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.

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.
solve the inequality
4b−4≤−20
Answer:
b ≤ -4
Step-by-step explanation:
4b−4≤−20
4b - 4 + 4 ≤ - 20 + 4
4b ≤ -16
Divide both sides by 4
b ≤ -4

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

35n = 15
n=
HELP PLEASE
Answer:
n = 3/7
Step-by-step explanation:
35n = 15
Move all the numbers to one side, and the variables on the other side. We are going to move the 35 to the right side of the equation. To do that, divide both sides by the same term (in this case, 35):
35n/35 = 15/35
We are left with:
n = 15/35
Simplify:
n = 3/7

Hey, sorry this took so long for you to get an answer. Let me try.
Answers:Part A: Answer choice C.
Part B: 6 people can come to the bowling alley.
Explanation:For Part A, I've concluded that the answer is C. Ben can't spend more than $80, so it has to be equal to or less than 80. The flat fee is $45, and the cost per person is variable, $5.50p, so I combined all of those together and got 45+5.50p ≤ 80 .
This is answer choice C.
And for Part B, I got 6. I got this answer from doing 80, the maximum cost, minus the flat rate, 45. Then, I divided this number by 5.50 to get the number of friends that could be paid for. I originally got 6.3636... but I rounded down because you can't have 0.3636... of a friend to come to the bowling alley.
Hopefully this isn't too late. Good luck.

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
