Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Answer:
24
Step by-step explanation:
6x=3x-1+13
common like terms (-1+13)
6x=3x+12
subtract 3x on both sides
3x=12
divide 3x on both sides
x=4
insert 4 into equation 6*4=24
3(4)-1+13=24
Answer:
$1.12
Step-by-step explanation:
12÷3=4
1 box of markers is $2.50, Multiply $2.50 by 3 and you get $7.50. 12- $7.50= $4.50. $4.50÷ 2= $2.25. $2.25÷2= $1.12
Not 100% but i'm pretty sure this is the answer. Hope this helps. ( if i'm wrong sorry its 2:30 am)
