Convert the following to logarithm form. *PLEASE GIVE EXPLANATION*
Solve the equation using the distributive property and properties of equality. 2 (x minus 8) = 68 What is the value of x?
Answer:
x=42
Step-by-step explanation:
2(x-8)=68
Distribute the 2
2x-16=68
Use the addition property of equality (add 16 to both sides)
2x=68+16
2x=84
Use the division property of equality (divide both sides by 2)
x=84/2
x=42

If x = 1, y = 7, and z = 15, determine a number that when added to x, y, and z yields consecutive terms of a geometric sequence. What are the first three terms in the geometric sequence? 3
Given:
[tex]x = 1, y = 7,z = 15[/tex]
A number is added to x, y, and z yields consecutive terms of a geometric sequence.
To find:
The number which is added to x, y, and z, then find the first three terms in the geometric sequence.
Solution:
Let the unknown number be k.
After adding k to x, y, and z, we get
[tex]x = 1+k, y = 7+k,z = 15+k[/tex]
These are the consecutive terms of a geometric sequence. So,
[tex](7+k)^2=(1+k)(15+k)[/tex]
[tex]49+14k+k^2=15+k+15k+k^2[/tex]
[tex]49+14k=15+16k[/tex]
Isolate the variable terms.
[tex]49-15=16k-14k[/tex]
[tex]34=2k[/tex]
[tex]\dfrac{34}{2}=k[/tex]
[tex]17=k[/tex]
The unknown number is 17.
Now,
[tex]x=1+k[/tex]
[tex]x=1+17[/tex]
[tex]x=18[/tex]
Similarly,
[tex]y=7+k[/tex]
[tex]y=7+17[/tex]
[tex]y=24[/tex]
And
[tex]z=15+k[/tex]
[tex]z=15+17[/tex]
[tex]z=32[/tex]
Therefore, the three terms in the geometric sequence are 18, 24, 32.
Zeke earned 23 extra credit points. Sofia earned e fewer extra credit points than Zeke. Write
an expression that shows how many extra credit points Sofia earned.
Answer:
s = 23 - e
Step-by-step explanation:
In this expression, s is equal to the amount of extra credit Sofia earns. She earns e less points than the 23 points Zeke earns.
So, s (Sofia's points) = 23 (Zeke's points) - e (the difference in points).
The expression is s = 23 - e.
Good luck ^^
Marcy needs 150 feet of fabric for her project. She uses 20% of it. How many feet of fabric did she use for her project so far? You may use a bar model or double number line.
Answer:
The answer is 120 feet of fabric
Answer:
30 feet.
Step-by-step explanation:
Steps
First, convert the percentage discount to a decimal. 20 percent of 150 is 0.20 in decimal format.
Secondly, multiply the decimal discount by the price of the item to determine the savings in dollars.
In this case, the original fabric needed equals 150 feet, you would multiply 0.2 by 150 to get the answer.
Solution
20 percent *150 =
(20:100)*150 =
(20*150):100 =
3000:100 = 30
Therefore, she used 30 feet for her project so far.

The average weight for three children was 79.6 pounds. What was the sum of their
weight?
Answer: 238.8
Step-by-step explanation:
To get an average, you add the weights together, the sum. And then you divide by how many children there was.
To go backwards, you'd times the average by the amount of children there were, 3, to get the sum
79.6 times 3 is 238.8

write 1.87 as a fraction.
Answer:
[tex]1\frac{87}{100}[/tex]
Step-by-step explanation:
A decimal is another way of representing a fraction such that the denominator of the fraction is a power of (10).
In the number (1.87), the number goes two places behind the decimal point, which means that the denominator of the fraction is (100), and the numerator is the given number excluding the decimal point.
[tex]\frac{187}{100}[/tex]
Simplify, write as a mixed number,
[tex]1\frac{87}{100}[/tex]

Rewrite without absolute value for the given conditions:
y =|x −3|+|x +2|−|x −5|, if x < −2
Answer:
y = -x - 4
Step-by-step explanation:
y =|x −3|+|x +2|−|x −5|, if x < −2
let x = -1
y1 =|x −3|
y1 = - ( x - 3 ) = -x + 3
y2 = |x +2|
y2 = - (x +2) = -x - 2
y3 = |x −5|
y3 = - (x −5) = -x + 5
y = y1 + y2 + y3
substitute back into original
y = -x + 3 - x - 2 - (-x + 5)
y = -x + 3 - x - 2 + x - 5
y = -x - 4

Answer:
-6
Step-by-step explanation:
g(-4) here x = -4
So, we have to take g(x) = x - 2
g(-4) = -4 -2 = - 6
g(1) , here x = 1 ,
So, we have to take g(a)= -x +1
g(-1) = -1 + 1 = 0
g(-4) + g(-1) = -6 +0 = -6
Find the roots: x^2−12x+32=0.
Enter your answers in the boxes (numbers only).
The answers are 4 and 8.
Because:
x^2 - 12x + 32 =
(x - 4)(x - 8)
x - 4 = 0
+4 +4
x = 4
x - 8 = 0
+8 +8
x = 8
The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greater than 152 inches?
Answer:
35
Step-by-step explanation:
35 is exactly 152 but since its asking for greater then you're right it is 36.
But since it says '>' it means not equal to so it would be:
x > 35
or
x ≥ 36
