At a bake sale, David bought 3 tarts and 5 cookies, and paid $10.50. At the same prices, Lisa bought 4 tarts and 8 cookies, and paid $14.80. What was the price of a tart and the price of a cookie?
Answers
C = Cookies
David:
3T + 5C = 10.50
Lisa:
4T + 8C = 14.80
Setup as system of equations and use substitution or elimination
Elimination is easier for this case but either will give you the right answer I worked it both ways
T= cost of tarts = $2.50
C= cost of cookies = $0.60

You include 1/2 tablespoon of essential oils in a solution for every 12
tablespoons of jojoba oil. What is the value of the ratio of essential oils to
jojoba oil?
Answers
The required ratio of essential oils to jojoba oil is 1:24.
Given that,
You include 1/2 tablespoon of essential oils in a solution for every 12
tablespoons of jojoba oil.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
tablespoon of essential oils = 1/2
tablespoons of jojoba oil = 12
Ratio = [1 / 2] / 12
Ratio = 1 / [2 × 12]
Ratio = 1 / 24
Thus, the required ratio of essential oils to jojoba oil is 1:24.

Which system of linear equations has the ordered pair (-2,8) as its solution?
Oy - 2x = 12 and x - 2y = -18
O x – 2y = 12 and y - 2x = -18
Oy + 2x = 12 and x + 2y = -18
O x + 2y = 12 and y + 2x = -18
Answers
Answer:
The solution to the system of linear equations is:
(x, y) = (-2, 8)
Hence, y - 2x = 12 and x - 2y = -18 has the ordered pair (-2,8) as its solution. Thus, option A is correct.
Step-by-step explanation:
Checking the first system of equations
y - 2x = 12
x - 2y = -18
solving the first system of equations
[tex]\begin{bmatrix}y-2x=12\\ x-2y=-18\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}y-2x=12\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y-4x=24[/tex]
[tex]\begin{bmatrix}2y-4x=24\\ -2y+x=-18\end{bmatrix}[/tex]
adding the equations
[tex]-2y+x=-18[/tex]
[tex]+[/tex]
[tex]\underline{2y-4x=24}[/tex]
[tex]-3x=6[/tex]
[tex]\begin{bmatrix}2y-4x=24\\ -3x=6\end{bmatrix}[/tex]
solving -3x=6 for x
[tex]-3x=6[/tex]
Divide both sides by -3
[tex]\frac{-3x}{-3}=\frac{6}{-3}[/tex]
Simplify
[tex]x=-2[/tex]
[tex]\mathrm{For\:}2y-4x=24\mathrm{\:plug\:in\:}x=-2[/tex]
[tex]2y-4\left(-2\right)=24[/tex]
[tex]2y+8=24[/tex]
Subtract 8 from both sides
[tex]2y+8-8=24-8[/tex]
Simplify
[tex]2y=16[/tex]
Divide both sides by 2
[tex]\frac{2y}{2}=\frac{16}{2}[/tex]
Simplify
[tex]y=8[/tex]
Therefore, the solution to the system of linear equations is:
(x, y) = (-2, 8)
Hence, y - 2x = 12 and x - 2y = -18 has the ordered pair (-2,8) as its solution. Thus, option A is correct.
