Step-by-step explanation:
solve the equation. 7+3lnx=20
Answer:
Simplifying
7 + 3lnx = 15
Solving
7 + 3lnx = 15
Solving for variable 'l'.
Move all terms containing l to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 3lnx = 15 + -7
Combine like terms: 7 + -7 = 0
0 + 3lnx = 15 + -7
3lnx = 15 + -7
Combine like terms: 15 + -7 = 8
3lnx = 8
Divide each side by '3nx'.
l = 2.666666667n-1x-1
Simplifying
l = 2.666666667n-1x-1

Answer:
angle JKL is 106
Step-by-step explanation:
an isosceles triangle means two sides are the same and the bottom two angles are the same length. So you would equal the two equations and solve it to get x. Then replace one of the equation's x with the number you got, which would be 5, and solve that. Since both bottom angle are the same, the other angle would be the same degree, 37*. A triangle is 180* total, so subtract that by two 37's and you'll get the answer.

30% of what number is 150? A. 500 B. 50 C. 45 D. 200
Answer:
500
Step-by-step explanation:
.
Answer:
A. 500
Step-by-step explanation:
We know that it can't be B. or C. since it has to be greater than 150, so (I know this isn't the way to do it) bet is you try multiplying your leftover answers you have by .3 you would see that 200 times .3 is 60, so that isn't it but 500 times .3 is 150!
I hope this helps and you have a great day! :)

6=xy does this show direct variation Explain your reasoning. ANSWER THIS PLZ
Answer:
No. It is an inverse variation.
Step-by-step explanation:
6= xy
Making y the subject of formula:
[tex]y = \frac{6}{x} [/tex]
For a direct variation, the equation would be in the form of y=kx, where k is a constant.
However, the equation above is in the form of [tex]y = \frac{k}{x} [/tex].
Thus, 6=xy does not show direct variation.
The work of a student to solve the equation 2(3x − 4) = 8 + 2x + 4 is shown below:
Step 1: 2(3x − 4) = 8 + 2x + 4
Step 2: 5x − 6 = 12 + 2x
Step 3: 5x − 2x = 12 + 6
Step 4: 3x = 18
Step 5: x = 6
In which step did the student first make an error and what is the correct step? (5 points)
A. Step 2; 6x − 6 = 2(6 + x + 2)
B. Step 2; 6x − 8 = 12 + 2x
C. Step 3; 5x − 2x = 12 − 6
D. Step 3; 5x + 2x = 12 + 6
Answer:
B. Step 2; 6x - 8 = 12x + 2x
Step-by-step explanation:
Option B is correct, the student first make an error in step 2 and the correct step is 6x − 8 = 12 + 2x.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 2(3x − 4) = 8 + 2x + 4
Two times of three x minus four equal to eight plus two times of x plus four.
The work of student
Step 1: 2(3x − 4) = 8 + 2x + 4
Step 2: 5x − 6 = 12 + 2x
Step 3: 5x − 2x = 12 + 6
Step 4: 3x = 18
Step 5: x = 6
The student made a error in step 2.
After applying to the distributive property to the equation
6x-8=8+2x+4
The correct step is 6x-8=2x+12
Hence, Option B is correct, the student first make an error in step 2 and the correct step is 6x − 8 = 12 + 2x.

Alia has a AED 20 gift card for an online music store. All songs at the store have the same price. After Alia buys 3 songs, the balance on the card is AED 16.25. What will be the remaining balance on the card after he buys 5 more songs
Answer:
Remaining balance = AED 13.75
Step-by-step explanation:
Given that:
Amount of gift card = AED 20
Amount left after buying 3 songs = AED 16.25
Cost of 3 songs = 20 - 16.25 = AED 3.75
Cost per song = [tex]\frac{3.75}{3}[/tex]
Cost per song = AED 1.25
Cost of 5 songs = 5(1.25) = AED 6.25
Remaining balance = 20 - 6.25 = AED 13.75
Hence,
Remaining balance = AED 13.75

what is the standard form of (6x^2-8x-7)+(8x^2-76x)
Answer: 14x^2 - 84x - 7
====================================================
Explanation:
The like terms 6x^2 and 8x^2 combine to 14x^2
The like terms -8x and -76x combine to -84x
Nothing pairs with the -7, so its stays as is.
Standard form is where we list the terms in decreasing exponent order. We can think of -84x as -84x^1 and the -7 as -7x^0. So 14x^2 - 84x - 7 would be the same as 14x^2 - 84x^1 - 7x^0. The exponents count down: 2,1,0.
The final answer is a trinomial since it has three terms. It is also a quadratic because the degree (highest exponent) is 2.

Given: h(t) = 2t - 5,
Solve for the following.
Part A. h(-4) = ?
Part B. h(t) = 23, then t = ?
I
Part C. h(13) = ?
Part D. h(t) = -33, then t = ?
Please show your work
Step-by-step explanation:
Part A:
h(-4) = 2(-4) - 5 = -13.Part B:
h(t) = 23, 2t - 5 = 23, 2t = 28, t = 14.Part C:
h(13) = 2(13) - 5 = 21.Part D:
h(t) = -33, 2t - 5 = -33, 2t = -28, t = -14.The value of h(-4) for the given function is -13.
The given function is h(t) = 2t - 5.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Part A:
Put t=-4 in the given function, we get
h(-4) = 2(-4)-5
= -8-5
= -13
Part B:
Substitute h(t)=23 in the given function, we get
23=2t-5
⇒2t=23+5
⇒2t=28
⇒t=14
Part C:
Put t=13 in the given function, we get
h(13)=2(13)-5
= 26-5
= 21
Substitute h(t)=-33 in the given function, we get
-33=2t-5
⇒2t=-33+5
⇒2t=-28
⇒t=-14
Therefore, the value of h(-4) for the given function is -13.

A circular mirror has a diameter of 22 inches. Which measurement is closest to the area of the mirror in square inches
Answer:
379.94 square inches, or 379.94 in².
Step-by-step explanation:
The area of a circle is π r². The diameter of the circle is listed as 22 inches, and the radius, or "r", is equal to half of the diameter. So, half of 22 is 11.
Since the formula says r², 11 needs to be squared, or multiplied once by itself. 11 x 11 = 121, so the last part of the equation is to multiply 121 by π. Because pi is an irrational number that never ends, it is commonly accepted to use 3.14, or the first three digits of pi, as the value of pi in an equation.
With that, 121 x 3.14 = 379.94, giving a final answer of 379.94 in².
