We have the following system:
y = -2x + 5
3x-4y = 2
Substituting y in equation 2 we have:
3x-4 (-2x + 5) = 2
We clear x:
3x + 8x - 20 = 2
11x = 2 + 20
x = 22/11
x = 2
Then, we substitute x = 2 in equation 1:
y = -2 (2) +5
y = -4 + 5
y = 1
Answer:
The solution to the system of equations is:
x = 2
y = 1
Answer:
I believe the answer is 40 degrees
Step-by-step explanation:
they are vertical angles which mean they are equal
Mass over volume g/mL: so it would be 5mL as tge volume and 2 g/mL as the density.
The answer is 'Proportional' because 24/33 reduced all the way is 8/11
Answer:
The 5 ounce bottle is $0.98 per ounce
The 15 ounce bottle is $0.69 per ounce
The 15 ounce bottle is a better deal because the cost per ounce is lower
Step-by-step explanation:
To find the cost per ounce for each bottle, divide the cost by how many ounces are in the bottle.
4.89 ÷ 5 = 0.978
10.29 ÷ 15 = 0.686
So, the 5 ounce bottle is $0.98 per ounce, while the 15 ounce bottle is $0.69 per ounce.
The 15 ounce bottle is a better deal because the price is lower per ounce.
