7x+2x=68+103 help please
Answer:
19
Step-by-step explanation:
7x + 2x = 9x
9x = 68 + 103
68 + 103 = 171
9x = 171
Divide it
19
Answer:
I'm sure the correct answer is x = 19
Step-by-step explanation:
7x + 2x = 9x
68 + 103 = 171
divide both sides by 9 and the it gives you x = 19

What is an equation of the line that passes through the point (2, -5) and is parallel to the line
6x + y = 6?
The required equation of the line is 6x + y = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
First, we have to determine the slope of the line 6x + y = 6 by placing it into a slope-intercept form:
6x + y = 6 ⇒ y = -6x + 6
Therefore, the slope of the line is m = - 6
Since the required line passes through the point at (2, -5).
Let the line (y - y₁) = m(x -x₁ )
Here x₁ = 2, y₁ = -5
Substitute the values in the equation,
So, y - (-5) = -6(x - 2)
⇒ y + 5 = -6x + 12
⇒ 6x + y = 7
Hence, the required equation of the line is 6x + y = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).

Solve for x: 4 − (x + 2) −7
x < −9
Answer:
35 im mot sure
Step-by-step explanation:
Answer: x > 11/8
Step-by-step explanation: Here is why
4 − (x+2) − 7x < −9 (simplify)
-8x + 2 - 2 < -9 -2 ( subtract)
-8x < -11
-8x/-8 < -11/-8 (divide)
= x > 11/8

The top of a ladder is placed against the side of a house. The ladder is 15 feet long and the wall is 12 feet high. How far from the wall will the base of the ladder by positioned if the top ladder meets the top of the wall?
Answer:
9 ft
Step-by-step explanation:
The ladder is 15 feet long
The wall is 12 feet high
Therefore the distance between the base of the wall and the ladder can be calculated by applying phythagoreans theory
c^2= a^2 + b^2
15^2 = a^2 + 12^2
225= a^2 + 144
225-144= a^2
a^2= 81
a= 9 ft
Answer: A

What is the value of x?
Enter your answer in the box.
Answer:
X = 40
Step-by-step explanation:
{ 2 (x + 10)} = (3x - 30)
2x + 10 = 3x - 30
10 = 3x - 2x - 30
10 + 30 = 1x
40 = 1x
X = 40
Chloe and Charlie are taking a trip to the pet store to buy some things for their new puppy. They know that they need a bag of food that costs $7, and they also want to buy some new toys for the puppy. They find a bargain barrel containing toys that cost $2 each. Write an expression for the amount of money they will spend if the number of toys they buy is t.
Answer:
7 + t = 13$
If this is wrong I'm so sorry but that's what I think it is.
The required total cost for Chole and Charlie is y = 7 + 2t.
Given that,
Chloe and Charlie are taking a trip to the pet store to buy some things for their new puppy. They know that they need a bag of food that costs $7, and they also want to buy some new toys for the puppy. They find a bargain barrel containing toys that cost $2 each.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the total cost be y,
According to the given condition,
Total cost = 7 + 2t
where 2t is the total cost of the toys purchased.
y = 7 + 2t
Thus, the required total cost for Chole and Charlie is y = 7 + 2t.

Here,
Distance = (18 mpg)(8 gallons) = 144 miles
28. The difference between two
numbers is 80. If the ratio of two
numbers is 3:5, find the
numbers *
Answer:
We set up 2 equations:
n - m = 80 so "n" is the larger number
A) n - m = 80
B) m / n = .6
A) n = 80 + m
B) m = .6 n so B) n = (5/3) m
We substitute B) into A)
(5/3) m = 80 + m
(2/3) m = 80
m = 1.5 * 80
m = 120
n = 200
