Step-by-step explanation:
⅔ (x – 7) = -2
Let's start by getting rid of the fraction. Multiply both sides by 3.
2 (x – 7) = -6
Distribute the 2:
2x – 14 = -6
Add 14 to both sides:
2x = 8
Divide both sides by 2:
x = 4
Answer:
P = (13h+k+6m) cm
Step-by-step explanation:
Given that,
The side lengths of a triangle are :
(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm
We need to find the perimeter of the triangle.
We know that,
Perimeter = sum of all sides
So,
P = (4h + 2k)+(9h + 4m)+(2m - k)
= (4h+9h)+(2k-k)+(4m+2m)
= 13h+k+6m
Hence, the perimeter of the triangle is (13h+k+6m) cm.
Answer: there is no sufficient evidence
Step-by-step explanation: We need to perform an hypothesis test on the average gram setting on the machine before we can draw out a conclusion.
We need the sample mean, either of population or sample standard deviation and sample size to perform the test.
None of these parameters was given to us, hence we don't have enough sufficient evidence to prove the statement.
