Answer:
$8
Step-by-step explanation:
We can write an equation with the scenario given and solve for what we need, Alberto's weekly allowance.
Let his weekly allowance be "x"
Since he spend HALF of it, he spent 0.5x of it.
He has remaining also 0.5x of it
Now, whatever he has (0.5x), he gets $4 more from cleaning windows. After that he has:
0.5x + 4
This amount is equal to $8, so we can write:
0.5x + 4 = 8
0.5x = 8 - 4
0.5x = 4
x = 8
So, alberto's weekly allowance is $8
Answer:
12 + 4x
Step-by-step explanation:
To solve this you would have to use the distributive property.
The problem would basically go like this.
4 (3+x)
(Distribute)
(4x3) (4 x X)
4x3 = 12, 4 x x = 4x
So the answer would be 12 +4x
Hope this helps :)

Answer:
80.7 because you multiply
Answer:
prime
Step-by-step explanation:
x^2 + 10x – 18
What two numbers multiply to -18 and add to +10
There are no numbers that multiply to -18 and add to 10
-1 *18 = -18 -1 +18 = 17
-2 *9 = -18 -2 +9 = 7
This cannot be factored
