Answer:
24
Step-by-step explanation: We have to find out how much centimeters of tape we need to wrap one present, so you have to divide 12 by 3=4
so you need 4 centimeters of tape to wrap one present. Now we have to find out how much tape we need for 6 presents, so we do 4x6=24.
Answer:
Step-by-step explanation:
13. -2(4)= -8 14. 6(-5)= -30 15. 3(-5)(2)= -30
16. -12(4)= -48 17. -4(2)^2= -64 18. (-5)^2= -25
19. -5(-3)(4)= =60 20. 13(-5)(2)= -130. 21. 3(-3)= -9
Hope this helps!
Answer:
Step-by-step explanation:
5. 17.25-8.25= 9
6. 7+8=15
7. 2*8=16 or 2*9=18
Answer:
3.25 pounds
Step-by-step explanation:
x + 4 (1/2) + 3 (1/2) = 11
x + 4.25 + 3.5 = 11
x + 7.75 = 11
x = 11 - 7.75
x = 3.25 pounds
We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
