The sum of three numbers is 85. The second is 7 more than the first. The third is 2 more than four times the second. Find the nu
9966 [12]
Let x=the first number
Then x+7=second number
And 4(x+7)+2=third number (2 more than 4 times the second)
Now we are told that:
x+(x+7)+(4(x+7)+2)=85 get rid of parentheses
x+x+7+4x+28+2=85 simplify
6x+37=85 subtract 37 from each side
6x+37-37=85-37
6x=48
x=8---first number
x+7=8+7=15 second number
4(x+7)+2=4*15+2=62 third number

8+15+62=85

What is the solution set for -4x - 10 ≤ 2?
hichkok12 [17]

Answer:

x <u>></u> -3

Step-by-step explanation:

- 4x - 10 <u><</u> 2

     + 10 <u><</u> + 10

<u>- 4x < 12</u>

-4      -4

x <u>></u> -3

I think the sign flips because the negative sign is w/the X.... If it doesn't, sorry 4 being wrong...
