Answer: 3x+5
Step-by-step explanation:
3x+75/15=
1/15x(45x+75)=
1/15x15(3x+5)=
3x+5
The first step is to distribute:
(10n-6) + (10-35n)
Second step is to combine like terms:
(25n+4)
Answer: (25n+4)
Answer:
y=-2x
Step-by-step explanation:
The function has the table:
x f(x)
-3 -6
-2 -4
-1 -2
0 0
Looking at the table, f(x) deceases by 2 each time. This is a constant rate of change called slope. This is a linear function and its equation can be written using y = mx+b. m = -2. b is the y-intercept for starting point where x = 0. When x=0, the table shows y=0. So b=0.
This means the rule is y = -2x.
Answer:
<h2>
7/8 gallons of Ginger ale </h2>
Step-by-step explanation:
Total gallons of punch mixture = gallons of pineapple juice + orange juice + gallons of apple juice + gallons of Ginger ale
Given gallons of pineapple juice = 3/4 gallons
Orange juice = 1 1/2 gallons
Gallons of apple juice = 7/8
Total gallons of punch = 4 gallons
On substituting into the formula above:
4 = 
]
gallons of ginger ale = 
gallons ginger ale = 
She needs 7/8 gallons of Ginger ale to make the total of 4 gallons of punch
Answer:
Q2 2010
Step-by-step explanation:
Let the number of quarters = x
Samsung increases by 6 each quarter.
Apple decreases by 1 each quarter.
Samsung
L = a + (x - 1)*6
a = 1
L = 1 + (x - 1)*6
Apple
L = a - (x - 1)*1
a = 53
L = 53 - (x - 1)*1
Now the problem is how many quarters go by until they meet?
1 + (x - 1)*6 = 53 - (x - 1) Remove the brackets
1 + 6x - 6 = 53 - x + 1 Combine like terms on both sides.
-5 + 6x = 54 - x Add 5 to both sides
6x = 59 - x Add x to both sides
7x = 59
x = 59/7 = 8 3/7
So sometime in the 8th quarter from zero they will be equal. At the end of the quarter, Samsung will be greater than Apple
So the answer should be 4 quarters from Q2 2009 or Q2 2010
