Solve for x.
.9x=9*1 Divide both sides by .9
x=

=10
You would get 10.00 euros.
You can also think of it in this way, that you just move the decimal point over one to the left to get 10.
Answer:
y = - 2x² - 2x + 40
Step-by-step explanation:
Standard form of a quadratic is y = ax² + bx + c : a ≠ 0
Given
y = - 2(x + 5)(x - 4) ← expand factors using FOIL
= - 2(x² - 4x + 5x - 20)
= - 2(x² + x - 20) ← distribute parenthesis by - 2
= - 2x² - 2x + 40 ← in standard form
Answer:
i can't see anything
Step-by-step explanation:
Answer:
w=14
Step-by-step explanation:
-8(w + 1) = -5(w + 10)
Remove the parentheses
-8w-8+-5w-50
Move terms
-8w+5w=-50+8
Collect like terms and calculate
-3w=-42
Then divide on both sides
100
Why:
125-25 is 100
25-25 is 0 so it’ll give you 100
