Answer:
(4x + 2) x 3
4x + 2 x 3
4x + 6
4x/4 = X + 6/4 = 1.5
X = 1.5 I think
P.S. hope this helped if it is correct may I get Brainliest
The quadrilateral which can be considered as a "Parallelogram" or "Not necessarily a parallelogram. are second and fourth figure.
"The correct figures are (b) and (d)
<h3>What is a parallelogram?</h3>
A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal).
- The first one is a parallelogram because, the angle are shown are alternate interior angles which defined between two parallel lines.
- The second one is not a parallelogram because, the angle are shown are alternate interior angles which should defined between two parallel lines. But there are no parallel lines.
- The third one is not a parallelogram because, the parallelogram have opposite angles are equals not the adjacent angle.
Here the adjacent angle are given equal.
- The fourth one is a parallelogram because, the opposite side of parallelogram are equal and parallel to each other.

Fraction are ratio of two integers. It will take Amen 20 days to do the task alone
<h3>Proporions and fractions</h3>
From the given question, we have the following information
Let the number of days Amen can take to complete a task be x
If Payson is thrice as fast as Amen at completing a task, then the number of das Payson takes will be 3x
If they both pick up a task together, and complete it in 5 days, then;
1/x + 1/3x = 1/5
Find the LCM
3+1/3x = 1/5
4/3x = 1/5
Cross multiply
3x = 20
Determine the time taken by Amen:
x =20/3
This shows that it will take Amen 20 days to do the task alone

Answer:
9 boxes
Step-by-step explanation:
8. To find an average, you add all the numbers together and then divide by how many numbers there are. Since we're trying to find the last number, we'll set up the problem like this:
(72+82+82+x)/4 = 80
Add your numbers: (286+x)/4 = 80
Divide each side by 4: 286+x = 320
Subtract 286 from 320: x = 34
He needs to get a 34 on his last test for an 80 average.
9. We want to find the total of his first 5 scores, so we multiply 100 by 5 to get 500.
Add 118 to 500: 618
Divide by 6 (the new number of bowling scores): 103
His new average is 103.
