Answer:
1/8
Step-by-step explanation:
1/4 = 2/8 so 3/8 - 2/8 = 1/8
1 pizza should cost $5.65
Pizza is $5.65 then bottle of coke is $2.45
3 pizzas and coke: ($5.65*3) + $2.45 = $19.4
I solved this by setting up and solving a system of linear equations:
Variables: p = pizza, c = coke
p = c+3.2
3p+c = 19.4
Solve by substitution
3(c+3.2) + c = 19.4
4c+9.6 = 19.4
c = 2.45
Re-plug in:
p = 2.45+3.2
p = 5.65
Step-by-step explanation:
9x2= 3 • 3 • x2
6x= 3 • 2 • x
12x= 2 • 2 • 3 • x
8= 2 • 2 • 2
-46 + x = 25
x = 25 + 46 = 71
Answer:
x = 120
Step-by-step explanation:
just do the reciprocal
140/ 7/6 to get 120 as x
