It’s B because they both equal each other I would explain more but I’m in class but the answer is definitely B
Answer:
x = 5
y = 1
Step-by-step explanation:
So move 2y from the second equation to the other side of the equals sign
2x +3y = 13
x = 3 + 2y
From here substitute X into the first equation
2(3 + 2y) + 3y = 13
Distribute
6 + 4y +3y = 13
Combine like terms and solve for y
7y = 7
y = 1
insert result into the original equation.
x-2(1) = 3
x - 2 = 3
x = 5
insert into other equation to check work
2(5) + 3(1) = 13
10 + 3 = 13 correct
The answer would be 340 and its correct because I did it!!
Answer:
dh = 3 *dV / 130
Step-by-step explanation:
Given:
- volume of punch in bottle = 65 ounce
- volume of punch = v
- increase in height of punch level on dispenser = 1.5 in
Find:
- The change in height of punch in the dispenser in inches, Δh, in terms of the change in the volume of punch in the dispenser in ounces, Δv.
Solution:
We will assume a linear relationship between the increase in punch level dispenser and the increase in volume of dispenser.
h(v) = m*v + h
Where, m is change of height with respect to volume. Hence,
m = dh / dV = 1.5 / 65 = 3 / 130 in / ounce
Hence,
dh = 3 *dV / 130
