Answer:
Step-by-step explanation:
Let the number be x
5 times a number = 5x
24 - 5x = 15
-5x = 15-24
-5x = -9
x= -9/-5
x = 9/5

or x = 1.8
Answer:
The expression -10 - (-4) represents the given diagram.
Step-by-step explanation:
Here, the total number of blue boxes marked with (-) = 10
So, in Total number of (-) are 10 x (-1) = -10
Now, the number of boxes crossed out = 4
So, the total value crossed out = 4 x ( Value on each box) = 4 ( -1) = -4
⇒ The value Left after crossing = Total value - The crossed out value
= -10 - (-4)
Hence, the expression -10 - (-4) represents the given diagram.
