Zach time of reading every weekend forms a sequence with these terms: 10, 20, 40, 80. On the other hand, that of Victoria forms a sequence with terms: 35, 50, 65, 80. By keenly observing the sequences, Zach's sequence is a geometric sequence with a common ratio equal to 2 and Victoria's sequence is an arithmetic or linear sequence with a common difference of 15. Thus, the answer is letter B.
1 gallon = 3.785 liters
3.5 * 3.785 = 13.2475 total liters
1 liter = 1000 milliliters
13.2475 * 1000 = 13,247.5 milliliters
Answer is B
X is sugar
y is butter
z is total money
$0.80x + $1.25y = z
the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.
We will use substitution to solve this system of linear equations, as the first equation has x and y with no coefficients, which makes it easier to find one in terms of the other. We can then substitute that value in the other equation and find the values of x and y.
x = y + 5 ---> equation 1
3x + 2y = 5 ---> equation 2
From equation 1, we get the value of x as y + 5. Using the substitution method, we can find the value of y by substituting (y+5) for x in the 2nd equation.
3(y+5) + 2y = 5
3y + 15 + 2y = 5
5y = 5 - 15
5y = -10
y = -2
Subsituting this value of y in (y+5), we can find x.
x = y + 5
x = -2 + 5
x = 3
Therefore, x = 3 and y = -2.
I will also solve this using elimination method.
Let us multiply equation 1 by 2, so that we get 2y in both equations.
2x = 2y + 10
3x + 2y = 5
Let us add both the equations.
2x + 3x + 2y = 5 + 2y + 10
5x = 15 + 2y - 2y
5x = 15
x = 3
Substituting this value of x in equation 1, we get
x = y + 5
3 = y + 5
y = 3 - 5
y = -2
Therefore, x = 3 and y = -2.

Greetings!</h2>
Answer:
f(x) = 34 + 25w
Step-by-step explanation:
First, we need to find the amount he was paid over the 35 weeks:
909 - 34 = 875
35w = 875
w = 875 / 35 = 25
So every week he is paid $25
The function has to start with 34, as that is the amount already in there, and as w is multiplying by 25, this can be written as 25w
So put these two together:
f(x) = 34 + 25w
