If m∠EBA = x + 7 and m∠EBF = 3x - 1, find x.
Answer:
x = 21
Step-by-step explanation:
ABF is a right angle and m∠EBA + m∠EBF = m∠ABF
3x - 1 + x + 7 = 90 add like terms
4x + 6 = 90 subtract 6 from both sides
4x = 84 divide both sides by 4
x = 21

Answer:
JH = 15
Step-by-step explanation:
KJ = 10
KI = 14
IH = 11
JH = ?
In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:
JH = JI + 11
In order to find JI, we need to subtract KJ from KI. Here's the equation:
14(KI) - 10(KJ) = JI
14 - 10 = 4
JI = 4
Now we plug in the numbers from our first equation:
JH = JI + 11
JH = 4 + 11
JH = 15
Answer:
JH= 15Step-by-step explanation:
Let KJ= 10, KI= 14, and IH= 11KI - KJ = J14 - 10 = 4J + IH = JH4 + 11 = 15[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]

Keith reads 48 chapters of a book in 6 hours.
What is his rate in chapters per hour?
Answer:
Keith's rate in chapters per hour is 8.
Step-by-step explanation:
Divide his 48 chapters by the 6 hours he read and in total it will be a ratio of 8 chapters to one hour.
Keith's rate in chapters per hour will be 8.
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
We are given that Keith reads 48 chapters of a book in 6 hours.
Therefore,
We need to Divide his 48 chapters by the 6 hours he read
48/6
= 8
Hence, in total it will be a ratio of 8 chapters to one hour.

If it takes a fourth of a cup of oil to make 10 cookies, how much oil would it take to make 50 cookies? ?
Answer:
5/4 or 1 1/4 cup of oil
Step-by-step explanation:
Let's make a ratio. 1/4:10. We need to multiply 10 by 5 to get 50 cookies and do the same on the other side of the ratio. 1/4x5=5/4 or 1 1/4 and 10x5 is 50. So our final ratio would be 5/4:50. Hope this helped.
Which statement best defines work?
1. work is the time it takes to move an object once acted upon by a force.
2. work occurs when balanced forces act on a object and cause movement in the direction of these forces.
3. Work occurs when a force causes motion of an object, and this motion is in the same direction of the applied force.
4. Work is the distance over time that an object moves once acted on by a force.

Find n so that mean of the data set is 140. (120, 145, 130, 80, 95, 100, 340, n)
Answer:
Answer: n is 110
Step-by-step explanation:
Formular:
[tex]mean = \frac{ \sum(n_{1}, \: n _{2}, \: ...n_{n} ) }{n} \\ [/tex]
therefore:
[tex]140 = \frac{(120 + 145 + 130 + 80 + 95 + 100 + 340 + n)}{8} \\ \\ (8 \times 140) = 1010 + n \\ 1010 + n = 1120 \\ n = 1120 - 1010 \\ n = 110[/tex]

FIELD TRIP The marching band at Jefferson High School is taking a field trip from Lansing, Michigan, to Detroit, Michigan. The bus driver was
told to stop 53 miles into the trip. If the rest of the trip is 41 miles and the entire journey can be represented by the expression 3x + 16, find the
value of x
Answer:
26
Step-by-step explanation:
The question requires you to find the value of x given the expression and distance
The value of x = 26
Driver's first stoppage = 53 miles
Distance remaining = 41 miles
Total distance = Driver's first stoppage + Distance remaining
= 53 + 41
= 94 miles
Given expression:
3x + 16
If 3x + 16 = 94
Then,
3x = 94 - 16
3x = 78
x = 78 / 3
x = 26

Sally has a photo with a length of 4 and a width of 8 inches. She wants to put a frame around the photo which is the same width all the way around. What is the simplified expression for the area of the framed photo? Recall that A=lw
The simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Length of the photo = 4 inches
Width of the photo = 8 inches
Since, frame around the photo is the same width all the way around.
Therefore, area of the frame of the photo = Length x width
⇒ area of the frame of the photo = 8x4 = 32 square inches
which is the required expression for the area of the frame of the photo.
Thus, the simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.

First of what is the inverse of FX = 2x - 3
Answer: [tex]f^{-1}(x)=\frac{x+3}{2}[/tex]
Step-by-step explanation:
The inverse of an equation is when you switch the x-value with the y-value. The y-value is equal to f(x). So, your work will look something like this. Note the changes in bold.
f(x) = 2x - 3
f(x) = y
y = 2x - 3
x = 2y -3
x + 3 = 2y
[tex]\frac{x+3}{2}[/tex] = y
y = [tex]\frac{x+3}{2}[/tex] (here, I'm just switching it so the y-value is on the left to make it easier to read)
y = f(x)
[tex]f^{-1}[/tex](x) is the notation for inverse f(x)
So, the final equation would be written as
[tex]f^{-1}(x)=\frac{x+3}{2}[/tex]
