Answer:
Step-by-step explanation:
x+2×3x=26
Answer: 3
Step-by-step explanation:
Feom the question, we are informed that students are making ornaments and each takes 1/2 of a piece of Bristol board and that they go to the cupboard and find 1 1/2 pieces of Bristol board.
The number of ornaments that they can make will be calculated by dividing 1 1/2 by 1/2. This will be:
= 1 1/2 ÷ 1/2
= 3/2 ÷ 1/2
= 3/2 × 2/1
= 3
They can make 3 ornaments

Step-by-step explanation:
=a^1/x=x√a
(a^1/x) ^b= x√a^b
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
