Step-by-step explanation:

-2n+1+6n+3 = -4 -7n+11

4+4n = 7- 7n

4-7 = -7n- 4n

-3/-11 = -11n/-11

n= 3/11

Answer:

n = -12/11

Step-by-step explanation:

4n = -7n - 12

4n + 7n = -7n - 12+7n

Suppose that you have the following function. void mystery(int& one, int two) { int temp temp = one; one = two; two = temp;

vlada-n [284]

Answer:

x = 15 and y = 10

Step-by-step explanation:

It is assumed that 'x' and 'y' are declared as '10' and '15' respectively. Then following the mystery(x, y) function which is pass 10 and 15 as parameter. Then we can follow the logic of the mystery function.

First, temp is assigned to one; that is temp = 10

Secondly, one is assigned to two; that is one = 15

Thirdly, two is assigned to temp; that is two = 10.

Since x and y is same as one and two; we say:

x = one = 15 and

y = two = 10.

A city water tank holds 20 gallons of water. A technician empties 25% of the tank. How many more gallons of water must be remove

Pavel [41]

20
empties 25%
25%=1/4
1/4 of 20 is 5
20-5=15
15 left
how much more must be removes so it reaches 2/5 of 20
2/5 of 20=40/5=8
15-what=8
minus 15 both sides
-what=-7
multipy-1
what=7

answer is 7 more gallons must be removed
