Jb, this is the solution:
If T = (x + 3, y + 1),
T3 = 3(x + 3, y + 1)
T3 = 3x + 9, 3y + 3
The correct answer is C.
He rode 6 rides times some number that cost 19.56, therefore
6x =19.56
Solve for x to find what the cost is or in this case the value of proportion.
X=3.26
Yesterday = $9.70
Today = $9.81
% Increase = ((9.81 - 9.70) / 9.70) * 100%
= (0.11/9.70) * 100%
≈ 0.0113 * 100%
≈ 1.13 %
≈ 1.1 %<span> to the nearest tenth.</span>
Answer:
Hotdog: $1.50
Hamburger: $3.25
Step-by-step explanation:
<em>You write down the 2 equations based off of the information as I did:</em>
Let x = cost of a hotdog
Let y = cost of a hamburger
<em>and so:</em>
<em />
3x + 2y = 11
2x + 4y = 16
<em />
<em>Now, we need to find x and y:</em>
<em>We will make both equations equal to y to compare them to each other.</em>
2y = 11 - 3x
y = 5.5 - 1.5x
4y = 16 - 2x
y = 4 - 0.5x
4 - 0.5x = 5.5 - 1.5x
x = $1.5
<em>Now plugging in x into the equation:</em>
2(1.5) + 4y = 16
3 + 4y = 16
4y = 13
y = $3.25
And so hotdog = $1.5 and hamburger = $3.25
