QveST [7]2 years ago

Answer:

x = 40

Step-by-step explanation:

Sum of interior angle of an n-polygon = (n - 2)*180

The polygon given is pentagon with 5 sides.

Sum of the polygon = (5 - 2)*180 = 540°

Therefore, sum of all its interior angles would be:

5x + 150 + (3x - 30) + 70 + (2x - 50) = 540°

Solve for x

5x + 150 + 3x - 30 + 70 + 2x - 50 = 540

Collect like terms

5x + 3x + 2x + 150 - 30 + 70 - 59 = 540

10x + 140 = 540

10x = 540 - 140 (Subtraction property of equality)

10x = 400

x = 400/10 (division property of equality)

x = 40

Which value of y mAkes the equation below true. 3y+8-7y=11
victus00 [196]
We have
3y+8-7y=11
First, we can combine like terms 3y and -7y to get -4y.
Then, we have-4y+8=11 We could then subtract 8 on both sides to get -4y=3
Finally,  we isolate y completely by dividing both sides by -4, to get
y=- \frac{3}{4}

△ABC is similar to △DEF .<br><br> AB=5 inches, BC=9 inches, and DE=7.5 inches.<br><br> What is EF ?
Vikki [24]
Similar triangles have corresponding sides with proportional lengths.

AB/BC = DE/EF

5/9 = 7.5/EF

5(EF) = 9 * 7.5

5(EF) = 67.5

EF = 13.5

What is the net change in how many bags are on the shelf from
Temka [501]

Answer:

-2

Step-by-step explanation:

The computation of net change from the beginning of Tuesday to the end of Monday is shown below:-

The change at the last of Tuesday

Change = Restock - Sales

= 6 - 5

= 1

Here it indicates that the number of bags is rise by 1

The change at the last of Wednesday

Change = Restock - Sales

= 12 - 8

= 4

Here it indicates that the number of bags is rise by 4

The change at the last of Thursday

Change = Restock - Sales

= 12 - 2

= 10

Here it indicates that the number of bags is rise by 10

The change at the last of Friday

Change = Restock - Sales

= 18 - 19

= -1

Here it indicates that the number of bags is fall by -1

The change at the last of Saturday

Change = Restock - Sales

= 24 - 22

= 2

Here it indicates that the number of bags is rise by 2

The change at the last of Sunday

Change = Restock - Sales

= 0 - 15

= -15

Here it indicates that the number of bags is fall by -15

The change at the last of Monday

Change = Restock - Sales

= 0 - 3

= -3

Here it indicates that the number of bags is fall by -3

According to the given situation, it is equivalent the algebraic sum of every change

So,

Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)

Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)

Simplifying: 17 - 19 = -2

To make it easy we can multiply 5 and 0.8 times 10 before we start dividing. The result will no change because we multiplying both numbers by the same number.
5*10=50
0.8*10=8
No we can divide 50:8
  6,25 - its the result
50:8
48
