Answer:
x = 107
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
Given
[tex]log_{10}[/tex] (x - 7) = 2 , then
x - 7 = 10² = 100 ( add 7 to both sides )
x = 107

A box contains 6 red pencils and 8 blue-pencils. A pencil is chosen at random and not
replaced. A second pencil is then chosen at random. Calculate the probability that at least one
of the pencils is red
Answer:
There are 14 pencils and 8 are blue
The probability of picking blue in the first pick = 8/14 =4/7.
The probability of picking blue in the second pick = 7/13 (as no replacement was there).
There are 14pencils and 6 are red.
The probability of picking red in the first pick = 6/14 =3/7
The probability of picking red in the second pick = 5/13. (as no replacement was there).
Can I please get some help with this problem?
Answer:
a = 55
Step-by-step explanation:
By exterior angle theorem:
a+10 + 44 = 2a
a= 55
Here's the proof:
Consider the same figure shown
say a+10 = x and 44 = y
Thus the remainng angle is 180 - x-y
and the exterior angle is 180- ( 180 - x- y) = x+y
Thus proved
I need help The point (1, –5) is reflected across the y-axis.
Answer:
Step-by-step explanation:
Then the x part of the point takes on the opposite sign that it currently has.
Right now it is 1. If it takes on the opposite sign, it becomes - 1So the new point is (-1,-5). Nothing happens to the - 5 when reflected across the y axis.One teacher wants to give each student 2 1 8 _ slices of pizza.

-4<=x<=4
-4
-4<=X<=6
4
-4
3 of 11
Answer:
-4 ≤ x ≤ 6
Step-by-step explanation:
When we talk of the domain, we are referring to the possible x-values
from the diagram, we can see that we have the x-values at -4 and 6
The dotted line means that -4 and 6 are in the domain
Thus, the two points represent the end and starting point of the domain
Writing this in interval notation, we have the representation as;
-4 ≤ x ≤ 6

How do I find the area?
Answer:
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square, you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Answer:
Base x Width x Height
Step-by-step explanation:

A store buys sweaters for $8 and sells them for $26. How many sweaters
does the store need to sell to make a profit of $990?
Answer:
55
Step-by-step explanation:
55 x 26 = 1430
55 x 8 = 440
1430 - 440 = 990
The store need to sell 55 sweater to earn $ 990 as profit.
Profit and Loss:Let us consider that, number of sweater needed to sell be x.
Since, cost price of one sweater is $8.
So that, cost price of x sweater[tex]=8x[/tex]
Selling price of one sweater is $26.
So that, selling price of x sweater[tex]=26x[/tex].
As we know that,
[tex]S.P-C.P=Profit\\\\26x-8x=990\\\\18x=990\\\\x=990/18=55[/tex]
Hence, the store need to sell 55 sweater to earn $ 990 as profit.

Use distributive property to simplify 3(2x - 6). SHOW ALL STEPS! Anyone able to help me with this I will gladly like it.
Answer:
6x - 18
Step-by-step explanation:
3 x 6 = 18, so thats how you get the 18 in the answer
3 x 2x = 6x, which is how you get the 6x
and theres a subraction sign so we know to put a - there.
Answer:
6x - 18
Step-by-step explanation:
3(2x - 6) =
("... - 6" means that whatever we do with the 6, we have to remember that it's negative)
3(2x - 6) =
3 * 2x + 3 * (-6) =
6x + (-18) =
(if we add a negative number then it's the same as subtracting that number)
6x + (-18) = 6x - 18
