5x-8 is the the answer simplified
Answer:
and 
Step-by-step explanation:
We have the following system of equations:
and 
To solve the problem, we need to equal the two equations:
⇒ 
⇒ 
⇒ 
So you need to find two numbers that added equal to 5 and multiplied equal to 4. These two numbers are 
and 
.
Then, the factorized form of the polynomial is: 
.
The, the solution to the system of equations is: and .

D
Step-by-step explanation:
7x + 28 < 84
- 28 -28
7x < 56
÷7 ÷7
x < 8
If it was a negative 7 the arrow would change direction
Answer:
P [ K > 3.95] = 0.5633
Step-by-step explanation:
The interpretation of the given question goes thus;
Suppose that K is a random variable
P[-3.95 ≤ K ≤ 3.95] = 0.725
where; P [ + 3.95 < K ] = P [K < - 3.95]
P[K< 3.95] - P [K > - 3.95] =0.725
P [K < 3.95] - [ 1- P[K < 3.95]] = 0.725
P[k < 3.95] - 1 + P [ K < 3.95] = 0.725
3.95 P [ K < 3.95] -1 = 0.725
3.95 P [ K < 3.95] = 1.725
P [ K < 3.95] = 1.725/3.95
P [ K < 3.95] = 0.4367
P [ K > 3.95] = 1 - P[K< 3.95]
P [ K > 3.95] = 1 - 0.4367
P [ K > 3.95] = 0.5633
Answer:
129 1/6 feet
Step-by-step explanation:
Formula for area is L*W
1. convert the mixed numbers to improper fractions
12 1/2 feet = 25/2
10 1/3 feet = 31/3
2. multiply numerator by numerator (25*31 = 775
3. multiply denominator by denominator (2*3=6
4. convert improper fraction 775/6 into a mixed number by dividing 775 by 6.
5. 775/6 = 129 r. 1 or 129 and 1/6
