1.75 divided by 3 = 0.5833
So 20 x 0.5833 = 11.66
The answer is $11.66 for 20 oranges
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
Answer:
e.29 d.1
Step-by-step explanation:
we will replace with the values we have :
- 300 that's a big number . Obviously it isn't a solution
- 50 : 30+50 = 80>60 so no
- 45: 30+45= 75 >60 so no
- 30+30 = 60 we have < not ≤ so no
- 1 yes . it's obvious
- 29 +30 = 59<60 so yes !
