Answer:
q = 36/7 or 5 1/7
Step-by-step explanation:
q · 7/9 = 4
Multiply each side by 9/7
q · 7/9 *9/7 = 4*9/7
q = 36/7
If we want it as a mixed number instead of an improper fraction
7 goes into 36 5 times with 1 left over
q = 5 1/7
The system of equations that model the situation is:
4c + 2s+ 3b == $29.51
c + 4s + 2b = $21.83
2c + 5s = $21.93
<h3>What are simultaneous equations?</h3>
Simultaneous equations are more than one equation that would have to be solved jointlu in order to determine the required values.
Methods of solving simultaneous equations are:
- Elimination method
- Graph method
- Substitution method

Answer:
There is enough evidence to support the attorney’s claim
Step-by-step explanation:
Given that one attorney claims that more than 25% of all the lawyers in Boston advertise for their business.
Sample size n =200
Sample proportion = 
Hypotheses:
(right tailed testat 5% significance level)
Assuming H0 to be true, std error of p = 
Test statistic z = p diff/std error
= 
p value for one tailed =0.0170
Since p <0.05 we reject null hypothesis
There is enough evidence to support the attorney’s claim
