Compare these rational numbers. Which of the following are true?

Answer:

8a - 7

Step-by-step explanation:

First, subtract 12a from 20a

20a - 12a

= 8a

Now, subtract -3 from -10.

Subtracting a negative number is the same as adding a positive number, so add 3 to -10.

-10 + 3

= -7

Put together 8a and -7

8a - 7

So, the simplified expression is 8a - 7

Answer:Amount of rice cooked by Alice =2 11/24kg

Together  Alice and Jasmine cooked 4 7/24kg of rice

Step-by-step explanation:

Amount of rice cooked by Jasmine =1 5/6 kg

Amount of rice cooked by Alice = 5/8 kg more than Jasmine

=1 5/6 kg+ 5/8 kg

=1 (20 +15) /24

=1 35/24

=1 +1 11/24

= 2 11/24 kg

Together  Alice and Jasmine cooked 1 5/6 kg + 2 11/24kg =

=3 20 +11/24

=3 31/24=3 +1 7/24

=4 7/24kg

Answer:

Angle 0 is 6.28/3. or 2.093.

Step-by-step explanation:

Pie is an irrational number, so it will be repeating forever. A simple way to get pie is just 3.14. 3.14 times 2 is 6.28. Divide 6.28 by 3 to get 2.093 repeating, but simplified is 2.093.

Answer:

x = -5

Step-by-step explanation:

Multiply each x and 3 by -4, obtaining

-4x - 12 = 8

Now solve for x by combining the constants:

-4x = 20, or

x = -5

Answer: x=-5

Step-by-step explanation: distribute the -4 first to both x and 3

-4x-12 = 8 then add 12 to both sides to isolate x

-4x= 20

divide by -4 and you get  x= -5

check it

-4(-5+3)

-4(-5)= 20 (a negative times a negative makes a positive)

then -4(3)= -12

20-12= 8

it checks out, hope this helps ^_^

Answer:

(4+4) = 8 (1+1) = 2 then 8 x 2 = 16

so your answer is 16

Step-by-step explanation:

you can use PEMDAS to solve equations like this

Answer:

(4+4)*(1+1)

following the PEMDAS order of operations:-

calculate within the parentheses:-

Now, calculate within the parentheses (1+1)

Multiply:-

our final answer is 16

Step-by-step explanation:

Answer:

z^2+14z+49

Step-by-step explanation:

=(z+7)(z+7)

=(z)(z)+(z)(7)+(7)(z)+(7)(7)

=z^2+7z+7z+49

=z^2+14z+49

Answer:

c(x) = 5^(x-3) + 2

Step-by-step explanation:

shifting up affects the y axis value

shifting sideways affects the x axis value

when we shift up, we gain value and it is positive, if we shift sideways; to the left, we are losing value and we have to subtract from the x value

So we have our equation as;

c(x) = 5^(x-3) + 2

Answer:

LM > MK > KL

Step-by-step explanation:

Given: ΔKLM , m∠K = 101° , m∠L = 67°

By definition of a triangle's sum of interior angles, the ∑ΔKLM's interior angles is 180°, ∴ m∠M = 180 - (101 + 67) = 12°

By the usage of law of sines, the opposite side's measurement is contingent with the angle measurement. The smaller the angle measurement, the shorter the opposite side.

Note the angles:

m∠M = 12° ∴ Side LK = shortest

m∠K = 101° ∴ Side ML = longest

m∠L = 67° ∴ Side KM = in between

∴ LK < KM < ML

A) LM > MK > KL is your answer.

Answer:

The two numbers are 18 and 42

Step-by-step explanation:

let the two numbers = x  and y

Their sum:    x + y = 60 ------ (1)

Also, dividing the larger by the smaller (partition = 2 and remainder = 6).

Let the larger number = y

[tex]\frac{y}{x} = 2\frac{6}{x} \\\\\frac{y}{x} = \frac{2x +6}{x} \\\\y = 2x + 6\ \ ----(2)[/tex]

Substitute the value of y into equation (1)

x + (2x + 6) = 60

x + 2x + 6 = 60

3x  +  6 = 60

3x = 60  - 6

3x = 54

x = 54 / 3

x = 18

y = 2x + 6

y = 2(18) + 6

y = 36 + 6

y = 42

The two numbers are 18 and 42

Answer:

18

Answer:

20% decrease

Step-by-step explanation:

Below are the steps that we will follow:

Now, lets apply it to the problem:

Starting Value: 465 students

Final value: 372 students

Let's do step #1:

465-372 = 93

Now, let's do step #2:

93/465 = 0.2

Now, we can do step #3:

0.2x100 = 20

Step #4 does not apply to us, so we can ignore that.

20% decrease is the answer.

Hope this helps and happy learning! :)

Answer:

your y is 6.7

Step-by-step explanation:

Answer:

area of square = 10 x 10 = 100 cm²

area of circle = πr² = (3.14)(5²) = 78.5 cm²

area of shaded portion = 100 - 78.5 = 21.5 cm²

Answer:

The area is [tex]21.5 cm^2[/tex](if no need to round)

The area is [tex]22 cm^2[/tex](if need to round to nearest whole number)

Step-by-step explanation:

10 x 10 = 100

5 x 5 x π = 25 π

25 x 3.14 = 78.5

100 - 78.5 = 21.5

digits of pi:3.14...
