Answer:
The total number of women (w)=800
Step-by-step explanation:
We can express the total number of each group as follows;
Total number of people (p)=Number of Adults (a)+number of children (c)
2,500=a+c....equation 1
Number of Adults (a)=4×number of children (c)
a=4 c....equation 2
Replacing the value of a in equation 1 with the value for a in equation 2
2,500=4 c+c
5 c=2,500
c=2,500/5
c=500
Number of children (c)=500
Replace the value of c in equation 2 with 500 and solve
a=4×500
a=2,000
Number of adults (a)=2,000
But the total number of adults can be expressed as;
Total number of adults (a)=Total number of men (m)+total number of women (w)
a=m+w
where;
a=2,000
m=1,200
replacing;
2,000=1,200+w
w=2,000-1,200
w=800
The total number of women (w)=800

Answer:
surface area=602.88 in^2+
Step-by-step explanation:
top & bottom:
6^2 x Pi x2=36 x 3.14x2=226.08 in^2
vertical side:
circumference X height
2(6)(Pi)x10=2(6)(3.14)(10)=376.8 in^2
376.8+226.08=602.88 in^2
surface area=602.88 in^2
In an equation like that, y would double into 2y. But just keep in mind that what happens to one side must happen to another.
Answer:
-1
Step-by-step explanation:
2x-10
-------------- = 3x
4
Multiply each side by 4
2x-10
4*-------------- = 3x*4
4
2x-10 = 12x
Subtract 2x from each side
2x-10 -2x = 12x-2x
-10 = 10x
Divide each side by 10
-10/10 =10x/10
-1 =x
