Answer:

7 females, 24 males

Step-by-step explanation:

I solved it by using this equation:

2x + 17 = 31

then, i subtracted 17 on both sides:

2x=14

then divide by 2 on both sides:

x=7

then I added 7 to 17 to find the number of males:

7+17= 24

Answer:

x = 128 degrees

Step-by-step explanation:

First figure out the angle inside the triangle

1st step: add 55 and 73 together:

⇒ 55 + 73 = 128

2nd step: subtract the sum from 180:

⇒ 180 - 128 = 52

to find x, take 180 again and then subtract 52 from it:

⇒ 180 - 52 = 128

What is the domain of the function shown in the mapping?
Sergeeva-Olga [200]
Answer: Choice A
The domain is the set {-5, -3, 1, 2, 6} which can be written as {x| x=-5, -3, 1, 2, 6} if you want to make it clear that x is involved with the domain.

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

Explanation:

The domain is the set of x values, or the set of inputs, of a function or relation. All you have to do is list off the values in the "input" oval. Those values from top to bottom are: -3, 2, -5, 1, 6. Sort them out from smallest to largest and you get -5, -3, 1, 2, 6 which points us to choice A.

Another route you could go is eliminating choices B, C and D because -9 is not in the "input" oval.

What is three fourths plus four fifths minus seven tenths
lidiya [134]

Answer:

17/20

Step-by-step explanation:

3/4 + 4/5 - 7/10

1. Find the LCD (Least Common Denominator). The LCD is 20.

2. 20/4=5. 5*3=15. So, 3/4 becomes 15/20.

3. 20/5=4. 4*4=16. So, 4/5 becomes 16/20.

4. 20/10=2. 2*7=14. So, 7/10 becomes 14/20.

5. Your new equation is 15/20 + 16/20 - 14/20.

6. Solve from left to right.

7. 15/20 + 16/20= 31/20.

8. 31/20 - 14/20= 17/20.
