Answer:
11
/20
Step-by-step explanation:
Step 1- We can't subtract two fractions with different denominators. So you need to get a common denominator.
So we multiply 3 by 10, and get 30.
Then we multiply 2 by 4, and get 8.
Next we give both terms new denominators -- 4 × 10 = 40.
So now our fractions look like this:
30
/40
−8/40
Step 2- Since our denominators match, we can subtract the numerators.
30 − 8 = 22
So the answer is:
22
/40
Step 3-
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? Yes we can!

/20 is the answer
Answer:
D: -2
Step-by-step explanation:
Let's time 2 on both sides.
Then the equation will be:
(3x+4)=x
3x+4=x
-x -x
2x+4=0
-4 -4
2x=-4
<u><em>x=-2</em></u>
So the answer is D:-2.

Answer:
19.42 ft.
Step-by-step explanation:
The diameter of the semicircle is 6, so 3.14 x 6 = 18.84. Since it is a semicircle, we divide that by 2 to get 9.42.
The hypotenuse of the right triangles only matter for the perimeter. 5 + 5 = 10, and 9.42 + 10 = 19.42 ft.
Part 1: Create a scenario for an arithmetic sequence. For example,
Jasmine practices the piano for ten minutes on Monday. Every day she adds her
practice time by five minutes. If she continues this pattern, in the 7th day she will practice for 10 + 5 + 5 + 5 + 5 + 5 + 5 = 10 + 6(5) = 10 + (7 - 1)(5) = 20 + 30 = 40 minutes.
Hence the function for the 7th term in the sequence is a + (7 - 1)d = a + 6d where a is the number of minutes Jasmine practiced the piano on Monday and d is the additional number of minutes added by Jasmine to his practice time evey day.
We can solve the above question as
5b-4=2b+17
5b-2b=17+4 (taking like terms together)
3b=21
b=21/3
b=7
Hence the value of b is 7
