Answer:
System of Equations:
let x be the cost of a taco
let y be the cost of a burrito
7x + 3y = 22
3x + y = 8
The cost of a taco is $1
The cost of a burrito is $5
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Draw out and you'll see if make a triangle. Use Pythagorean theorem
you are given c and the other side
So,
c2 = a2 + b2
20^2 = 12^2 + b2
400 = 144 +b2
256 = b2
b = 16
Hope this helps
If you use the addition property of equality, what number would you add to both sides of the equal sign to isolate the variable?
You would subtract 5/7 from both sides of the equation
What is the solution?
x = 26/7 or 3 and 5/7
x + 5/7 = 31/7
Subtract 5/7 from both sides of the equation:
x + 5/7 - 5/7 = 31/7 - 5/7
x = 26/7
Answer:
(-9, 9)
Step-by-step explanation:
Each coordinate is multiplied by the scale factor.
B' = 3B
B' = 3(-3, 3)
B' = (-9, 9)
