M = milk
C= cheese
X=meat
milk = 0.5c
meat = 4c
cheese = 1c
<span>4 +0.5 = 1c = 5.5c</span>
C= 42/5.5 = 7.64
X = 7.64 x 4 = 30.56
M =7.64 * 0.5 = 4.67
30.56 + 3.82 + 7.64 = approximately $42
Hello here is a solution :
<span> |x + 2| < 5
-5</span>< x+2<5
-5-2 < x+2-2 <5-2
-7<x<3
<span>interval notation : open (-7) ; open(3)</span>
They need 18 more teachers.
Set the problem up as a ratio.
3 x
---- = -------
70 14,700
70 x = 44,100
x = 630
The district already has 612 teachers. So, 630 - 612 = 18 more needed.
1 beehive produces 85 lb/year
10³ beehives = 1,000 beehives produce 85x1,000 = 85,000 lb/year
