2 l2x+7l = 16
Please help me with this ASAP
Answer:
x = 1/2 and
x = -15/2
Step-by-step explanation:
First, get the absolute value alone on one side if the equation.
2 |2x + 7 | = 16
Divide both sides by 2.
| 2x + 7 | = 8
Once the absolute value sign is by itself, you will separate the equation into two separate equations.
2x+7=8 and 2x+7=-8
Solve these two equations separately and get two solutions.
2x + 7 = 8
Subtract 7.
2x = 1
Divide by 2.
x = 1/2 Here is one solution.
2x + 7 = -8
Subtract 7.
2x = -15
Divide by 2.
x = -15/2 Here is a second solution.
Answer:
x = - [tex]\frac{15}{2}[/tex] , x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
2 | 2x + 7 | = 16 ( divide both sides by 2 )
| 2x + 7 | = 8
the absolute value function always gives a positive result, but the expression inside can be positive or negative , that is
2x + 7 = 8 ( subtract 7 from both sides )
2x = 1 ( divide both sides by 2 )
x = [tex]\frac{1}{2}[/tex]
or
- (2x + 7) = 8
- 2x - 7 = 8 ( add 7 to both sides )
- 2x = 15 ( divide both sides by - 2 )
x = - [tex]\frac{15}{2}[/tex]
As a check
substitute these values into the left side and if equal to the right side then they are a solution
x = [tex]\frac{1}{2}[/tex]
2 | 2([tex]\frac{1}{2}[/tex] ) + 7 | = 2 | 1 + 7 | = 2 | 8 | = 16 = right side
x = - [tex]\frac{15}{2}[/tex]
2 | 2(- [tex]\frac{15}{2}[/tex] ) + 7 | = 2 | - 15 + 7 | = 2 | - 8 | = 2 | 8 | = 16 = right side
then x = - [tex]\frac{15}{2}[/tex] and x = [tex]\frac{1}{2}[/tex] are the solutions

The dimensions of the original photo are 6 x 6.
What is an area?A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.
The formula for a square's area, A = s², is the side length raised to the power of two. The 256 in2 section of the larger image was made available to us. Additionally, it was mentioned that the length of the expanded image is equal to the original image's length plus ten inches.
We can therefore create an equation to solve for x, which stands for the length of the original snapshot, based on the aforementioned statements.
A = s²
where s = ( x + 10 )
A = ( x+10 )² = 256
Solving for x,
x = 6 in.
The dimensions of the original photo are 6 x 6.

The distance between the beach and Alisa's house is 99 miles.
About how many miles away from the beach is Alisa's house?Here we need to use the general relation:
Distance = Speed*Time.
Here we know that Alisa's speed is 55 miles per hour, and she drives for 1.8 hours, then we can replace:
Speed = 55 mi/h
Time = 1.8 hours
Replacing that in the distance relation we will get:
D = (55 mi/h)*(1.8 h)= 99 mi
The distance between the beach and Alisa's house is 99 miles.

No, the Adoncia drawing will not fit on the drawing sheet.
Given adoncia is drawing to scale, she uses a 15-foot scale in the 1-inch monument. And in the drawing, the front of the monument is about 80 feet high and 200 feet long.
The given parameters are;
The scale of the drawing in the front of the monument is 15 ft = 1 in.
Actual size of the monument;
Height = 80 feet
Length = 200 feet.
So we have;
Required size of paper height = 80/15 = 16/3 = 5.33 in.
Required size of paper length = 200/15 = 40/3 = 13.33 in.
The size of the paper is 11 in. about the size of a standard 8.5-inch sheet of letterhead. equals 11 in.
Design length, 13.33" > Paper length > 11".

Rita, John, and Kareem sent 17, 7, and 68 messages, respectively.
Use algebraic expressions to solve this problem.
Let x, y, and z be the number of messages sent by Rita, John, and Kareem, respectively.
If Rita, John, and Kareem sent a total of 92 text messages during the weekend, then:
x + y + z = 92
If Kareem sent 4 times as many messages as Rita, then:
z = 4 * x
z = 4x
If John sent 10 fewer messages than Rita, then:
y = x - 10
Evaluating z = 4x and y = x - 10 to the first equation:
x + y + z = 92
x + (x - 10) + 4x = 92
x + x - 10 + 4x = 92
6x = 92 + 10
6x = 102
x = 17
Recall that y = x - 10:
y = 17 - 10
y = 7
And z = 4x:
z = 4(17)
z = 68

The volleyball team had to play quite a bit last week. they practiced .5 hours on monday, 1.3 hours on tuesday, 2.2 hours on wednesday and .8 hour on thursday. if they wanted to practice a total of 6 hours last week, how many hours did they end up practicing on friday?
The volleyball team ended up practicing for 1.2 hours on Friday.
The total number of hours the volleyball team practiced on Monday, Tuesday, Wednesday, and Thursday can be determined by adding the values given in the statement.
Therefore,
the total number of hours the team practiced on Monday, Tuesday, Wednesday, and Thursday=0.5 hours+1.3hours+2.2hours+0.8hours= 4.8 hours
Total number of hours the team practiced last week = 6 hours
The number of hours they practiced on Friday can be calculated by subtraction of the total number of hours of the week from the total number of hours on Monday, Tuesday, Wednesday, and Thursday.
Hence, the number of hours the team practiced on Friday = 6 - 4.8= 1.2 hours.
