First you would find the difference of 210 and 46, so 210-46=164.
Then you will divide the solution by the total number of students, so
164 divided by 210.
164/210= about .780 or 78%
Answer:
x=2, perimeter=14
Step-by-step explanation:
Finding x
(x+1)(x+2)
x^2+2x+x+2=12
x^2+3x-10
x^2-2x+5x-10
x(x-2)5(x-2)
(x+5)(x-2)
x=-5
x=2
Length or Width should be a positve number.
x=2
Perimeter:
3+3+4+4=14
Use inverse proportion ratio: xy=k
(124)(7)=k
k=868 (this is our constant)
now substitute the constant into the inverse proportion ratio knowing the number of workers
28x=868
solve for x by dividing both sides by 28 to find the time it takes to build the house
x=31 days
so it will take 31 days for 28 workers to build the house
A = (1/2) bh for height h
2A = bh
first multiply both sides by 2 then divide both sides by b
Area of triangle = (1/2)bh
A = (1/2)bh
2A = bh
h = 2A/b
110 = 1/2(11)h
110 = 5.5h
110/5.5 = 20
The answer Is H = 20
Hope this helps (:
Answer:
X=6
Step-by-step explanation:
isolate the variable by dividing <em>each side</em> <u>by factors </u>that dont contain the variable.
