Answer:
On #7.
Step-by-step explanation:
12(3+y)=5(2y+8)=
12y+36=10y+40=
12y-36=10y+40-36=
12y=10y+4=
12y-10y=4
2y=4
2y/2=4/2
y=2
Question 2) 6y - 1 = 5
First we need to add 1 to each side.
6y - 1 + 1 = 5 + 1
6y = 6
Then we will divide each side into 6 groups.
6y/6 = 6/6
y = 1
Question 4) 3t - 1 = 8
First we need to add 1 to each side.
3t - 1 + 1 = 8 + 1
3t = 9
Then we will divide each side into 3 groups.
3t/3 = 9/3
t = 3
Answer:
Area of room = 21 * 16
= 336 m²
Area of Carpet = (21 - 1)* (16-1)
= 20*15
= 300
Area of border = Area of room - Area of carpet
= 336 - 300
<h3>= 36 m².</h3>
Answer and Step-by-step explanation:
Anything that is to the power of 0 is equal to 1. This is why 2 to the power of 0 is equal to 0.
0 is the only number such that for any number x, x + 0 = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.
