Put y in the x+2y-6. x+2(3x-7)=0. So x+6x-14=0. 7x-14=0. 7x=14. x=2
That the answer 76 because you do 19/25x?/100 so the ?=76
The correct answer is C) 800,000 cubic meters.
The scale given is for the length, width or height of the model. In order to find the scale for the volume, we would cube this scale, since volume is a cubic measurement:
(1/200)³ = 1/8,000,000
Since the volume of the model is 0.1, we multiply this by 8,000,000 to find the volume of the actual dam:
0.1(8000000) = 800,000
Answer:
x= 20 x =-5
Step-by-step explanation:
x^2 – 15x – 100 = 0.
What two numbers multiply to -100 and add to -15
-20 * 5 = -100
-20 +5 = -15
(x-20) (x+5) =0
Using the zero product property
x-20 =0 x+5 = 0
x= 20 x =-5
It is A. 6.9 x 10^5 Because
