Can Someone Help with This Distributive Property Math Question :
1. - ( 8x - 12 )
Answer:
-8x+12
Step-by-step explanation:
1. You need to distribute the (-1) from outside the bracket onto all the terms in the bracket, which includes (8x) and (-12). If there is a minus outside the bracket and one minus in the bracket, the operation would be a plus and vice versa. If there is a minus outside the bracket and one plus in the bracket, the operation would be a minus and vice versa.
- (8x - 12) = (-1) × (8x) + (-1) × (-12)
= -8x + (+12)
= -8x + 12
When a coin is tossed 20 times, it lands on heads 5 times. How does the experimental probability differ from the theoretical probability?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Number of tosses / trials = 20
Number of heads = 5
The experimental probability = the actual output of am event when an experiment or test is carried out :
Experimental probability = number of occuences / number of trials
That is :
P(head) = 5 / 20 = 1/4
Theoretical probability could be regarded as the expected output of an event based on the mathematical calculation :
Required outcome / Total possible outcomes
Theoretical probability P(head) in a toss = 1/2

Farell has a gift card with a 45 balance he bought some bags of chips that cost 2.50 each after his perchase his gift card balance was 32.50 write and solve the equation to find how how many bags of chips x he bought
Answer:
He bought 5 bags of chips
Step-by-step explanation:
Here, we want to calculate the number of bags of chips bought
The amount used on the balance is;
45-32.5 = 12.5
Let the number of chips bought be n
Since each chip cost 2.5 each;
The amount of chips bought will be 2.5 * n = 2.5n
This is same as 12.5
Thus;
2.5n = 12.5
n = 12.5/2.5
n = 5

Find the 9th term of the geometric sequence 9,27,81...
Answer:
59049
Step-by-step explanation:
The pattern is that it multiplies by 3 every time.
9*3=27, and 27*3=81.
81*3 = 243
243*3 = 729
729*3=2187
2187*3=6561
6561*3=19683
19683*3 = 59049
Write two like terms using whatever variable(s) you’d like. Be sure to include exponents. Explain why these are like terms.
Answer: 10x^2+7x^2= 17x^2
Step-by-step explanation:
This binomial is alike because they hold the same value of exponent which is why they can be combined, since you add the coefficient of the variables leaving the exponents unchanged.

Answer:
I think it may be y=2X+1 hope it's right
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-1}{0+1}[/tex] = - 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 ← equation of line

A seal has 1,500 nerves per whisker. That is 101010 times as many as a rat has. How many nerves per whisker does a rat have?
Answer:
0.01485...
Step-by-step explanation:
Given:
A seal has 1,500 nerves per whiskerThis is 101,010 times as much as a rat has per whiskerWe will:
Divide the number 1,500 by 101,0101,500 ÷ 101,010 = 0.0148500149
0.0148500149 ⇒ 0.01485 when rounded
Your answer: 0.0148500149, 0.01485 when rounded

What is the coefficient of x 8+5x-y
Answer:
The coefficient is 5.
Step-by-step explanation:
The coefficient is the number that comes before the variable, 8 wouldn't be a coefficient because it doesn't have a variable, so therefore the correct answer is 5.
I hope I could help :)
The solution is 5
The coefficient of the equation A = 8 + 5x - y is 5
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 ,
Let the equation be represented as A
The value of A is
A = 8 + 5x - y be equation (1)
Let the coefficient be = c
The coefficients are the numbers by which the variables in an equation are multiplied
So , the coefficients of the equation is 5
Therefore , the value of c = 5
Hence , the coefficient of the equation is 5

Answer:
3
Step-by-step explanation:
.......................
Answer:
3
Step-by-step explanation:
The formula of to calculate slope of a linear function is
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope and so lets take any two points from the table to calculate the slope. Lets take,
(0 , 4) and (1 , 7) and lets plug it in the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{7-4}{1-0}\\\\m=3[/tex]
So the slope of the function is 3
For a play, the ticket prices were $5.00 per child and $8.50 per adult. the children bought 100 more tickets than the adults. the total box office income was $905.00. how many tickets of each type were sold?
Using the concept of linear equations, number of tickets bought by the children and adults are 130 and 30 respectively.
What is Linear Equation in one variable?The linear equation in one variable is written as ax + b = 0, where a and b are two integers and x is a variable. This equation has only one solution.
Given that,
Ticket price per child = $5.00
Ticket price per adult = $8.50
Total box office income = $905.00
Let the tickets bought by the adults be x.
Then, tickets bought by the children will be x + 100.
Here, x is a variable.
Linear equation will be:
8.50x + 5(x + 100) = 905.00
8.50x + 5x + 500 = 905.00
13.50x + 500 = 905.00
13.50x = 905.00 - 500
13.50x = 405.00
x = 405.00/13.50
x = 30
So, the tickets bought by the adults = 30
And tickets bought by the children = x + 100
Tickets bought by the children = 30 + 100
Tickets bought by the children = 130
