Define the two numbers
-----------------------------------------------------------
Let the first number be x.
Let the second number be y.
------------------------------------------------------------
Form equations and solve x and y
------------------------------------------------------------
x + 2y = 14 ------------------ (1)
2x + y = 31 ------------------ (2)
------------------------------------------------------------
Equation (1) x 2
------------------------------------------------------------
2x + 4y = 28 ---------------(1a)
------------------------------------------------------------
Equation (1a) - 2
------------------------------------------------------------
3y = 28 - 31
3y = -3
y = -1
------------------------------------------------------------
Substitute y = -1 into (1)
------------------------------------------------------------
x + 2(-1) = 14
x -2 = 14
x = 14 + 2
x = 16
------------------------------------------------------------
Answer: x =16, y = -1
------------------------------------------------------------
In order to solve this problem you need to set up an equation.
12 = x + (x + 4)
x will represent the number of women, and (x+4) will represent the number of men, because there are 4 more men than women.
12 = x + x + 4
12 = 2x + 4
8 = 2x
x = 4
This is the answer to how many women there are, but your question is asking for the number of MEN, so we have to go one more step farther. Like stated before, the expression for the number of men is shown like so: (x +4). Now we just need to plug in the number for x.
(x+4)
4+4
8
There were 8 men on the jury.
Answer:
D. 58
Step-by-step explanation:
The multiplication and division are performed first.
... 32 +6·5 -7 +12/4
... = 32 +30 -7 +3
Then, the Order of Operations tells you to do the addition/subtraction left to right. Of course, if you keep the sign with the number, you can do the addition in any convenient order.
... = 62 -7 +3
... = 55 +3
... = 58
