is 0.3736.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct," "pct," and occasionally "pc" are also used, the percent sign, " percent ", is frequently used to signify it. A % is a number without dimensions and without a standard measurement.What is a fraction?A number is stated as a quotient in mathematics when the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.Solution -To find 46.7% of [tex]\frac{4}{5}[/tex].
So,
[tex]\frac{46.7}{100}[/tex] × [tex]\frac{4}{5}[/tex]
[tex]\frac{0.467}{100}[/tex] × [tex]\frac{4}{5}[/tex]
⇒ [tex]0.3736[/tex]
Therefore, 46.7% of [tex]\frac{4}{5}[/tex] is 0.3736.

If 142 adults are randomly selected, what is the probability that the sample mean would differ from the population mean by more than 1.5 kilograms
Complete question;
The mean weight of an adult is 76 kilograms with a variance of 100.
If 142 adults are randomly selected, what is the probability that the sample mean would differ from the population mean by more than 1.5 kilograms
Answer:
7.34% 0r 0.0734
Step-by-step explanation:
We have mean u = 76
Standard deviation = square root of variance
Sd = √100 = 10
N = 142
S = 10/√142
= 10/11.92
= 0.84
X is going to differ by more than 1.5 or less than 1.5
76-1.5 = 74.5
76+1.5 = 77.5
At x = 74.5
Z = (74.5-76)/0.84 = -1.79
At x = 77.5
Z = (77.5-76)/0.8 = 1.79
P value of z at -1.79 = 0.036
P value of z at 1.79 = 0.9633
0.9633-0.0367 = 0.9266
Which is 92.66% probability of differing by 1.5
Probability it differs by more:
P+92.66 = 100
P = 100-92.66
= 7.34% or 0.0734

Find the amount of tax and the selling price
Answer:
$71.415 or $71.42 is the selling price and the taxing is 1
Step-by-step explanation:
This is because I just rounded that extra 5 to make the 41 cents into 42 cents also y=79.35(.9) is the equation you needed to solve so just put 79.35(.9) into a calculator and you'll get 71.415 also 10% turns into a decimal 0.10 and then you subtract it from 1 as a whole and you'll get 0.9. I'm not really a mathmatician but I just got done learning this so I know what to do.

Find area of a circle having a radius 10.5cm and a diameter 17.5cm
Answer:
110.5π
Step-by-step explanation:
The formula for the area of a circle is π r ²
R stands for radius. So, the radius is 10.5, you have to square it meaning 10.5 * 10.5.
110.5 and now you multiply by π so the answer is 110.5π

solve for q 36q² − 64 = 0
36q² − 64 = 0
=> 36q² = 0 + 64
=> 36q² = 64
=> q² = 64/36
=> q² = 16/9
=> q = √(16/9)
=> q = √16/√9
=> q = ± 4/3
Answer:
q =±4/3
Step-by-step explanation:
36q² − 64 = 0
Add 64 to each side
36q² =64
Divide each side by 36
36q² /36 =64/36
q² =64/36
Take the square root of each side
sqrt(q²) =± sqrt(64/36)
q = ±8/6
q =±4/3

Washington had
hits. Sanchez had
hits

Answer:
Washington had 196 hitsSanchez had 194 hitsStep-by-step explanation:
Let s represent the number of hits Sanchez had. Then Washington had (s+2) hits, and their hit total was ...
s +(s+2) = 390
2s = 388 . . . . . . subtract 2
s = 194 . . . . . . . . divide by 2
Sanchez had 194 hits; Washington had 196.
Peter, Jan, and Maxim are classmates. Their total score for the last test was 269. Peter's score was more than the sum of Jan's and Maxim's scores. What could be Peter's least possible score?
Answer:
135
Step-by-step explanation:
Given that :
Total score obtained by Peter, Jan and Maxim = 269
Let :
Peter's score = x
Jan's score = y
Maxim's score = z
x + y + z = 269
x > (y + z)
For x to be greater Than y + z ;
Then x > (269 / 2) ; x > 134.5
The least possible x score is 135
Hence, Peter's least possible score is 135.
