what are the solution of the equation 2|×+7|-3=5
Answer:
Solution of the equation 2|x +7|-3=5 is :
x1 = - 11 and x2 = - 3
Answer:
x = -3 and x = -11
Step-by-step explanation:
Find the "bare" absolute value function, then solve the two resulting equations.
2|x+7| -3 = 5
2|x +7| = 8 . . . . . add 3
|x +7| = 4 . . . . . . divide by 2
This resolves to two equations:
x +7 = 4
x = -3 . . . . . subtract 7
and
x +7 = -4
x = -11 . . . . . subtract 7
The two solutions are ...
x = -3 and x = -11
Compare the two numbers. Use > or < and = for the blank.

A truck can be rented from Company A for $120 a day plus $0.50 per mile. Company B charges $60 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
200 = x or x=200
i hope its right :)
Step-by-step explanation:
120 + 0.5x = 60 + 0.8x
-60 -60
60 + 0.5x = 0.8x
-0.5x -0.5x
60= 0.3x

Trey weighs 7 pounds less than his brother. Together they weigh 119 pounds. How much does Trey weigh?
Answer:

Step-by-step explanation:
Trey weigh 56 units.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values. We frequently observe constant change in
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
given:
Trey weighs 7 pounds less than his brother.
Together they weigh 119 pounds.
let the weight of Trey's brother is x
Trey weight= x-7
Now, Together they weigh 119 pounds.
x+ x- 7 = 119
2x= 119+ 7
2x= 126
x= 63
Hence, Trey weigh 56.

how to know the correct number of significant figures when doing a calculation?
This applies for division, multiplication, addition & subtraction
Answer:
When doing addition or subtraction with measured values, the answer should have the same precision as the least precise measurement (value) used in the calculation.The following rule applies for multiplication and division: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer.
Step-by-step explanation:
Plot C(-1,–7), D (6,–7), E(5,3), and F(5,-5) in a coordinate plane. Are CD and EF congruent?
O Yes
O No
(Must show work!!!)
Answer:
No, they are not congruent
Step-by-step explanation:
By CD and EF being congruent, we want to know if they are equal.
What we can simply do here is to find the distance between the points present.
That is, the distance between C and D, the distance between E and F
To get the distances between two points , we use the following equation
D = √(x2-x1)^2 + (y2-y1)^2
For CD, we have
D = √(6 -(-1)^2 + (-7 + 7)^2
D = √(7)^2 = 7 units
For EF, we have
D = √(5-5)^2 + (-5-3)^2
D = √(-8)^2
D = √(64) = 8 units
This clearly shows that they are both not congruent

(4x+2)=(5x-25)
4x-5x=-25-2
-x=-27
x-27
x = 27
4x + 2 = 5x - 25
First, you need to move the 2 to the other side of the equation to make it: 4x = 5x -25 - 2. Now evaluate what -25 - 2 is then you'll have: 4x= 5x + 27. Now move 5 to the other side of the equation: 5x-4x= 27 = x = 27
so, our answer is x = 27
3/4=m+1/4
What is m
Answer:
m = 1/2
Step-by-step explanation:
We need to solve the equation:
3/4 = m + 1/4
In order to solve for m, we must isolate the variable - in other words, we need to move all the m terms to one side and all the non-m terms to the other.
So, subtract 1/4 from both sides to isolate m:
3/4 - 1/4 = m
m = 2/4 = 1/2
Thus, m = 1/2.
