What you want to do is cross multiply so you get 5(x+4)=7(3x+28) then you distrubute the 5 and then you distribute the 5 and the 7 to the number in the parentheses 5x+20=21x+196
subtract 5x on both sides to get 20=16x+196 then you subtract 196 on both sides to get -176=16x last what you want to do is divide 16 on both sides to get x=-11
The answer is B. The shape is staying the exact same, it’s just moving.
The car is worth 17,200.
20,000x .14=2800
20,000-2,800=17,200.
Answer:
do what?
Step-by-step explanation:
Answer:
The confidence interval is 
Step-by-step explanation:
From the question we are told that
The sample mean is 
The standard deviation is 
The sample size is 
given that the confidence level is 85% then the level of significance is mathematically represented as

Next we obtain the critical value of
from the normal distribution table the value is

Generally the margin of error is mathematically represented as

=> 
=> 
The 85% confidence interval is mathematically represented as

=> 
=>
