Answer:
$1.75
Step-by-step explanation:
1 pound of carrot and 1.5 pounds of squash cost $7.00.
1c + 1.5s = 7 ----------------- [ 1 ]
4.5 pounds of carrot and 1.75 pound of squash cost $14.00.
4.5c + 1.75s = 14 ----------------- [ 2 ]
<u>[ 1 ] x 4.5:</u>
4.5c + 6.75s = 31.5 ----------------- [ 1a ]
<u>[1a] - [2]:</u>
5s = 17.5
s = $3.50
<u>Sub s = 3.5 into [ 1 ]:</u>
1c + 1.5 (3.5) = 7
1c + 5.25 = 7
1c = $1.75
3x^2-16x=x^2-30
-x^2 -x^2
2x^2-16x=-30
+30 +30
2x^2-16x+30=0
2x-6=0 or x-5=0
x=3 or x=5
A. 3,5

Answer:
1. 247 mg ÷ 10 = 24.7 cg
2. 247 mg ÷ 100 = 2.47 dg
247 mg ÷ 1000 = 0.247 g
Step-by-step explanation:
1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.
2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.
3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.
