Which represents the solution to the above absolute value equation? 2|x+2|-1=5
Answers
Answer:
C. x=1 or x=-5
Step-by-step explanation:
1. First, we have to get the absolute value alone.
2|x+2|-1=5
2. Add 1 to both sides.
2|x+2|-1 +1 = 5 +1. The -1 and +1 will cancel each other out.
You will get 2|x+2|=6.
3. Divide 2 by both sides.
=
The division of 2 and the multiplication of 2 on the side of the absolute value will also cancel each other out.
You will get |x+2|=3.
4. Next, we will split this absolute value equation into two equations because we don't know if the variable of x that's inside of the absolute value is negative or not.
x+2=3 or x+2=-3.
5. Subtract 2 from all sides.
x+2 -2 =3 or x+2 -2 =-3
You will get x=1 or x=-5.
x=1 or x=-5 is your final answer.
Answer: C, x = 1 or x = -5

Answer:
Pint container.
Step-by-step explanation:
Since 1 gallon = 4 quarts ⇒ (1/2) gallons = 2 quarts
1 gallon = 8 pints ⇒ (1/2) gallons = 4 pints
1 gallon = 16 cups ⇒ (1/2) gallons = 8 cups
Therefore from the given relation with gallons we can describe the relation between the cups, quarts and pints.
(1/2) Gallon > quarts > pints > cups
If we need 1 cup of milk then a pint container will be the best choice at a grocery store.
a quart container might be the right answer

There are five pairs of numbers that multiply to 72:
2 * 36 = 72
3 * 24 = 72
4 * 18 = 72
6 * 12 = 72
8 * 9 = 72
To find two numbers that multiply to 72, you can factorize 72 into its prime factors and then look for pairs of factors. The prime factorization of 72 is:
Now, we can form pairs of factors:
2 * 36
3 * 24
4 * 18
6 * 12
8 * 9
Thus, the requried pairs that multiply to 72 are shown above.

Answer:
The number of friends that went out for dinner is 8
And their bill is $238
Step-by-step explanation:
Let's assume that the number of friends that went out for dinner to be x
And the bill for the dinner to be y
If each person contributed $32 and paid off the bill,they will have a balance of $18
32x - 18 = y_____equation 1
If each person contributed $35 and paid off the bill and also 15% tip,they will have a balance of $6.30
35x - 6.3 = y + (15% of y)
35x - 6.3 = y + (3y/20)
Open up the bracket
35x - 6.3 =(20y + 3y)/20
700x - 126 = 23y______equation 2
From equation 1,y = 32x - 18
Put the above in equation 2 and we have
700x - 126 = 23(32x -18)
700x - 126 = 736x - 414
collect like terms
36x = 288
x = 288/36
x = 8
Remember that equation 1 says that y = 32x - 18 and we now know that x = 8 .
Substitute and we have
(32 × 8) - 18
y = 238
The number of friends that went out for dinner is 8
And their bill is $238
