Answer:
First expression 8y +4x +10
Second expression 7x-3y +6
If you want to combine both expressions: 5y +11x +16
Step-by-step explanation:
Like terms are the terms which have same variables and powers/roots.
Example: 7x and 2x are like terms because the variables are both "x". So we can combine in 9x
In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same
10y + 3x + 10 + x -2y
10y-2y=8y 3x+x=4x
so 8y +4x +10
3x - y + 4x + 6 - 2y
3x+4x=7x -2y -y = -3y
so 7x-3y +6
Answer:
0.5
Step-by-step explanation:
The probability that the first mouse turns left and the second mouse turns right is 0.5 × 0.5 = 0.25.
The probability that the first mouse turns right and the second mouse turns left is 0.5 × 0.5 = 0.25.
So the probability that only one mouse turns left is:
P = 0.25 + 0.25
P = 0.5
Another way of looking at it: the probability that only one mouse turns left is 1 minus the probability that both turn left or both turn right.
P = 1 − (P(both left) + P(both right))
P = 1 − (0.5 × 0.5 + 0.5 × 0.5)
P = 0.5
13x-8+7x+4+3x
Combine like terms
23x-4
It can only be simplified. Without an equal sign (=), x cannot be found.
