If you are solving for a: it equals 3
distribute: 5a + 5=2a +14
get rid of extra number on one side: 5a=2a +9 (subtract 5 from both sides)
get rid of the other variable: 3a=9 (subtract 2a from both sides)
divide to isolate a: 3a/3=9/3 (divide by three on both sides)
answer= a=3
Answer
5
Step-by-step explanation:
if you replace the 55 with a 9 you get 5
The answer would be the second one because of the 45-45-90 Right Triangle rule. If the side lengths are the same the the hypotenuse is just the square root of that number.
Answer:
30 + 3
Step-by-step explanation:
We are multiplying 5 and x.
5*x
=5*6
=30
The y is alone.
y
=3
Let's solve it.
30 + 3 = 33.
x=6
y=3

Answer:
0.0445937
Step-by-step explanation:
-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.
-Assuming normal distribution, the test statistic is calculated as:
-we then find the p-value of the test statistic from the z-tables:
P-value=0.0445937
