Answer:
4
Step-by-step explanation:
Lets make 
be the ? in the equation.
That becomes ( x 3) - 3 = 15.
First you have to add 3 on both sides. After doing that it gets to ( x 3) = 15 - 3.
Then you simplify it to 3 = 12.
Now you divide 3 on both sides. That gets to = 4 after doing it.

Answer:
Step-by-step explanation:
watermelon=w
cantaloupe=c
3w+2c=32 x3 9w+6c=96
4w+3c=44 x2 8w+6c=88
(9w+6c) - (8w+6c) =
96-88=
c=8
canteloupe is 8 pounds
3w+2(8)=32
3w+16=32
3w=16
w=5 1/3 pounds
watermelon is 5 1/3 pounds
2(5 1/3)+8=
10 2/3+8=
18 2/3 pounds
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.
