Answer:

b x 5 = 30

Step-by-step explanation:

This is one of the many correct answers. The reason why is because it shows that the variable is correct. And if you didn’t know what the variable was you could just divide 30 / 5.

Aloiza [94]

Answer:

155.25= 12

Step-by-step explanation:

                 17*1/2 = 12

8 1/2          17/1* 1/2

8*2+1          17*1/1*2  

   2             17*1/1*2

16+1               17/1*2

5(n+1) equals 2 ( n+ 7)
alina1380 [7]
The wording is confusing but I am going to guess it is 5(n+1)=2(n+7).  So 5xn=5n and 5x1=5.  5n+5=2(n+7).  Then 2xn=2n and 2x7=14.  The question now stands 5n+5=2n+14.  Then 5n+2n=7n and 14-5=9.  So, you have 7n=9.  Then you divide both sides by 7 and get n=1.2857...

a pool is being filled with a large water hose. the height of the water in a pool is determined by 7g^2+3g-4. Previously the poo
ArbitrLikvidat [17]

If both the hoses are on the same time then the height of the water in the pool is given by the expression  15g^2 + 5g - 6

Step-by-step explanation:

(7g^2 + 3g - 4) + (8g^2 + 2g - 2)

= (7g^2 + 8g^2) + ( 3g + 2g) + (-4 -2)

with the help of distribution law,

= (7 +8)g^2 + (3 + 2)g - (4 + 2)

= 15g^2 + 5g - 6

Therefore if both the hoses are on the same time then the height of the water in the pool is given by the expression  15g^2 + 5g - 6
