2/7=0.285714
3/7=0.428571
4/7=0.571428
5/7=0.714285
6/7=0.857142
Step-by-step explanation:
1/7 = 0.142857
2/7=2(1/7)
2/7=2(0.142857)
3/7=1/7+2/7
3/7=0.142857+0.285714
Or
3/7=3(1/7)
3/7=3(0.142857)
4/7=2(2/7)
4/7=2(0.285714)
5/7=5(1/7)
5/7=5(0.142857)
6/7=2(3/7)
6/7=2(0.428571)
f(-3) =17
f(x)=2x^2-1
Let x = -3
f(-3)=2(-3)^2-1
= 2(9) -1
= 18-1
17
The number of pizzas sold during A- lunch is 64
Let us solve the question using the ratio method
∵ The ratio of pizza to nachos sold during A-lunch is 4 to 3
∵ There were 48 nachos sold
→ By using the ratio method
→ Pizza : Nachos
→ 4 : 3
→ x : 48
→ use the cross multiplication
∵ x × 3 = 4 × 48
∴ 3x = 192
→ Divide both sides by 3
∵ =
∴ x = 64
∴ The number of pizzas sold during A- lunch is 64
