Answer:
C. Infinitely many solutions.
Step-by-step explanation:
-4x - 7 + 10x = -7 + 6x
Combine like terms on the left side. Rearrange the right side.
6x - 7 = 6x - 7
Add 7 to both sides.
6x = 6x
Subtract 6x from both sides.
0 = 0
0 = 0 is a true statement.
Both sides are equal, so all real values of x make the equation true.
Answer: C. Infinitely many solutions.

From the last question, 146 is the exterior angle.
That means that
5y + 3 + 4y+8 = 146
9y + 11 = 146 Subtract 11 from both sides
9y = 146 - 11 Combine the right
9y = 135 Divide by 9
y = 135/9
y = 15
Solve for x
x and 146 are supplementary.
x + 146 = 180 Subtract 146 from both sides
x = 180 - 146
x = 34
Solve For <A and <B
A
A = 5y + 3
A = 5*15 + 3
A = 75 + 3
A = 78
B
B = 4y + 8
B = 4*15 + 8
B = 68
========
The three angles are
A: 78
B: 68
X: 34
========
The side Opposite A is the longest because A is the biggest angle: BC
The side Opposite B is the second longest line: AC
The shortest line is AB
Conclusion
BC, AC, AB

Answer:
✅⅓(x - 5) = -⅔
✅distribute ⅓
✅x = 3
Step-by-step explanation:
Let the number be x.
The difference of a number and 5 ==> x - 5
⅓ times the difference of a number and 5 equals -⅔, would be expressed as:
✅⅓(x - 5) = -⅔
✔️To solve for x, one possible first step is to distribute ⅓.
Thus,
⅓x - ⁵/3 = -⅔
Add ⁵/3 to both sides
⅓x = -⅔ + ⁵/3
⅓x = (-2 + 5)/3
⅓x = ³/3
⅓x = 1
Multiply both sides by 3
x = 3
In a store parking lot, 60% of the vehicles are white. If there are 24 white vehicles, how many vehicles are in the parking lot?
Answer:
40 vehicle's
Step-by-step explanation:
set up an equation of 60/100=24/x, x is the unknow amount.
then "multiply like a butterfly" to get 2400=60x then divide both sides by x to get 40
you can also mutiply 40 by 60% to check your answer

Which equation is in slop-intercept form?
A. 2x+3y=21
B. y-7=3(x+4)
C. [tex]Y^{2}[/tex]=3[tex]x^{2}[/tex]-6
D. Y=3X+12
Step-by-step explanation:
Only D, y = 3x + 12 is in slope-intercept form.
Answer:
[tex]\boxed {\boxed {\sf y=3x+12}}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation is:
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Let's evaluate each answer choice. The one in slope-intercept form will have the y variable isolated on one side of the equation.
A. 2x+3y=21: This is not is slope-intercept form. The y is not isolated. B. y-7=3(x+4): Again, this isn't slope-intercept form. A 7 is being subtracted from y C. y²=3x²-6: This also isn't correct. y is being squared. D. y=3x+12: This choice is correct. The y is all alone on the left side of the equation.The equation in slope-intercept form is D. y=3x+12

A new auditorium is begging built for a college the balcony has 200 seats the floor has 25 rows with x seats in each row the number of people in the auditorium must be under 750 to meet safety regulations what is the solution of this inequality and what is it's meaning
Question:
A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?
Answer:
[tex]200 + 25x < 750[/tex]
Number of seats in a row must be less than 22
Step-by-step explanation:
Given
Total = Less than 750
Current Seats = 200
Rows = 25
Seat per row = x
Required
Represent as an inequality
The scenario will be represented as:
[tex]Current\ Seats + Rows * x = Total[/tex]
Substitute 200 for Current Seats
[tex]200 + Rows * x = Total[/tex]
Substitute 25 for Rows
[tex]200 + 25* x = Total[/tex]
[tex]200 + 25x = Total[/tex]
Substitute <750 for Total.
The equation then becomes
[tex]200 + 25x < 750[/tex]
Solving further:
[tex]25x < 750 - 200[/tex]
[tex]25x < 550[/tex]
[tex]x < \frac{550}{25}[/tex]
[tex]x < 22[/tex]
This means that:
Number of seats in a row must be less than 22

The length of the sides of a square is given by the expression 4.8x + 2.4. Which expression represents the perimeter of the square? A. 4.8x + 2.4 + 4 B. 19.2x + 2.4 C. 8(2.4x + 1.2) D. 4.8x + 9.6
Answer:
Option C. 8( 2.4x + 1.2 )
Step-by-step explanation:
Length of the sides of a square is given by the expression ( 4.8x + 2.4 )
Then we have to find the expression that represents the perimeter of the given square.
Since perimeter of a square = 4 × ( side of the square )
= 4( 4.8x + 2.4 )
= 8( 2.4x + 1.2 )
Therefore, option C. 8(2.4x + 1.2) represents the perimeter of the square.
Answer:
Option C. 8( 2.4x + 1.2 )
Solve the equation for x: 3(x + 2) + 8x = 11x + 7
Step-by-step explanation:
Use the Distributive Property for the left side of the equation.
[tex]a( b+ c) = ab + ac[/tex]
Use the Distributive Property:
[tex]3x + 6 + 8x = 11x + 7[/tex]
[tex]11x + 6 = 11x + 7[/tex]

The leopard population in an African wildlife area is currently 17. Due to a new conservation effort, conservationists hope the leopard population will increase by 4 animals each year for the next 20 years. Which explicit rule represents the leopard population sequence?
Answer:
[tex]a{_n} = 17 + (n - 1)4[/tex] for n = 1, 2, . . . , 20.
Step-by-step explanation:
This is an arithmetic sequence, because the population is said to increase by 4 animals yearly. The formula for the nth term in an arithmetic sequence is given by:
[tex]a{_n} = a{_1} + (n - 1)d[/tex] where [tex]a_n[/tex] is the nth term, [/tex]a_1[/tex] is the first term, n = 1, 2, . . . and d is the common difference.
Since they are currently 17, this implies that the first number in the population sequence will be 17. In order words, the first term is 17.
Since they increase by 4 yearly, then the common difference is 4.
Since it's for 20years, the n = 1, 2, . . ., 20. The explicit formula is therefore:
[tex]a{_n} = 17 + (n - 1)4[/tex] for n = 1, 2, . . . , 20.

Definition of zero pair
Answer:
a pair number whose sum is zero e.g +1-1. used to illustrate addition and subtraction problems. with positive and negative integers.
Zero pairs provide a fundamental understanding of the relationship between positive and negative numbers and their interaction in mathematical operations.
In mathematics, a zero pair refers to a pair of numbers that, when combined, result in a sum of zero. Zero pairs are significant in the context of operations involving positive and negative numbers, particularly addition and subtraction.
When a positive number is paired with an equal negative number, the sum is always zero. For example, a zero pair can be formed by combining +3 and -3, or +10 and -10.
Zero pairs are essential in understanding the concept of balancing equations or simplifying expressions involving positive and negative numbers. They help to demonstrate the cancellation or elimination of opposite values. By identifying and removing zero pairs, equations and expressions can be simplified to their simplest form.
For instance, in the expression 5 + (-5) + 8 + (-8), the pairs +5 and -5, and +8 and -8 form zero pairs. When combined, they result in a sum of zero. Simplifying the expression with zero pairs, we are left with 0 + 0 = 0.
Overall, zero pairs provide a fundamental understanding of the relationship between positive and negative numbers and their interaction in mathematical operations.
