What is the answer 38 + 7k = 8(k + 4)
pls give me an answer not a link so pls this is the last of my points
Answer:
[tex]k=6[/tex]
Step-by-step explanation:
We can distribute the right side to get [tex]38+7k=8k+32[/tex].
We can subtract [tex]7k[/tex] from both sides to get [tex]38=k+32[/tex].
We can subtract [tex]32[/tex] from both sides to get [tex]6=k[/tex].
So, the answer is [tex]\boxed{k=6}[/tex] and we're done!
The solution to the equation 38 + 7k = 8(k + 4) is k = 6.
We can begin by simplifying both sides of the equation in order to find the solution to the equation 38 + 7k = 8(k + 4):
38 + 7k = 8k + 32
Next, we can separate the constant terms from the variable terms by placing them on opposite sides of the equation:
7k - 8k = 32 - 38
Simplifying even more
-k = -6
We can multiply both sides of the equation by -1 to remove the negative sign:
k = 6
Hence K = 6 is the answer to the equation 38 + 7k = 8(k + 4).

Samirs bedroom has an area of 48 square feet.

Answer: 2 feet
Step-by-step explanation:
Susan and Jim both babysit. Susan earns $15 for 2 hours and $30 for 4 hours. Jim’s charges are calculated using the equation t=7h+10 (t is the total and h is the hours) which statement is true
A.) Jim charges $7.00/hour, which is higher than Susan’s hourly rate
B.) Jim charges $10.00/hour, which is higher than Susan’s hourly rate
C.) Susan charges $7.00, which is equal to Jim’s hourly rate
D.) Susan charges $7.50, which is higher than Jim’s hourly rate
Please answer as soon a possible
Answer:
D.
Step-by-step explanation:
7h is the amount of money Jim makes per hour. You can find the amount of money Susan makes by dividing the amount she made to the hours:
15/2 = 7.50
Susan charges $7.50, which is higher than Jim's hourly rate. which is the correct answer would be a statement (D)
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
To find the hourly rate for Jim, you can plug in different values for h (the number of hours) in the equation t = 7h + 10 and solve for t (the total). For example, if h = 1, then t = 7(1) + 10 = 17. This means that if Jim babysits for 1 hour, he charges $17.
If you divide the total amount that Jim charges by the number of hours he works, you get his hourly rate. In this case, the hourly rate is t/h = 17/1 = $17/hour.
To find Susan's hourly rate, you can divide the total amount that she charges by the number of hours she works. For example, if Susan babysits for 2 hours, she charges $15, so her hourly rate is $15/2 = $7.50/hour. If Susan babysits for 4 hours, she charges $30, so her hourly rate is $30/4 = $7.50/hour.
Since Susan charges $7.50/hour, which is higher than Jim's hourly rate of $17/hour, the correct statement is D.) Susan charges $7.50, which is higher than Jim's hourly rate.

A line passes through the points (-5, 2) and (10.-1). Which is the equation of the line?
Answer:
y= -1/5x + 1
Step-by-step explanation:
When looking for a line between two points, you want to use the following formula: (y2-y1)/(x2-x1) which finds your distance between points for the y and x coordinate to solve for your slope. y1 is the y coordinate from the first given point and x1 is the x coordinate from the first given point as well. this would go the same for x2 and y2 for the second given equation.
Next, we plug in our values so that we get (-1-2)/(10-(-5)). This will then lead us with -3/15 which simplifies to -1/5. This is our slope. Now that we have our slope we can rule out every option except the first for the answer. However, if we want to look for the entire answer we need to plug in one of our given values in the formula we have: y=-1/5x.
So to find the y-intercept, we can plug in any of the given coordinates so we can fo (10,-1) so that -1=-1/5(10)+b (b what added because we are putting the equation in slope-intercept, therefore we need to find the value b.) So we are left with -1=-2+b now we want to isolate b by adding 2 on both sides to cancel -2 and get 1=b. This would leave us with the equation y=-1/5x+1.
