Answer:
B) Triangle 2
Step-by-step explanation:
Triangle 2 is rotated and in the counterclockwise direction.
Here are the equations that are represented by the scenarios:
4x + 2y = $14 (Joe)
3x + y = $9 (Becca) or y = 9 - 3x
To find the cost of each burger and fry you will solve the second equation for y and substitute it in for the y in the first equation. This will put everything in terms of x, the price of a fry.
4x + 2(9 - 3x) = $14
4x + 18 - 6x = 14
-2x +18 = 14
-18 -18
<u>-2x</u> = <u>-4</u>
-2 -2
x = 2
Fry cost $2, and burgers cost (9 - 3 x 2) or $3.
Answer:
10/63
Step-by-step explanation:
no common factors between 2 & 9
no common factors between 5 & 7
thus no simplification at the end
5*2 / 7*9 = 10/63
Answer:
3 hours
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s ----> the speed in mph
d -----> the distance in miles
t ----> the time in hours
x ----> distance traveled by Daisy to the meeting point
60-x ----> distance traveled by Sally to the meeting point
so

Solve for d

<em>Distance traveled by Daisy to the meeting point</em>

we have

substitute
----> equation A
<em>Distance traveled by Sally to the meeting point</em>

we have

substitute
----> equation B
substitute equation A in equation B

solve for t
