<span>-1 + n=8(n+6)
Use distributive property
-1 + n= 8n + 48
Subtract n from both sides
-1= 7n + 48
Subtract 48 from both sides
-49= 7n
Divide 7 on both sides so that the only thing remaining on the right sides is the varible n.
Final Answer: -7 = n</span>
Answer:
a)45º
b)22º
c)22º
Step-by-step explanation:
Add Angle b and angle a (45+113) then subtract from 180º (because that is the total of all triangle angles) and you get 22º
Answer:
Step-by-step explanation:
height of monument = 555 feet
Scale in/ft = 1 /25
So, 25 feet = 1 inch
1 feet = 1 /25 inch
555 feet = 555 /25 = 22.2 inch
It means that the height of monument is 22.2 inch on scale. As it is a decimal number so it is not a reasonable scale.
Answer:
1 person
Step-by-step explanation:
It is given that a farmer wants 5 persons to complete a work of clearing his field in ten number of days.
We have to find out the number of persons required if the farmer needs to clear his field in 2 number of days.
Therefore according to the information given :
10 days = 5 persons
∴ 1 day = 
persons
So 2 days = 
persons
person
= 1 person
We can start off by knowing that perimeter is all the sides added together. That means that (2 1/2 x 2) + ((2 1/2 + x) x 2) = 19.
It would be easier to make this into decimals. 2 1/2 is the same as 2.5. Multiply this by 2 and you get 5.
Now you can do 19 - 5 = 14.
This means the other 2 sides have to equal 14 so you write an equation.
2(2.5 + x) = 14.
When you simplify, you get 5 + 2x = 14.
Subtract 5 from both sides and you get 2x = 9.
Solve for x and you get x = 4.5.
Your answer is x = 4.5
