can someone solve 14 = 8k - 3 + 1 step by step please?
Answer:
k=2
Step-by-step explanation:
First your going to switch sides
8k - 3 + 1 = 14
Then your going to do - 3 + 1 = -2
Then you get this equation
8k - 2 = 14
Then your going to add 2 to both sides
8k - 2 + 2 = 14 + 2
Then simplify
8k = 16
Then divide both sides by 8
8k/8 = 16/8
Then simplify again and heres
your answer
k=2
Answer:
14 = 8k - 3 + 1 ; k=2
Step-by-step explanation:
14= 8k - 3 + 1
switch sides:
8k -3 + 1 =14
add/subtract the numbers:
8k-2+2=14+2
simplify:
8k=16
divide both sides by 8:
8k/8 = 16/8
simplify:
k=2

Answer:
Johnny had seven and a half cookies. His sister gave him two, while his sister was giving him two his brother stuck half of one in his pocket. How many cookies DO HE GOT?
Step-by-step explanation:
X represents the amount of cookies Johnny has.
The value of x is [tex]7\frac{1}{2}[/tex]
What is an equation?'An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.'
According to the given problems,
Let us assume,
Janet had 10 biscuits. She gave her daughter 2 biscuits and a monkey nearby snatched half of one biscuit and ran. She needs to know the number of biscuits left with her counting half of the biscuit left with her.
Let the number of biscuits left be x,
Number of biscuits Janet gave to her daughter = 2
Number of biscuits the monkey took = [tex]\frac{1}{2}[/tex] of a biscuit.
Total number of biscuits lost = 2 + [tex]\frac{1}{2}[/tex]
= [tex]2\frac{1}{2}[/tex]
Therefore,
Number of biscuits left with Janet,
⇒ x + [tex]2\frac{1}{2}[/tex] = 10
⇒ x + [tex]\frac{5}{2}[/tex] = 10
⇒ x = 10 - [tex]\frac{5}{2}[/tex]
⇒ x = [tex]\frac{15}{2}[/tex]
⇒ x = [tex]7\frac{1}{2}[/tex]
Hence, we can conclude, Janet has [tex]7\frac{1}{2}[/tex] biscuits left.

−4 > −4/3s
PLEASE ANSWER ASAP!!! Which one is the correct answer? I'll give brainliest to the first correct answer.
Answer:
C
Step-by-step explanation:
Since the ratio is 5:3, that means if Adam has 5 songs, his mother has 3. That means we can eliminate the last table. We can also eliminate the first table since it isn't possible. Let's look at B, 5x6 is 30, but 3x6 is not 18, so that is incorrect. This means the table is C. Let's make sure, though. The first row is correct. 5x2 is 10 and 3x2 is 6, so the second row is correct. 5x5 is 25 and 3x5 is 15, so the entire table is correct.

Point R is located 5 units to the right of 3 on the number line. What is the value of the point that is opposite point R?
Answer:
-8
Step-by-step explanation:
A number line has negative numbers on the left and positive on the right
5 units to the right of 3 would be 3+5 which would equal 8
The opposite of a number is another number that is the same distance from zero
In this case, the opposite of 8 would be -8 because 8 is 8 away from zero, and so is -8

can someone help me understand why I’m in 8th grade pre algebra struggling, while somehow managing to understand basic calculus
Hope this helps, and I understand! 」(￣▽￣」)
My experience in higher education was unusual and erratic. I eventually earned a master’s degree in International Studies, but long before that I was a high-school dropout.
One thing I haven’t talked about much is that I’ve never been able to learn higher math: algebra, geometry, calculus, or anything of the sort. It’s not for lack of trying, or at least it wasn’t for a while. (I have zero interest in trying to learn it these days.)
No, I tried and I just couldn’t learn. I tried over and over and it never got any easier. In the U.S. educational system, I failed to progress beyond seventh or eighth grade level math. I’m not sure what the equivalent is elsewhere, but for me I could understand the very elementary principles of algebra and geometry but nothing beyond that.
Lots of people tried to help. I read books and went to study groups. But no matter what I did, it didn’t sink in.
