C. 5/6
30 people with soda + 45 people with lemonade = 75/90 people
simplifies to 5/6.
X=3 and y=5. To solve the system algebraically, I think you just have to plug in the answers. I'm not quite sure for (b)
Answer:
Step-by-step explanation:
Givens
4 scones
1 loaf of bread
Total cost = 3.30
Equation
Let the loaf of bread = b
Let the scones = s
Cost = b + 4s
Solution
Substitute the givens into the equation
b + 4s = Cost
90 + 4s = 3.30 Subtract 90 from both sides
90-90 + 4s = 3.30-90 Combine
4s = 2.40 Divide by 4
4s/4 = 2.40/4
s = 0.6 of a pound
Answer: 1 scone = <u>60 pence</u>.
Answer: A
Step-by-step explanation:
It distributed into 5x 4 and 5 x 9. Lemme get brainliest
25000=X [((1-(1+0.078)^(-5))/0.078]
Solve for x
X=6228.44
