The solution of the inequality $2x-10$ is $x$

All the numbers less than 21 are included on the number line.

Step-by-step explanation:

We need to solve the inequality $2x-10$ and represent the solution on number line

Solving the inequality:

$2x-10$

Adding 10 on both sides

$2x-10+10$

$2x$

Divide both sides by 2

$2x/2$

$x$

So, the solution of the inequality $2x-10$ is $x$

All the numbers less than 21 are included on the number line.

The number line is shown in figure attached.

Answer:

Hey there!

We can write this equation, where x is the hourly rate and y is the fixed fee.

4x+y=270

7x+y=420

4x+y=270

-7x-y=-420

-3x=-150

x=50

4(50)+y=270

200+y=270

y=70.

The fixed fee is G. $70.

Let me know if this helps :)

Let's go through each answer choice one at a time.
--------------------------------------------------
Choice A
3/4 < 5/7
3*7 < 4*5 ... cross multiply
21 < 20
The last inequality is false, so the original inequality is false
Choice A is false
--------------------------------------------------
Choice B
2/3 > 5/6
2*6 > 3*5 ... cross multiply
12 > 15
The last inequality is false, so the original inequality is false
Choice B is false
--------------------------------------------------
Choice C
5/8 > 6/10
5*10 > 8*6 ... cross multiply
50 > 48
The last inequality is true, so the original inequality is true
Choice C is true
--------------------------------------------------
Choice D
4/5 < 2/9
4*9 < 5*2 ... cross multiply
36 < 10
The last inequality is false, so the original inequality is false
Choice D is false
--------------------------------------------------
In summary, we have
A. False
B. False
C. True
D. False
So the final answer is choice C

Someone help me with this find points a b c

NISA [10]

Answer:

<a=32

<b=40

<c=40

Step-by-step explanation:

to find angle a you have to subtract the 50 minus 180 to find the angle close to the 50 because angles in a straight line add up to 180. the answer will be

180-50=130

after finding the angle in that triangle you must add it to the other angle present which is 18° then subtract by 180 because angles in a straight line add up to 180

130+18+a=180

a=180-148

a=32 and that's how you find a

to find b you must know that the angle at the center is twice the angle at the circumference meaning the large angle C is 90°,now if it's 90° inorder to find the big angle B you must add the 18+90 then subtract 180

18+90+B=180

B=180-108

=72

since the combination of angle a and b will give you 72 you can find angle c by subtracting a from 72

c=72-32

=40

then if you look at angle c and angle b you can tell that they are alternating meaning angle b is also 40

I hope this helps

mezya [45]

To solve this, you must add 2/3 + 1/4 + 1/4.
First, convert them all to have common denominators.
2/3 x 4/4= 8/12
1/4 x 3/3= 3/12
1/4 x 3/3= 3/12
Now, add them...
8/12 + 3/12 + 3/12 = 14/12 gallons.
Now, since it's an improper fraction, first lets simplify...
14/12 divided by 2/2 = 7/6
Now, convert 7/6 into a mixed number...
7/6= 1 1/6
SO, Lila collected 1 and 1/16 of a gallon in all

Need helping solving for zero domain and range!!

Contact [7]

Answer:

Zero: (1,0)

Domain: -infinity, + infinity

Range: -infinity, + infinity

Step-by-step explanation:

I know that the zero answer is right because zero is just another name for x intercept. Range is all possible y values and domain is all possible x values
