3x/8 + 6 = 5x/8 3x/8 + 6x8/8 _ this makes the denominator 8 = 5x/8 3x/8 + 48/8 = 5x/8 (Since all the denominators are the same we can just cross them out) 3x + 48 + 5x 48 = 5x - 3x 48 = 2x 48/2= 24 x=24 x + 6 =30 ( since we didnt add the 6 we just
If so, first square both sides, which would leave you: (2-y)(2-y)=y+4 FOIL 4-4y+y^2=y+4 Then subtract 4 and y which would get you y^2-5y=0 Factor out the y. y(y-5)=0 y=0 or y=5
What do you want done?? Do you want it solved for y?
Set up a proportion and solve: x/5=29.4/28 5.25 feet
a^3-2a^2/2a^2-4a a^2(a-2)/2a(a-2) Reduces to a/2
O my, x=60, not 6.. My fault for overlooking that. The three sides would be, 60 120 182 *Sorry again
To find perimeter, you add up all the sides. So, your equation would be: x+2x+3x+2=362 Combine like terms: 6x+2=362 Solve to get x by itself by subtracting 2. 6x=360 Divide by 6 x=6 To find each side, substitute 6 in for x for each of the expressions, x,
X^2-13x+6x=0 x^2-7x=0 x(x-7)=0 x=0 or x=7
The answer is 0.8 gallons when rounded to the nearest 10th.
3x^2+5x^2-x-7x^2=0 8x^2-x-7x^2=0 1x^2-x=0 x(x-1)=0 x=0, 1
First find the volume of the large juice can. Since the can is a cylinder, you would use the formula: V=pir^2h V=(3.14)(3^2)(10) V=(3.14)(9)(10) V=282.6 Divide 231/282.6 to get 0.817 gallons
Set x and (x-2) both equal to 0. Your answer would be: x=0, 2
Substitute 2x for x into the function, which would leave you: h(x)=(2x)^2-2x Factor out a 2x. H(x)=2x(x-1) then set 2x and x-1 both equal to 0. 2x=0 x-1=0 x= 0 x=1
