First you do the numbers in the parentheses (1+2)=3 next you do the number outside of the parentheses 6 divided by 2 =3 so now you have 3 and 3, since you have two answers and there is no mathematic sign there to tell you what to do, you multiply. There for your answer is 9. I hope this helped and gave you a better understanding! ^-^

Ok.... so the first part is asking you what the perimeter of the picture itself is.
The picture is 5in by 7in.... SO you add 5+5+7+7=24.... So the perimeter of the pic is 24 inches.

Now part b

So the frame is one inch thick
This mean that the sides are now 2 inches longeron each side

 SO we have 7+7+9+9=32

So the perimeter is 32

I hope that helped!!!!! If you dont understand something ask and i will reexplain ;)

PLEASE ANSWER ASAP
STatiana [176]

Answer:

2/9 is the correct option.

Step-by-step explanation:

As the spinner is numbered 2, 4 and 5

The general formula for probability :

P(A) = n(A) / n(S)

n(S) is the number of whole states occur in two spins which is 3 × 3 = 9

n(A) is the event that Rico will get a product of 20.

n(A) = 2   ∵ 4 × 5 and 5 × 4 will bring the product 20.

Therefor, the probability that Rico will get a product of 20 when Rico spins the spinner twice will be:

P(A) = n(A) / n(S)

       = 2/9

Therefore, 2/9 is the correct option.

Equation 1: m = 8 + 2n
slava [35]

Answer:

1:×4

m×4=(8+2n)×4

4m=32+8n

now,

1:×4 - 2:

4m-4m = 32+8n -4+4n

0=(32-4) +(8n-4n)

0=28+4n

28=-4n

n= -7

n=-7. 1:,

m=8+2n

m=8+2×(-7)

m=8-14

m=-6
