Solve the inequality 1/2y>5

y > 10

Step-by-step explanation:

1/2y>5

Multiply each side by 2

2* 1/2y>5*2

y > 10

y > 10

Step-by-step explanation:

Inequality:

1/2y>5

We need to isolate the variable y.

Since it is being multiplied by 1/2, we need to multiply by the reciprocal, or opposite, on both sides. The reciprocal of 1/2 is 2. (Check by multiplying both numbers and making sure the product is 1.)

Multiply:

1/2y>5

x2     x2

y > 10

Therefore, the simplified inequality is y > 10.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
