Which of the following is a prime number between 10 and 20?
A.
14
B.
11
C.
18
D.
15

Answer:

x < - 8

Step-by-step explanation:

Given

3(x + 1) + 11 < - 2(x + 13) ← distribute parenthesis on both sides

3x + 3 + 11 < - 2x - 26

3x + 14 < - 2x - 26 ( add 2x to both sides )

5x + 14 < - 26 ( subtract 14 from both sides )

5x < - 40 ( divide both sides by 5 )

x < - 8

Answer:

x<-8

Step-by-step explanation:

3x+14<-2x-26(combine and distribute)

3x+14-14<-2x-26-14(subtract 14 from both sides)

3x<-2x-40(add 2x to both sides)

5x<-40(divide both sides by 5

x<-8(this is your final answer)

Something that the five major world religions (Christianity, Judaism, Buddhism, Hinduism and Islam) have in common is a sense of community. A sense of community provides group cohesion and identity, as well as a way for rituals and traditions to be passed down from generation to generation.

Answer:

She would get back 10.05

Step-by-step explanation:

Do 9.99 times three and you get 29.97 then do 14.99 times two and you get 29.98 then add them together to get 59.95. Next subtract 70.00 from 59.95 then you get how much change she needs back

Answer:

12.2

Step-by-step explanation:

Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)

C + 90° = 180°

C = 180° - 90°

C = 90°

Let c be the last side

Using the sine rule a/sinA = b/sinB = c/sinC

Using any of the other two sides,

10/sin55° = c/sin90°

c = 10/sin55° × sin90°

c = 10/0.8192 × 1

c = 12.21

c ≅ 12.2

Answer:

2/5

Step-by-step explanation:

you go up 2 to the right 5

Answer:

2/5 or .20

Step-by-step explanation:

m=rise/run

m=20/50 which simplifies to 2/5 because you divide 10 on the top and bottom

m=2/5

Answer:

c = √18

Step-by-step explanation:

c² = 3² + 3² = 18

Answer:

Consider all the info you are given:

The monthly allowance is 2 GB...this is basically how much data is included in the the plan so that the monthly pymt is the same every month. When the GBs used goes pass 2GB...there is a cost to that.

You're given C(x) = 30x + 50, the monthly cost of the plan

'x' is the GB of data used OVER the allowance (2GB.)

They put over in italics to give you a hint to the solution.

(a) C(0.7) is the cost when the data used goes over 2GB by 0.7 GB. C(0.7) = 30(0.7) + 5 = 26

The college student would pay $26 when they use an extra 0.7GBs (pass the allowance.)

(b) This part to the problem wants you to figure out how much the overage, pass the 2GBs, the college student can go and only end up paying $50 (the set budget)

So you the solve for x by setting C(x) = 50

30x + 5 = 50

30x = 50 - 5 = 45

x = 45/30

x = 1.5

Remember x is the overage (the GBs over the allowances), so to stay at budget, the college student can use 3.5 GBs of data (2GBs + 1.5 GBs) only pay $50 that month.

Hope this helps...

Answer:

1) 13 ft

Step-by-step explanation:

1) 13+8=21 which is greater than 15. Would be a triangle.

2) 7+8=15   This would be a single line, not a triangle.

3) 3+8<15   This would be a single line, not a triangle.

2) 15+8=23   This would be a single line, not a triangle.

Answer:

-17/-1 and 17 are the same so you are correct!

Step-by-step explanation:

in the fraction, -17/-1, you want to get rid of the negatives. in order to do that, you have to get rid of them on both the numerator and denominator! so the new fraction would be 17/1, and that would be simplified to just 17! so you are correct, i hope this helps!

Answer:

yes your cauculators correct, it is 17

Step-by-step explanation:

you need to divide the fraction since there are 2 negative numbers

Answer:

21°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°

Answer:

3gallons per minute

Step-by-step explanation:

Answer:

40 km/hr

Step-by-step explanation:

Given that:

Total distance covered in 3 hours = 60km

Speed during first 40 km = 16km/hr

Hence, time spent during the first 40 km ;

Recall:

Time = distance / speed

Time = 40 / 16

Time = 2.5 hours

Hence, speed required to cover the remaining (60 - 40) = 20km in (3 - 2.5) hours =0.5 hours

Speed = distance / time

Speed = 20 / 0. 5

Speed = 40 km / hr

Answer:

C is the correct answer

Step-by-step explanation:

Follow the steps there and  yeah

Answer:

P = 0.5c - 75

Step-by-step explanation:

Profit is = selling price. - cost price

Cost price is the amount the supplies were bought = $75

The cost of c cups at $0.5 per cup will be

0.5 * c = $0.5c

The profit here is thus;

P = 0.5c - 75

Answer:

n= -3.5

Step-by-step explanation:

n/7 - 12 = 5n +5

+12            +12

n/7 = 5n+17

*7      *7

n = (5n+17)*7

n = 35n + 119

-35n    -35n

-34n = 119

/-34     /-34

n = -3.5
