i think of a number double it and add eleven. i get 25
a)use the statement above form an equation use the letter x for the uknown number
b) solve the equation
Answers
Answer:
Answer= 7
Step-by-step explanation:
the unknown number being, x, .
i think of a number ( x), double it, ( 2× x)= 2x, and add 11 to be ( 2x + 11), i get 25.
So, the equation will be:
2x + 11 = 25.
to solve it, take (+11) to the equals side and it will change to (-11), or in other words, subtract 11 on both sides.
the equation will thus remain to be:
2x = 25-11
2x = 14.................Divide both sides by 2 to remain with x
so, X = 7.

Answer:
∠a= 65°, ∠b= 115°, ∠c= 25°
Step-by-step explanation:
The sum of the angles in a triangle is 180°. This is abbreviated to '∠ sum of ∆'.
∠c +55° +60° +40°= 180° (∠ sum of ∆PQR)
∠c +155°= 180°
∠c= 180° -155°
∠c= 25°
∠a +60° +55°= 180° (∠ sum of ∆PQS)
∠a +115°= 180°
∠a= 180° -115°
∠a= 65°
The sum of the angles on a straight line is 180°. It's abbreviation is 'adj. ∠s on a str. line'.
∠b +∠a= 180° (adj. ∠s on a str. line)
∠b +65°= 180°
∠b= 180° -65°
∠b= 115°

How many complete rotations does the minute hand of a clock make as it moves from 12:00 noon to 4:00 p.m.? rotations
Answers
Answer:
60 x 4 = 240 times
Step-by-step explanation:
In every hour there are 60 minutes.
That means for every hour the minute hand moves 60 times
Take the amount of hours and times it by 60 ( Hours x 60 )
The minute hand of the clock completes 4 rotations as it moves from 12:00 noon to 4:00 p.m
What is complete rotation of minute hand ?In a clock there are second hand, minute hand and hour hand, all rotates anticlockwise. If the minute hand come at the same place after start rotating from that place , then the rotation is called one complete rotation.
Since 1 complete rotation of a minute hand takes 60 minutes, which is one hour.
Therefore, In one hour the minute hand completes one rotation.
Thus, after first complete rotation of minute hand the time will be 1:00 p.m.
After two complete rotation of minute hand the time will be 2:00 p.m.
After three complete rotation of minute hand the time will be 3:00 p.m.
Similarly, after four complete rotation of minute hand the time will be 4:00 p.m.
Hence it takes 4 complete rotation of a minute hand to moves from 12:00 noon to 4:00 p.m.

C. 2,450 square feet
D. 2,500 square feet
Answers
Answer:
Correct choice D. 2,500 square feet
Step-by-step explanation:
Area of a rectangle
The area of a rectangle of dimensions x, y is:
A=x.y
The diagram provided in the question is to a scale of 1 inch=16 ft.
We have provided a modified diagram where all the dimensions are also shown in ft.
The longer side of the shape is 4*16=64 ft
The smaller side of the shape is 3*16=48 ft
The bottom side of the store is 2 1/4*16=36 ft
The leftmost side of the store is 1 3/4*16=28 ft
We need to find the value of x and y.
The value of x is x=64 ft - 36 ft = 28 ft
The value of y is y=48 ft - 28 ft = 20 ft
The area of the whole rectangle of dimensions 48 ft and 64 ft is:
[tex]A1=48 ft * 64 ft = 3,072 \ ft^2[/tex]
The area of the small blue rectangle is:
[tex]A2=28 ft * 20 ft = 560\ ft^2[/tex]
The area of the store is:
[tex]As=A1-A2=3,072 \ ft^2- 560\ ft^2=2,512 \ ft^2[/tex]
Rounding to the nearest 50 square feet:

Step-by-step explanation:
To begin this process, we will first select the second equation. Here is how the Substitution method wourks:
[tex]\displaystyle \left \{ {{3x + 5y = 3} \atop {x + 2y = 0}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {x = -2y}} \right. \\ \\ 3[-2y] + 5y = 3 \hookrightarrow -6y + 5y = 3 \hookrightarrow -y = 3; -3 = y, 6 = x \\ \\ \\ \boxed{[6, -3]}[/tex]
So, you substitute [tex]\displaystyle x[/tex]for [tex]\displaystyle -2y[/tex]and continue combining like-terms until you receive the y-value. You then plug this back into the system to get the x-value, which was what you saw.

Your cafeteria line requires 8 minutes on the average for each customer to proceed through the line and pay the cashier. The average time space between each customer is 30 seconds. If the line is open for 14 hours for lunch, how many customers can you serve for lunch?
Answers
Answer:
99 customers.
Step-by-step explanation:
Ok so
14 hours = 840 minutes
Each customer requires 8 and a half minutes
8 minutes (to proceed through the line)
and
30 seconds (the interval time in between to get to another customer)
840 minutes ÷ 8.5 = 98.8..
Therefore, you can approximately serve 99 customers in 14 hours.
I didn't simply round that up, but the last customer does not need the 30 seconds of interval so therefore, you would get to serve 99 customers in 14 hours anyway.
