What is the solution of 5/2x-7=3/4x+14
A. X=-6
B. X=6
C. X=8
D. X=12
Answer x=12
Step-by-step explanation:
5/2x-7=3/4x+14
+7. +7
5/2x=3/4x+21
-3/4x -3/4x
5/2-3/4=7/4x
7/4x=21. since there's a fraction on one side, multiply 4 with 21
7x=84
divide and you'll get x=12
[tex] \frac{5}{2} x(4) - 7(4) = \frac{3}{4} x(4) + 14(4) \\ 10x - 28 = 3x + 56[/tex]
Solve the equation for x-term.[tex]10x - 3x = 56 + 28 \\ 7x = 84 \\ x = \frac{84}{7} \\ x = 12[/tex]
Answer[tex] \large \boxed {x = 12}[/tex]

f(x) =2x+4 translate 7 units left
Answer:
[tex]f'(x) = 2x - 10[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2x + 4[/tex]
Required
Translate 7 units left
When a function f(x) is translated b units to the left, the resulting function is:
[tex]f'(x) = f(x-b)[/tex]
In this case:
[tex]f(x) = 2x + 4[/tex]
[tex]b = 7[/tex]
[tex]f'(x) = f(x-b)[/tex] becomes
[tex]f'(x) = f(x - 7)[/tex]
Calculating [tex]f(x-7)[/tex]
[tex]f(x-7) = 2(x-7)+4[/tex]
[tex]f(x-7) = 2x-14+4[/tex]
[tex]f(x-7) = 2x-10[/tex]
So:
[tex]f'(x) = 2x - 10[/tex]

Which expression is equivalent to the given expression? Assume the denominator does not equal zero.
The final exam grade of a statistics class has a skewed distribution with mean of 79 and standard deviation of 8.2. If a random sample of 35 students selected from this class, then what is the probability that average final exam grade of this sample is between 76 and 82
Answer:
0.9696
Step-by-step explanation:
Given that:
Mean, m = 79
Standard deviation, s = 8.2
Sample size, n = 35
Probability that final exam grade of the sample is between 76 and 82
P(76 < x < 82)
P(x < 82) - P(x < 76)
Using the relation :
Z = (x - m) / (s/sqrt(n))
s / sqrt(n) = 8.2/sqrt(35) = 1.3860529
P(x < 82) - P(x < 76)
P[(82 - 79) / 1.3860529] - P[(76 - 79) / 1.3860529]
P(Z < 2.1644) - P(Z < - 2.1644)
Using the Z probability calculator :
0.98478 - 0.015217
= 0.969563
Hence, probability = 0.9696

Heather's school is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 6 adult tickets and 7 student tickets for a total of $120. The school took in $168 on the second day by selling 12 adult tickets and 2 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answer:
Price of adult ticket = x = $13
Price of student ticket = y = $6
Step-by-step explanation:
Let Price of adult ticket = x
Price of student ticket = y
Now, making equations:
On the first day of ticket sales the school sold 6 adult tickets and 7 student tickets for a total of $120. The equation will be:
[tex]6x+7y=120[/tex]
The school took in $168 on the second day by selling 12 adult tickets and 2 student tickets. The equation will be:
[tex]12x+2y=168[/tex]
Now, solving the equations simultaneously to find values of x and y.
Let:
[tex]6x+7y=120--eq(1)\\12x+2y=168--eq(2)[/tex]
Multiply eq(1) by 12 and then subtract both equations
[tex]12x+14y=240\\12x+2y=168\\-\:\:\:-\:\:\:\:\:\:\:\:\:-\\--------\\12y=72\\y=\frac{72}{12}\\y=6[/tex]
So, we get value of y: y=6
Now, Put value of y in equation 1 to find value of x
[tex]12x+2y=168\\Put\:y=6\\12x+2(6)=168\\12x+12=168\\12x=168-12\\12x=156\\x=\frac{156}{12}\\x=13[/tex]
So, we get value of x: x=13
The answer would be:
Price of adult ticket = x = $13
Price of student ticket = y = $6

what is the percent error if the bolt is actually 2.5 inches long is measured to be 2.6 inches long?
Given :
Actual length of the bolt is 2.5 inches.
Measured length of the bolt is 2.6 inches.
To Find :
The percent error of the bolt.
Solution :
We know, percentage error is given by :
[tex]\delta =| \dfrac{Actual\ Value - Expected\ Value}{Expected\ Value}|\times 100\\\\\delta =| \dfrac{2.6-2.5}{2.5}|\times 100\\\\\delta = 4 \%[/tex]
Therefore, the percentage error in the bolt is 4% .

A 32-ounce tub of yogurt contains 5 servings. How many ounces of yogurt are in 1
serving?
Answer:
32/5 ounces or approximately 6.4 ounces.
Step-by-step explanation:
We are trying to find the unit rate, so divide 32 by 5 to see how many ounces in just 1 serving.
Answer:
6.4 Ounces in 1 serving
Step-by-step explanation:
Here to find how many ounces of yogurt there are in 1 serving:
we create an expression:
[tex]\frac{x}{1} = \frac{32}{5}[/tex]
Then we simplify:
5x = 32
x= 32/5
x=6.4 Ounces
