Answer:
the cost of 3 apples and 7 oranges be £15 and £35 respectively
Step-by-step explanation:
Let us assume the apple be x
And, the oranges be y
Now according to the question
5x + 4y = £45
And,
2x + 8y = £50
Multiply by 2 in equation 1
So,
10x + 8y = £90
2x + 8y = £50
8x = £40
x = £5
And, y be
5(£5) + 4y = £45
£25 + 4y = £45
4y = 20
y = £5
So, the cost of 3 apples and 7 oranges be £15 and £35 respectively
(m-21) (m+1)there I thinks it's right unless I messed up my work
Y= -2x+3
-2 is the slope which is given, and 3 is the y intercept which is also given, so plug those numbers in y=Mx+b to make your equation
Answer:It has to be more clear
Step-by-step explanation:
You cannot express 108/250 in a whole number but it can be simplified to 54/125
