When Jeff played his new computer game for the first time, he scored 10,000 points. Each time he played, he increased his score by 15,000 points. How many games did Jeff have to play to reach a score of 100,000?
Answer: 6 times.
Step-by-step explanation: 10,000+15000=25000. Keep adding the answer by 15,000 until you reach 100,000. Count how many times you added 15,000.
What is the slope of a line that is perpendicular to the line y=8x+5
Answer:
-1/8
Step-by-step explanation:
Perpendicular slopes are negative reciprocals
The slope of y=8x+5 is 8, because it is in slope intercept form: y=mx+b form, where m is the slope.
Negative:
8/1--> -8/1
Reciprocal:
Flip the numerator and denominator
-8/1--> -1/8
So, the perpendicular slope of 8 is -1/8
Answer:
-8

Answer:
y=7
Step-by-step explanation:
x+y=12
x=5
12-5=7
Substitute x with 5: 5 + y = 12
Subtract 5 to both sides: 5 - 5 + y = 12 - 5
Simplify: y = 7

Step-by-step explanation:
There are 2 ways to do this, the first is to just count the number of shaded squares (35)
The second is to find the area of the larger shaded square and subtract the smaller un-shaded rectangles
The large square is 7x7=49 squares
There are two 2x3 rectangles, which are 6 each
49-6-6=37

Simplify:
2x - 10 - 3x^2 + 10x + 2x^3+ 3x^2
Group like terms:
2x^3 -3x^2 + 3x^2 + 2x -10x-10
Add similar elements -3x^2 + 3x^2:
2x^3+2x-10x-10
Add similar elements 2x-10x=-8x:
2x^3-8x-10
Your Answer Is (A) 2x^3-8x-10
plz mark me as brainliest :)
Answer:
A
Step-by-step explanation:
Let's first expand these parentheses. Remember that when we have a negative sign in front of a parentheses, that means we're multiplying each term within the parentheses by -1:
2x - 10 -3x^2 - 10x + 2x^3 + 3x^2
Now combine like terms. Like terms are the ones that have the same degree of x: 2x and -10x are like terms; -10 is by itself; -3x^2 and 3x^2 are like terms; 2x^3 is by itself. So:
2x^3 + (-3x^2 + 3x^2) + (2x - 10x) - 10
2x^3 - 8x - 10
Thus, the answer is A.

Solve for p: 5−p+6 = 8
Answer:
p=3
Step-by-step explanation:
To solve, we need to isolate the variable: p
5−p+6 = 8
Combine like terms
5+6 -p =8
11 -p=8
Subtract 11 from both sides
-p = -3
Divide both sides by -1
p=3

Find the value of x in the triangle
Answer:
x =72
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
x+77+31 = 180
Combine like terms
x + 108 = 180
Subtract 108 from each side
x+108-108 = 180-108
x =72
Answer:
72⁰
Step-by-step explanation:
By angle sum property:
x + 77 + 31 = 180
x = 180 - 108
x = 72⁰

1. The distance in kilometers to Proxima Centauri, the closest star to the Earth, is
39,900,000,000,000. Write this in scientific notation.
The equation for the distance in kilometers to Proxima Centauri is
D = 3.99 x 10¹³
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total distance from Earth to the closest star Proxima Centauri be = D
Now , the value of distance D = 39,900,000,000,000
Now , the equation to find the scientific notation is done by calculating the number of zeros in the equation
So , The distance D has 11 zeros in it
So , the distance D can be written as powers of 10 in the form
Distance D = 399 x 10¹¹
Now , 399 can be written as 3.99 x 10²
So , the equation can be simplified as
Distance D = 3.99 x 10² x 10¹¹
Distance D = 3.99 x 10¹¹⁺²
Distance D = 3.99 x 10¹³
Therefore , the value of D is 3.99 x 10¹³
Hence , The distance in kilometers to Proxima Centauri is 3.99 x 10¹³

The perimeter of a square is represented by the expression 32x - 12.8. Draw a square to represent this situation and label its side lengths. Then write three equivalent expressions for the perimeter.
Answer:
Step-by-step explanation:
Given that: The perimeter of a square is: 32x - 12.8
As we all know that, the formula to find the perimeter of a square is:
Sum of the 4 side = 4* length of the side
=> the length of 1 side: The perimeter of a square / 4
In this situation, we have length of 1 side side is:
(32x - 12.8) / 4
= 32/4x - 12.8/4
= 8x - 3.2
The 1st equivalent expressions for the perimeter: 4 *(8x - 3.2)
The 2nd equivalent expressions for the perimeter: (8x - 3.2) + (8x - 3.2) + (8x - 3.2) + (8x - 3.2)
The 3rd equivalent expressions for the perimeter: 2*(8x - 3.2) + 2*(8x - 3.2)
Half of a number is 16. Write an equation and solve to find the number?
The number will be 32 such that its half will be 16.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say that number is x
Given,
Half of a number is 16
So,
x/2 = 16
By multiplying 2 both sides
x = 32
