Answer: D. 3y + 5 − 7y = 4(-y + 1) + 5
Step-by-step explanation:
Original equation:
3y + 5 - 7y = 4(-y+1) + 5
Group like terms on the left of the equal sign and distribute on the right side of equal sign:
-4y + 5 = (-4y +4) + 5
Simplify:
-4y + 5 = -4y +9
Subtract 5 from both sides:
-4y = -4y + 4
Add 4y to both sides:
0 = 4
0 CANNOT equal 4 therefore, this equation has no solution.
Step-by-step explanation:
(q and (not q or p)) = (q and not q) or (q and p) = false or q and p = q and p
(p and not (q and p)) = (p and (not q or not p)) =
= (p and not q) or (p and not p) = (p and not q) or false =
= p and not q
so, we have in total
(q and p) or (p and not q) = (p and q) or (p and not q).
this is p, because if p=false both brackets are false and therefore the whole expression is false. and if p=true, then one of the 2 brackets must be true, which makes the whole expression true.
Answer:
19.8
Step-by-step explanation:
You have to first put the numbers into ascending order:
8.4, 9.3, 11.4, 18.5, 19.6, 20, 26.1, 32.3, 44.1, 46.41.
Because there is an even amount of numbers, you end up with 19.6 and 20.
The in between of 19.6 and 20 is 19.8.
(You can work this out by adding the two numbers together and then dividing by two if you have to.)
Answer:
24.9 repeating in
Step-by-step explanation:
![\sqrt[3]{15,625}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B15%2C625%7D)
= 24.9 repeating.
Basically, just find the cube root of 15,625. Since, the object is a cube, the volume formula is V=
. Just undo the by finding the cube root. Hope this helps!!
