Answer: x=6
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*(3+x)-7-(x+5)=0
(2 • (x + 3) - 7) - (x + 5) = 0
x - 6 = 0
Solve : x-6 = 0
Add 6 to both sides of the equation :
x = 6
Answer:
x = 6
Step-by-step explanation:
2(3+x)-7=x+5
We move all terms to the left:
2(3+x)-7-(x+5)=0
We add all the numbers together, and all the variables
2(x+3)-(x+5)-7=0
We multiply parentheses
2x-(x+5)+6-7=0
We get rid of parentheses
2x-x-5+6-7=0
We add all the numbers together, and all the variables
x-6=0
We move all terms containing x to the left, all other terms to the right
x=6

Answer:
x = -8, 8
Step-by-step explanation:
The argument of the absolute value function can be positive or negative to give the same result.
|-8| = 8 ⇒ x = -8
|8| = 8 ⇒ x = 8
The possible solutions are x = -8, 8.
What are 2 numbers that add to 40 and subtract to 10
Answer:
25 and 15
Step-by-step explanation:
let the 2 numbers be x and y , x > y , then
x + y = 40 → (1)
x - y = 10 → (2)
add the 2 equations term by term to eliminate y
2x + 0 = 50
2x = 50 ( divide both sides by 2 )
x = 25
substitute x = 25 into (1)
25 + y = 40 ( subtract 25 from both sides )
y = 15
the 2 numbers are 25 and 15

Find the slope of JK←→ and LM←→−. Then determine whether the two lines are parallel, perpendicular, or neither.
J(1, 9), K(7, 4), L(8, 13), M(-2, 1)
m(JK) =
m(LM) =
Parallel, Perpendicular, or Neither:
perpendicular"
Step-by-step explanation:
We need to find slope (m) of both line JK and LM
Slope has formula:
Lets find slope of JK:
Lets find slope of LM:
we know if we multiply two lines' slope and get -1, they are perpendicular. Let's check:
Hence, they are perpendicular

Step-by-step explanation:
3 times x plus 4 is greater than or equal to 4 times the sum of x and 1. (Hint: 4 times the sum means you should write a distributive property problem)
Given:
3 times x plus 4 is greater than or equal to 4 times the sum of x and 1.
To find:
The inequality for the given statement and solution of the inequality.
Solution:
4 times the sum means a distributive property problem.
Now,
3 times x : 3x
3 times x plus 4 : 3x+4
Greater than or equal to : ≥
4 times the sum of x and 1 : 4(x+1)
So, the inequality is
[tex]3x+4\geq 4(x+1)[/tex]
Using distributive property, we get
[tex]3x+4\geq 4x+4[/tex]
Isolate variable terms.
[tex]4-4\geq 4x+3x[/tex]
[tex]0\geq x[/tex]
It can be written as
[tex]x\leq 0[/tex]
Therefore, the required inequality is [tex]3x+4\geq 4(x+1)[/tex] and the solution is [tex]x\leq 0[/tex].

At the beginning of the year, John had $40 in savings and saved an additional $13 each week thereafter. Isaac started the year with $80 and saved $9 every week. Let 'J' represent the amount of money John has saved tt weeks after the beginning of the year and let 'I' represent the amount of money Isaac has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t, and determine the number of weeks after the beginning of the year until John and Isaac have the same amount of money saved.
Answer:
10 weeks
Step-by-step explanation:
Let’s replace ‘t’ with numbers going up starting from 0 on both sides of the equation. Repeat until you get to 10 and you see that both are equal at $170 has been saved after 10 weeks.
John’s equation: 40 (y intercept) + 13t (saved per week)
Issac’s: 80 (y intercept) + 9t (amount saved per week)
The y-intercept represents the amount of money already saved up.

Does the graph represent y as a function of x?
Answer:
No this is not a function
Step-by-step explanation:
If you use the vertical line test which is just a line used across the graph. If we can draw any vertical line that intersects a graph more than once then it is not a function.
hazel prepared 6/8 liter os juice and 5/8 liter of guyabano juice.how many liters of juice did she prepare in all
Answer:
Step-by-step explanation:
i believe you just have to add the fractions together since the denominator are the same :)
[tex]\frac{6}{8} + \frac{5}{8} = \frac{6 + 5}{8} = \frac{11}{8}[/tex]
So in total Hazel can produce [tex]\frac{11}{8}[/tex] Liters of juice

Answer:
She should ski on Slope B because it is steeper
Step-by-step explanation:
Slope B is steeper than Slope A, so she should ski on Slope B.
First, you must find common multiples for the denominator.
[tex]\frac{15}{24}=\frac{30}{48}[/tex] slope A
[tex]\frac{12}{16}=\frac{36}{48}[/tex] slope B
Slope B has a higher vertical feet per 48 horizontal feet, so slope B is steeper.
