14 times 0.999 blank 14
probably it is a relation symbol
=
>
<
<u>>
<</u>
so we know that x times 1=x
therefor
x times (less than 1)<x
0.999 is less than 1
0.999<1
therefor
14 times 0.999<14
blank is <
Answer:
12s +8i=108 and s+i=10 are the answers
Step-by-step explanation:
For any direct variation, the equation is of the form y = kx, where k is the constant of proportionality.
Given the equation: f = 2.5w
The constant of proportionality is 2.5.
This means that the ration of the cups of flour to the cups of water used in the recipe is 2.5
Answer:
x = 10 and x = -2
Step-by-step explanation:
The equation has 2 solutions because we have a square. When things are squares, we get a positive and negative solution.
(x-4)^2 - 28 = 8
Add 28 to each side
(x-4)^2 - 28+28 = 8+28
(x-4)^2 = 36
Take the square root of each side
sqrt((x-4)^2) = ±sqrt(36)
x-4 = ±6
Add 4 to each side
x-4+4 = 4 ±6
x = 4 ±6
x = 4+6 and x = 4-6
x = 10 and x = -2
