Dang what grade is that in looks hard i might know the answer
Let x represent the number of minutes and y the cost. Then
y - 0.85 = (1.10 - 0.85)/(10 - 5) (x - 5)
y - 0.85 = 0.25/5 (x - 5) = 1/20 (x - 5) = 1/20 x - 1/4
y = 0.05x - 0.25 + 0.85 = 0.05x + 0.6
y = 0.05x + 0.6
The cost of 25 minutes = 0.05(25) + 0.6 = 1.25 + 0.6 = $1.85
Answer: 2/3 pounds more
Step-by-step explanation:
This week = 2/3 pounds
Last week = 1 1/3 pounds
Difference = 1 1/3 - 2/3
= 4/3 - 2/3
= 4-2/3
= 2/3 pounds more he purchased last week.
Answer:
3x^6+3x^3-18
Step-by-step explanation:
Use the Foil method: (a+b)(c+d)=ac+ad+bc+bd
1. 3x^6+9x^3-6x^3-18
2. Collect like terms 3x^6+(9x^3-6x^3)-18
3. Simplify and that should give you 3x^6+3x^3-18 Hope that helps !
Answer:
D
Step-by-step explanation:
tan(15)= 12/x
tan(15)(x) = 12
x = 12/tan(15)
x = 44.78
