3x/10= 1290
Mutiply by 10 for both sides
3x/10*10= 1290*10
Cross out 10 and 10 , divide by 10 and then becomes 3x
3x=12900
divide by 3 for both sides
3x/3= 12900/3
Cross out 3 and 3 , divide by 3 and then becomes x
x= 4300
Answer: x= 4300
Answer:
y=2.5x+6
Step-by-step explanation:
y= weight
6 is the weight that the baby is born so you would add it to the end making it the b
5 pounds every 2 months so 2.5 pounds every 1 month.
To solve for the mass of a substance is to simply get the
product of volume and density, that is:
mass = density * volume
So calculating for mass:
mass = (2.76 g / cm^3) * 6 cm^3
<span>mass = 16.56 g</span>
K - 2k = 15 + 1 + 6k - 2
-k = (15 + 1 - 2) + 6k
-k = 14 + 6k |subtract 6k from both sides
-7k = 14 |divide both sides by (-7)
k = -2
