Answer:
2x^2-6x-4
Step-by-step explanation:
(7x2 + 4x - 9)
-(5x2 + 10x - 5)
=
7x^2-5x^2=2x^2
4x-10x=-6x
-9-(-5)=-4
thus, your answer is 2x^2-6x-4
Answer:
-0.8 or 991/10
(also it can be 10%)
Step-by-step explanation:
991
——— = 99.10000
10
Step by step solution :
Step 1 :
9
Simplify ——
10
Equation at the end of step 1 :
9
100 - ——
10
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 10 as the denominator :
100 100 • 10
100 = ——— = ————————
1 10
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
100 • 10 - (9) 991
—————————————— = ———
10 10
Final result :
991
——— = 99.10000
10
Answer:
18
Step-by-step explanation:
half of 36 is 18
so you would have an improper fraction and then turn it into 2
