Answer:
a taco is 1.25 and a drink is 0.95
Step-by-step explanation:
tacos = t
drinks = d
5t + 3d = 9.10
3t + d = 4.70
this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get
t = 1.25 and d=0.95
one drink is $0.95
one taco is $1.25

Answer:
Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is 0) - Parallel lines always have the same slope
<u>1) Determine the slope (m)</u>
First, we must organize this given equation in slope-intercept form. This will help us identify its slope.
Subtract 3x from both sides
Divide both sides by 2
Now, we can identify clearly that 
is in the place of <em>m</em> in , making it the slope. Because parallel lines have the same slope, this makes the slope of the line we're currently solving for as well. Plug this number into :
<u>2) Determine the y-intercept (b)</u>
Plug in the given point (8,-11) and solve for b
Add 12 to both sides
Therefore, the y-intercept of the line is 1. Plug this back into :
I hope this helps!
Answer: 1 : -5x + 3y = 2 Equation 2 : -5x - 5y = -30 Because both equations the system of equations by elimination.
