Somebody please help me on multiple step equations with parenthesis.
Answers
Answer:
k = 8
Step-by-step explanation:
8(10 - k) = 2k
First, distribute within the parenthesis,
80 - 8k = 2k
Add 8k to both sides of the equation
80 = 10k
Divide both sides by 10 to get your answer
8 = k

Can someone please help me solve this question? 7-3r=r-4(2+r)
Answers
Answer:
There is no solution
Step-by-step explanation:
7−3r=r−4(2+r)
Step 1: Simplify both sides of the equation.
7−3r=r−4(2+r)
7+−3r=r+(−4)(2)+(−4)(r)(Distribute)
7+−3r=r+−8+−4r
−3r+7=(r+−4r)+(−8)(Combine Like Terms)
−3r+7=−3r+−8
−3r+7=−3r−8
Step 2: Add 3r to both sides.
−3r+7+3r=−3r−8+3r
7=−8
Step 3: Subtract 7 from both sides.
7−7=−8−7
0=−15

Answers
Answer:
Total, T = (300s+200b+42d) mg
Step-by-step explanation:
Given that,
Kayson mixes 300 mL spinach, 200 mL of berries, and 42 mL of dressing to make a salad.
There are s mg of vitamin C per mL of spinach, b mg per mL of berries, and d mg per mL of dressing.
In 300 mL of spinach vitamin C is = (300 s)mg
In 200 mL of berries vitamin C is = (200 b)mg
In 42 mL of salad vitamin C is = (42 d)mg
It means that, total mg of vitamin C is :
Total, T = (300s+200b+42d) mg
Hence, this is the required solution.

three consecutive even numbers whose sum is -42
Answers
Answer:
-12, -14, -16
Step-by-step explanation:
x + (x+2) + (x+4) = -42
3x + 6 = -42
Isolate the variable 3x by subtracting 6 from both sides
3x = -48
Then isolate the variable x by dividing 3 from both sides
x = -16
Then add 2 for the 2nd number
Then add 4 for the third number

The manager also states that the number of customers that enter their restaurant is equal to 3 times the number of people that buy a hotdog from the hotdog cart plus 35. What number of people buying a hotdog from the hotdog cart across the street makes the equation 4x+9=3x+35 true? Round your answer to the nearest whole number.
Answers
Answer:
26 customers
Step-by-step explanation:
Represent customers entering as y and those buying hot dogs as x
[tex]y = 4x + 9[/tex]
[tex]y = 3x + 35[/tex]

Determine the number of people buying hotdogs (x)
Substitute 4x + 9 for y in the second equation

if f(x)=2x+1, what would be the first step to find f(1)
Answers
Answer:
First step: plug 1 in for x
f(1)=3
Explanation:
We are given the function
f(x)=2x+1
We want to find f(1). Therefore, the first step would be plugging 1 in for each x.
f(1)=2(1)+1
If we want to find the answer, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Multiply 2 and 1.
f(1)=2+1
Add 2 and 1.
f(1)=3
The first step is plugging 1 in for x. The final answer is f(1)=3
Answer:
We are given a defined function: f(x) = 2x + 1. This function is the same as saying y = 2x + 1 (y and f(x) are used interchangeably and are the same value - just a different way of representing it). Because we want to find f(1), math states that if you replace one variable with a value, you must replace all of the same variables with that value. Because of this, if we change f(x) to f(3x), we are declaring that the variable x has a value of 3x. Or, if we were to change f(g) to f(3g + 4), we would then be replacing the g's in the function with 3g + 4.
Using these examples, we can the find the value of f(1). We would simply replace the x-values in the function with the value of 1 and then take any operations necessary - be sure to use PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
[tex]f(x) = 2x + 1\\\\f(1) = 2(1) + 1\\\\f(1) = 2 + 1\\\\f(1) = 3[/tex]
Therefore, the first step to solve the problem would be to replace the x-values in the equation with the value of 1. From there, you would simplify your equation and find what the value of the function is if evaluated at f(1).

Physics students were modeling the height of a ball once it was dropped from the top of a 10 foot ladder. The
students found that the height, in feet, h, of the ball above the ground as a function of the number of seconds, t, since
it wasdropped was given by h(t) = 10 - 2t^2

notation.

Justify your reasoning for choosing the above boundaries on your domain using the context of the problem.
How would the domain for this function differ if we were looking at it outside of the context of this problem?
Answers
Answer:
Interval notation: [0, 2.236]
Set Builder notation: [tex]\{t\ |\ 0\le t\le 2.236\}[/tex]
Step-by-step explanation:
Given that:
Equation of height of the ball dropped from a height of 10 foot, as:
[tex]h(t) = 10 - 2t^2[/tex]
Where [tex]t[/tex] is the time since the ball was dropped.
To find:
The domain of the function in Interval and set builder notation.
Solution:
Domain of a function is defined as the set of valid input values that can be given to the function for which the function is defined.
Here, input is time.
We can not have negative values for time.
Therefore, starting value for time will be 0 seconds.
And the value of height can not be lesser than that of 0 ft.
[tex]0= 10 - 2t^2\\\Rightarrow 2t^2=10\\\Rightarrow t^2=5\\\Rightarrow t =2.236\ seconds[/tex]
Maximum value for time can be 2.236 seconds.
Therefore the domain is:
Interval notation: [0, 2.236]
Set Builder notation: [tex]\{t\ |\ 0\le t\le 2.236\}[/tex]
