Answer:
x = 0.75
Step-by-step explanation:
Simplifying
(7x + -5) + -1(3x + -2) = 0
Reorder the terms:
(-5 + 7x) + -1(3x + -2) = 0
Remove parenthesis around (-5 + 7x)
-5 + 7x + -1(3x + -2) = 0
Reorder the terms:
-5 + 7x + -1(-2 + 3x) = 0
-5 + 7x + (-2 * -1 + 3x * -1) = 0
-5 + 7x + (2 + -3x) = 0
Reorder the terms:
-5 + 2 + 7x + -3x = 0
Combine like terms: -5 + 2 = -3
-3 + 7x + -3x = 0
Combine like terms: 7x + -3x = 4x
-3 + 4x = 0
Solving
-3 + 4x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 4x = 0 + 3
Combine like terms: -3 + 3 = 0
0 + 4x = 0 + 3
4x = 0 + 3
Combine like terms: 0 + 3 = 3
4x = 3
Divide each side by '4'.
x = 0.75
Simplifying
x = 0.75
Answer:
When solving equations like this, you have to use a method called PEMDAS.
This stands for:
P- ParentesisE- ExponentsM- MultiplyD- DivideA- AdditionS- Subtraction(7x + 5) - (3x +2)
Let's work it out...
Step one) Distribute the equation
Distributing the equation helps simplify it and make solving much easier.
(7x−5) − 1(3x−2)
(7x−5) − 3x + 2
Step two) Eliminate the Parenthesis
Now that the equation is simplified, you can take out the Parenthesis.
(7x − 5) − 3x + 2
7x − 5 − 3x + 2
Step three: Add the numbers
Add the two whole numbers together (-5 + 2)
7x − 5 − 3x + 2
7x − 3 − 3x
Step four: Combine like terms
Combine like terms or the numbers with variables (7x - 3x)
7x − 3 − 3x
4x − 3
Solution
4x - 3Hope this helped! :)

The value of x is: x = 35.57.
Here, we have,
given that,
from the given diagram, we get,
it is a right angle triangle,
base = x
hypotenuse = 37
and angle = 16°
now, we know that,
cos θ = adjacent / hypotenuse
so, we get,
cos 16° = x/37
The value of cos 16° is equal to the x-coordinate (0.9613).
∴ cos 16° = 0.9613.
=> 0.9613 = x/37
=> x = 35.57
Hence, The value of x is: x = 35.57.

On a map, Norristown is 18 miles south of Lincoln, and Lincoln is 29 miles west of Allenport. Find the distance from Norristown to Allenport
Answer:34.1
Step-by-step explanation:
The lines represented by the equations y=\frac{4}{5}x+8y= 5 4 x+8 and 20y+25x=18020y+25x=180 are
Given:
The equations of lines are
[tex]y=\dfrac{4}{5}x+8[/tex]
[tex]20y+25x=180[/tex]
To find:
The relation between two of lines.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
We have,
[tex]y=\dfrac{4}{5}x+8[/tex] ...(i)
[tex]20y+25x=180[/tex] ...(ii)
Equation (i) can be written as
[tex]20y=-25x+180[/tex]
[tex]y=\dfrac{-25x+180}{20}[/tex]
[tex]y=\dfrac{-25x}{20}+\dfrac{180}{20}[/tex]
[tex]y=\dfrac{-5x}{4}+9[/tex] ...(iii)
On comparing (i) with slope intercept form, we get
[tex]m_1=\dfrac{4}{5}[/tex]
On comparing (iii) with slope intercept form, we get
[tex]m_2=-\dfrac{5}{4}[/tex]
Now,
[tex]m_1\times m_2=\dfrac{4}{5}\times (-\dfrac{5}{4})[/tex]
[tex]m_1\times m_2=-1[/tex]
The product of slopes of both lines is -1. We know that the product of slopes of two perpendicular lines is -1.
Therefore, the given lines are perpendicular.
Question 2 (1 point) (11.01 MC) Nina has a piece of fabric measuring 5 yards. How many 1-inch strips can be cut from the fabric? (1 point) a 17 strips b 50 strips c 60 strips d 120 strips
Answer:
180 strips
Step-by-step explanation:
Note that:
1 yard = 36 inches
5 yards = x
Cross Multiply
x = 5 × 36 inches
x = 180 inches
Hence:
1 piece of fabric = 180 inches
How many 1-inch strips can be cut from the fabric?
180 inches = 1 piece of fabric
1 inch = x
x = 180 strips
what can be concluded from the graph

Answer:
x = 5
Step-by-step explanation:
The sum of the angles of a triangle is 180°.
(180 - 18x + 5) + (-1 + 8x) + 46 = 180
⇒ 180 - 18x + 5 - 1 + 8x + 46 = 180
⇒ -10x + 230 = 180
⇒ -10x = -50
⇒ x = 5

2. The length of a rectangle is 5 feet more than the width. The perimeter of the rectangle is
58 feet.
Find the width of the rectangle.
The width of the rectangle is 12ft.
What is the difference between area and perimeter of a rectangle?The rectangle's perimeter is calculated using its length. Given by the total of the rectangle's sides, it is stated in linear units.
The space inside the rectangle is measured by area, on the other hand. It is measured in square units and equals the sum of the rectangle's length and width.
Let us suppose the width of the given rectangle be x
According to the given question;
Length of rectangle is 5ft more than its width
Therefore, length of rectangle= x+5
We know that,
Perimeter of rectangle = 2 ( length+breadth)
Perimeter of rectangle = 2[x+(x+5)]
It is given in the question that perimeter of the rectangle is 58ft
Thus,
⇒2( length+breadth) =58
⇒ 2[x+(x+5)] = 58
⇒ 2 (2x+5) = 58
⇒ 4x + 10 = 58
⇒ 4x = 58- 10 = 48
⇒ 4x = 48
⇒ x = 12
Thus, width of rectangle = 12 ft
length of rectangle = x+5 = 12+5 = 17ft
Hence, the width of the rectangle is 12ft.

2.85 kilograms of sugar is mixed with 3.15 kilograms of flour what percent of this mixture is flour?
Answer: 52.5%
Step-by-step explanation:
First add up both quantities to find out the total quantity of the mixture.
= 2.85 + 3.15
= 6 kg
The flour is 3.15 kg out of this total so the percentage is:
= 3.15 / 6 * 100%
= 52.5%
Find all numbers whose absolute value is 6.

Given :
Measure of an angle = 15°
Measure of the second angle = 45°
Let the measure of the third angle be x.
We know that :
▪︎Sum of all angles of a triangle = 180°[angle sum property]
Which means :
[tex] =\tt 15 + 45 + x = 180[/tex]
[tex] =\tt 60 + x = 180[/tex]
[tex] =\tt x = 180 - 60[/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 120°[/tex]
Thus, the measure of the third angle = 120°
Since the sum of all these angles is equivalent to 180°[15+45+120=180] we can conclude that we have found out the correct measure of the third angle.
Therefore, the correct option is (C) 120
