The solution to the inequality 5x-3(x+1)<7 is x<5.
Step-by-step explanation:
Given inequality is;
5x-3(x+1)<7
Solving the inequality
Adding 3 on both sides both sides of inequality
Dividing both sides of inequality by 2
The solution to the inequality 5x-3(x+1)<7 is x<5.

Answer:
Step-by-step explanation:
a) The two populations were i) the pregnant mothers who took the drug ii) the pregnant mothers who did not take the drugs
b) The data must have been obtained in a survey because experiment was not done.
c) 63 out of 3980 developed abnormalities in I case.
Hence out of 1000 abnormalities estimated =
i.e. approximately 16
d) Mothers who did not take drug
(information incomplete)
e) Medical hypothesis testing requires accurate results and hence sample sizes should be very large.
<em>Complete Question:</em>
<em>You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year. </em>
<em>The initial heights are shown. </em>
Write a system of linear equations that represents this situation.
Answer:
Step-by-step explanation:
Given
Spruce Tree (s):
(yearly)
Hemlock Tree (h):
(yearly)
Required
Represent as system of linear equations
Let the number of years be x.
In both cases, the equation can be formed using:
For Spruce Tree (s):
For Hemlock Tree (h):
<em>Hence, the equations are </em><em> and </em>
