C would equal -3 because you are going up 9 units
Answer:
x = Ø
Step-by-step explanation:
7x - 12 - 3x = 2(2x + 5)
4x - 12 = 4x + 10
4x = 4x + 22
0x = 22
x = Ø
Hope this helps dude
Counting in 10s is faster than counting in ones because counting in 10s gets you to larger numbers faster because you are going by larger numbers.
Answer:
$3 and $2
Step-by-step explanation:
let p represent popcorn and d drinks , then
2p + 3d = 12 → (1)
3p + 5d = 19 → (2)
multiplying (1) by 3 and (2) by - 2 and adding will eliminate p
6p + 9d = 36 → (3)
- 6p - 10d = - 38 → (4)
add (3) and (4) term by term to eliminate p
0 - d = - 2
- d = - 2 ( multiply both sides by - 1 )
d = 2
substitute d = 2 into either of the 2 equations and solve for p
substituting into (1)
2p + 3(2) = 12
2p + 6 = 12 ( subtract 6 from both sides )
2p = 6 ( divide both sides by 2 )
p = 3
Popcorn costs $3 and a drink costs $2
Solve:
(3x-2)^2-4x(2x-3)>=0
(3x-2)(3x-2)-8x^2+12x>=0
9x^2-12x+4-8x^2+12x>=0
The solution: x^2+4>=0
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
