Answer:
-5 + -4 = -9
Step-by-step explanation:
-5 + -4 = -9
Start at 0.
You will need to move 5 spaces to the left (Negative numbers move to the left while positives go right).
And -4. Move 4 spaces left again. There you land at -9.
The plus sign is just to combine -5 and -4 together.
Thus the answer is:
-5 + -4 is -9.
Here’s why the other equations aren’t correct.
The first equation says “5 + 4 = 9”.
To represent this, you would move 5 spaces to the right (because the number is posititve.)
Then combine 4. Which you move 4 spaces to the right again. This leaves you at 9 instead of -9.
The second equation says “-5 + -9 = -14”.
To represent this, you would move 5 spaces to the left.
Then move 9 spaces to the left again. Which leaves you at -14.
Your final destination should be -9. Not anywhere else.

Answer: 360
Step-by-step explanation:
1/5 of 600 is 120
Since we have to take 3/5 we simply multiply 120 by 3 to get 3/5
Thus meaning that the answer is 360 apples.
Answer:
580 cm^2
Step-by-step explanation:
First, find the area of the front and back. 20*10=200
There are 2 sides with 20*10 ( front and back) so we can multiply by 2. 200*2=400
Then, the sides. 3*20=60*2=120
Then, the top and bottom 10*3=30*2=60
400+120+60=580
Answer:
Step-by-step explanation:
2p/2 = 2x+7
1) 2x+7 -x - 5 =
width = x + 2
2) 2p/2 = 21 in
x + 5 + x + 2 = 21
2x = 14
x = 7
lenght = 7 + 5 = 12 in
width = 7 + 2 = 9 in
3 )
A = (x+5)(x+2)
4)
A = 12 x 9 = 108
