10x + (-8)= -3x + 2 How do I solve this in pemda order

larisa [96]

Answer:

x= 10/13

Step-by-step explanation:

First, we need to put the variable on one side and the constants on another side.

Also a positive and a negative equal a negative. [this is related to +(-8)]

10x+(-8)= -3x+2

+3x +3x

13x-8=2

+8 +8

13x=10

Finally you divide on both sides

13x/13=10/13

x= 10/13

I hope this is right! I tried my best

Marcus loves baseball and wants to create a home plate for his house. Marcus needs to calculate the area of the home plate at th

Jobisdone [24]

Answer:

Area of the polygon = 59 in²

Explanation:

From the given diagram, we can note that the given polygon is composed of an upper triangle, a side triangle and a rectangle

Therefore:

Area of polygon =

area of upper triangle + area of side triangle + area of rectangle

1- getting the area of the upper triangle:

We have:

base of triangle = 7 in

height of triangle = 6 in

Therefore:

Area of upper triangle = $\frac{1}{2}*base*height = \frac{1}{2}*7*6=21$ in²

2- getting the area of the side triangle:

We have:

base of triangle = 4 in

height of triangle = 5 in

Therefore:

Area of upper triangle = $\frac{1}{2}*base*height = \frac{1}{2}*4*5=10$ in²

3- getting the area of the rectangle:

We have:

length of rectangle = 7 in

width of rectangle = 4 in

Therefore:

Area of rectangle = length x width = 7 x 4 = 28 in²

4- getting the total area of the polygon:

Area of polygon =

area of upper triangle + area of side triangle + area of rectangle

Therefore:

Area of polygon = 21 + 10 + 28 = 59 in²

Hope this helps :)

The ages of the guests on a museum tour are 32, 14, 18, 29, 65, 50, 48, 44, and 28. Find the five-number summary of the ages.

marishachu [46]

Answer:

Minimum = 14 , 1st Q = 23 , median = 32 , 3rd Q = 49 , maximum = 65

Step-by-step explanation:

* Lets explain what is the five-number summary

- The five-number summary for a set of data, are:

# The minimum

# First quartile

# Median

# Third quartile

# The maximum

∵ The ages of the guests are 32 , 14 , 18 , 29 , 65 , 50 , 48 , 44 , 28

# The steps to find them

1. Put your numbers in ascending order

∴ 14 , 18 , 28 , 29 , 32 , 44 , 48 , 50 , 65

2. Find the minimum and maximum for your data

∴ The minimum is 14

∴ The maximum is 65

3. Find the median where the median is the middle number.

∵ There are 9 ages then the middle age is the 5th age

∵ The 5th age is 32

∴ The median is 32

4. The first quartile is the median of the lower half of the data

∵ The lower half of the ages are 14 , 18 , 28 , 29

∵ The numbers of ages are even

∴ The first quartile is the average of the two middle ages

∴ The 1st quartile = (18 + 28)/2 = 23

∴ The 1st quartile is 23

5. The third quartile is the median of the upper half of the data

∵ The upper half of the ages are 44 , 48 , 50 , 65

∵ The numbers of ages are even

∴ The third quartile is the average of the two middle ages

∴ The 3rd quartile = (48 + 50)/2 = 49

∴ The 3rd quartile is 49

* The five-number summary of the ages are:

Minimum = 14 , 1st Q = 23 , median = 32 , 3rd Q = 49 , maximum = 65
