The new expression is 4.8d - 4.2c
<u>Explanation:</u>
<u />
Given:
Expression = (-7c + 8d) 0.6
On multiplication we get:
-4.2c + 4.8d
Therefore, the new expression is 4.8d - 4.2c
She would have a total of 40 stamps.
Answer:
256
Step-by-step explanation:
1st : 2nd = 8 : 7 -------- (1)
Number of 2nd year students = 224
Number of 1st year students = ?
From equ. 1,
1st : 2nd = 1st : 224 = 8 : 7
Therefore,
1st / 224 = 8 / 7
1st = 8 * 224 / 7
Therefore, Number of 1st year students = 256
