Simplify this expression

– (3x + 9 – 2x)

Answer: 47/100

Step-by-step explanation: I converted 2/10 to 20/100 and then i subtracted 20 from 67 and got 47 and my answer was 47/100.

Step-by-step explanation:

[tex]0.2 + x = 0.67 \\ x = 0.67 - 0.2 = 0.47 \\ = \frac{47}{100} [/tex]

Answer:

C) how the South consistently votes Democratic

Step-by-step explanation:

If you look at the key Blue is democrats.

Then we look at the bottom of the graph where it say south.

From there we can see how they vote.

We can see which is more.

I hope this helped and have a blessed day.

Answer:

A. 38 degrees

Step-by-step explanation:

That entire angle is supplementary meaning it will add up to 180 degrees. So we are given 52 and 90 because of the right angle. Those together come to 142 then subtract that from 180 and get 38 degrees.

Answer:

-12

Step-by-step explanation:

-12=-4^2- -4

Answer:

20

Step-by-step explanation:

I put it into a graphing calculator

and If u put -4 in for x u get:

-4^2= 16

g(-4)= 16 - (-4)

g(-4)= 20 bc 16 minus a negative 4 is a positive 20

hope this helps <3

Answer:

Yes! This is my area!

Step-by-step explanation:

Minimum= 51

Maximum=64

To find the median put the numbers in order

51,53,55,58,60,60,64

no cross off one by one to get the middle number

you end up with 58

first quartile is the upper half so that would be 53

third quartile is the lower half so that wou;d be 60

Hope this helps!

Answer:

D

Step-by-step explanation:

when you put them in numerical order, you have 51, 53, 55, 56, 58, 60, 60, 60, 64

the minimum is the smallest number in the data set. the maximum is the largest number in the data set.

the median is the measure of center, which indicates the middle number in the data set

the first quartile is the center of the bottom set of the data

the third quartile is the center of the upper set of the data

(the upper and lower sets are indicated by which side of the median they are on)

hope this helped :)

Answer:

I have the answers, we did this homework.

Answer:

system of equations

Step-by-step explanation:

x-y=14

x = 2y+3

x - y = 14

x -2y = 3

x - y = 14

-x + 2y = -3

y = 11

x = 25

Step-by-step explanation:

Answer:

-3 & -5

Step-by-step explanation:

let the two numbers be x and y

x + y = -8. sum of the numbers is -8

x - y = 2. difference(-) of the numbers is 2

now we add the two equations

x + x + y - y= -8 + 2

2x = -6

x = -6/2. = -3

substitute value of x in second equation to get y

-3 - y = 2

-y = 2 + 3

-y = 5

y = -5

Answer:

18

Step-by-step explanation:

All I did was count the lines on the coordinate grid between -12 and 6. I was counting by 2's because the grid itself is counting by 2's

========================================================

Explanation:

If you start at 6, and count the number of spaces to get to -12, you should count out 18 spaces.

Or you could start at -12 and move to 6 to move 18 spaces to the right. Keep in mind each tickmark represents 2 spaces.

--------------

You could also think of it like this:

Place point A at -12, B at 0, C at 6

The distance from A to B is 12 units. The distance from B to C is 6 units. In total we have AB+BC = 12+6 = 18 units from A to C.

----------------

Or you could use absolute value and subtraction

Let P = -12 and Q = 6

We could say

|P - Q| = |-12-6| = |-18| = 18

or

|Q - P| = |6 - (-12)| = |6 + 12| = |18| = 18

The order of subtraction doesn't matter as long as you apply absolute value. Absolute value represents distance from 0 on a number line, so absolute value is never negative.

Answer:

578

Step-by-step explanation:

118 + 560 = 678

678 - 100 = 578

578 is your answer

Answer:

578

Step-by-step explanation:

Add 18 to 560 and you get 578. Reason why is because they subtracted 18 from 118 and now you got to add it to 560. Hope that made sense

Answer:

There are 4 crickets left

Step-by-step explanation:

10/2=5

20% of 5 is 1

5-1=4

Don't forget to brainliest me

Answer:

4 crickets

Step-by-step explanation:

On the first day, the lizard ate 50% of the 10 crickets it was given. 50% of 10 is 5 (10 times 0.5), so five crickets remain. The next day, the lizard ate 20% of the 5 remaining crickets. 20% of 5 is 1 (5 times 0.2), and 5-1=4, so 4 crickets are left.

the formula for the circumference of a circle is pi time diameter.

Answer:

422[tex]cm^2[/tex]

Step-by-step explanation:

1. Approach

This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.

2.Find the surface area of the first figure

The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).

(5) * (10) = (50)

(5) * (7) = (35)

(7) * (10) = (70)

Now add thee value together,

(50) + (35) + (70)

= (155)

Double the result,

(155) * (2) = (310)

3. Find the surface area of the other figure

Now repeat the process that was used to find the surface area of the other figure for this figure.

(8) * (4) = (32)

(4) * (3) = (12)

(8) * (3) = (24)

Add the results,

(32) + (12) + (24) = (68)

Double the value,

(68) * (2) = (136)

3. Now subtract the repeated side

Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.

(310) + (136) = (446)

(446) - ((2)*(4)*(3))

= (446) - (24)

= (422)

Step-by-step explanation:

Square= bh

Square= 2×2=

half-circle = 1/2Pi*r×r

half-circle 2 = 1/2Pi*r×r

We would put 1/2 for the half-circle because its half of a circle. And we square it because where finding area. The middle is square, and the two up top is half a circle. Hope that helps :D
