Answer:
The first choice is the one you want
Step-by-step explanation:
Use geometric means to solve for a first. The formula is
and 64 = 15a and a = 64/15
That one was quite easy. Finding b is a bit more difficult.
The formula for finding b is
Solving for b:
Filling in we have
and
and
so b = 136/15
I believe the answer $7.42. You have to divide 18.02 by 8.5 to get the cost per gallon. Then multiply the cost per gallon by 3.5 to get your answer
The series of numbers that meets the requirements is 5+6+8+9+4+6+7+3+9+2+8+9+1.
<h3>How to check that the series meets the requirements?</h3>
To verify that the series meets the requirements, we must establish what the requirements are:
- Every 3 consecutive numbers must add up to 19.
- In total there must be 14 numbers.
- The total sum of all the numbers must be 77.
To verify that every 3 consecutive numbers add up to 19, we separate them into 4 groups of 3 and one number is left over.
- 5 + 6 + 8 = 19
- 9 + 4 + 6 = 19
- 7 + 3 + 9 = 19
- 2 + 8 + 9 = 19
In total there must be 14 numbers and they must add up to 77.
5+6+8+9+4+6+7+3+9+2+8+9+1 = 77

Answer:
2a + 20b +2xc = 2(a+10b+xc)
Step-by-step explanation:
Let a = one litter box, b = one cat toy and c = a bag of cat food
The 1 litter box = a, 10 cat toys = 10b and x bags of cat food = xc
For one sister, purchase = a + 10b + xc
And for two sisters,
total purchase = 2 x ( a + 10b + xc ) = 2(a+10b+xc)
= 2a + 20b + 2xc
Answer:
Step-by-step explanation:
The given line has equation
The steepness is the absolute value of the slope.
The larger the absolute value of the slope, the greater the steepness.
The steepness of
is
The steepness of
is
Therefore the second line is less steep than the first line.
