Answer:
3 1/2 small pizzas
Step-by-step explanation:
1/5 = 1 pizza
7/10 = x pizza
7/10 = 3.5/5
3.5/5 = 3.5 pizzas
<em>5x + 2y = 25;</em>
<em>5x + 2y = 25;5x - y = 10;</em>
5x + 2y = 25;
5x = 10 + y;
(10 + y) + 2y = 25;
5x = 10 + y;
10 + 3y = 25;
5x = 10 + y;
3y = 15;
5x = 10 + y;
y = 5;
5x = 10 + y;
y = 5;
5x = 10 + 5;
y = 5;
5x = 15;
y = 5;
x = 3.
