Answer:
multiply 2,550 gallons to 30 and you will have your answer
To get from 7-10=2(-3+8) to 7-10=-6+16, you have to use the distributive property because of the parenthesis. the next step would be adding 10 to both sides in order to even the equation (adding because it cancels out the negative and makes 0), and the last step you have is adding 6 to both sides of the equation to balance it. in order to get 2, you have to divide 26 by 13 (26/13). hope this helps!
Answer:
[1] = 6
x = -3/2 is the root
Step-by-step explanation:
A perfect square trinomial is of the form ...
(a + b)² = a² +2ab +b²
You have ...
- a²=16w² ⇒ a = 4w
- b² = 36 ⇒ b = 6
- 2ab = 2(4w)(6) = 48w
Then the factorization is ...
16w² +48w +36 = (4w +6)²
This will be zero when x = -6/4 = -3/2.
Answer:
12.5%
Step-by-step explanation:
The spinner has 8 equal sections, numbered 1, 2, 3, 4, 5, 6, 7, and 8. The only number greater than 7 is 8. There is 1 number greater than 7.
P(greater than 7) =
1
8
Write your answer as a decimal. Then convert your answer to a percentage.
1
8
= 0.125 = 12.5%
P(greater than 7) = 12.5%
