Answer:
30 small pretzels were sold that night.
Step-by-step explanation:
x = small pretzels
y = large pretzels
x + y = 50
2x + 4.5y = 150
x + y - y = 50 - y
x = 50 - y
2(50 - y) + 4.5y = 150
100 - 2y + 4.5y = 150
2.5y = 50
------- -----
2.5 2.5
y = 20
x + 20 = 50
x + 20 - 20 = 50 - 20
x = 30
What is the first step to solving a system of linear equations algebraically?
Step-by-step explanation:
Hey there!
Given;
[A = 1/2b*h]
Divide both sides by 'h'.
A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].
Multiply '2' and 'A'.
A*2/h = b
b = 2A/h.
