How do you do this problem ?5y 9≤4?

Answers

Answer 1
Answer:

The solution to inequality is,

⇒ y ≤ - 1

We have to give that,

An inequality to solve,

5y + 9 ≤ 4

Now, Simplify the inequality as,

⇒ 5y + 9 ≤ 4

Subtract 9 on both sides,

⇒ 5y + 9 - 9 ≤ 4 - 9

⇒ 5y ≤ - 5

⇒ y ≤ - 5/5

⇒ y ≤ - 1

Therefore, The solution is,

⇒ y ≤ - 1

Answer 2
Answer: 5y+9≤4
minus 9 both sides
5y+9-9≤4-9
5y+0≤-5
5y≤-5
divdie both sides by 5
y≤-1

At a country concert, the ratio of the number of boys to the number of girls is 2:7. If there are 250 more girls than boys, how many boys are at the concert?

Answers

Boys : Girls = 2:7
let the no. of boys be x
so no of girls = 250+x
so, x:(250+x) = 2:7
x/(250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100
