Answer:
x = 4/5
Step-by-step explanation:
Group like terms together. Start by subtracting 1 from both sides, obtaining
5x = -4 + 10x.
Then combine the x terms, obtaining 4 = 5x.
Solving for x by dividing both sides by 5, we get x = 4/5.
There could be 35 toffees in the box.
it’s basically just any number that can be multiplied with another to get a new expression
Answer:
AECG
Step-by-step explanation:
1
sqrt(49) = 7
sqrt(a^2) = a
sqrt(b^2) = b
For every two variables you can take one out from under the root sign and thorough the other one away.
Answer: E
2
sqrt(36) = 6
sqrt(a^2) = a See comment for 1.
b must be left where it is. There is only 1 of them.
6asqrt(b)
Answer: A
3. sqrt(25) = 5
sqrt(b^2) = b
a must be left alone. There's only 1 of them.
5b sqrt(a)
answer: C
4
sqrt(81 a b)
sqrt(81) = 9
The variables must be left alone. There's only1 of them
9 sqrt(ab)
Answer G
