Hey there!
ANSWER: [tex]27x-1[/tex]EXPLANATION:[tex]3x+6*4x-1[/tex]
Let's add parenthesis to 6 and 4 and remove the multiplication sign.
[tex]3x+(6)(4)x-1[/tex]
This equals:
[tex]3x+24x+-1[/tex]
Now we have to combine the like terms.

Answer:
16.6
Step-by-step explanation:
By the property of intersecting secants outside of a circle, we have:
[tex]5 \times (5 + x) = 6 \times (6 + 12) \\ 25 + 5x = 6 \times 18 \\ 25 + 5x = 108 \\ 5x = 108 - 25 \\ 5x = 83 \\ x = \frac{83}{5} \\ x = 16.6[/tex]
Using compatible numbers, which is the best estimate of (28.5)(7.1)
Answer:
203
Step-by-step explanation:
estimate 28.5 = 29
estimate 7.1 = 7
there for 29 x 7 = 203
I had the same question!!!The required estimated value of the given expression is 202.
What is an estimate of the numbers?The estimate is defined as a rough view calculation that helps to predict where the product value lies.
Here,
Given expression,
= (28.5)(7.1)
Multiplying the number under the parenthesis,
Gives,
= 202.35
Now, rounding the numbers, Since the number after the decimal place is close to zero,
= 202.
Thus, the required estimated value of the given expression is 202.

Apply the distributive property to create an equivalent expression 1/5(15+10k)
Answer:
3 + 2k
Step-by-step explanation:
1/5(15+10k)
distribute
1/5 * 15 + 1/5 * 10k
3 + 2k
Answer:
3 + 2k
Step-by-step explanation:
First, I am going to explain what the distributive property is. Lets say he had the expression a(b + c). We can "distribute" the a to the b and c:
a(b + c) = ab + ac
We can apply the distributive property to the expression 1/5(15 + 10k):
1/5(15 + 10k)
= (1/5)(15) + (1/5)(10k)
= 3 + 2k
By using the distributive property, we found the expression 3 + 2k.
I hope you find my answer helpful.

11.) Sam has a total of 45 dimes and nickels. The number of dimes she has is 3 more than twice the number of nickels. How many of each coins does she have? How much money does she have altogether?
Answer:
Number of nickels: 14
Number of dimes: 31
Total money: $3.80
Step-by-step explanation:
Let number of nickels be x
Number of dimes is 2x+3
Total coins = 45
So add the number of nickels and dimes and it equals 45
x+2x+3=45
3x=45-3=42
x=42/3=14 nickels
Substitute the value of x=14 in 2x+3 to find number of dimes
2(14)+3=28+3=31 dimes
Total money is 14 nickels + 31 dimes
Nickels = 0.05 and dimes is 0.10
14(0.05)+31(0.10)=0.7+3.1=3.8

5=5ax+1 please help, its due in an hour.
solve for x
Answer:
x= 4/5a
Step-by-step explanation:
5=5/ax+1
Step 1: Multiply both sides by a.
5a=a+5x
Step 2: Flip the equation.
a+5x=5a
Step 3: Add -a to both sides.
a+5x+−a=5a+−a
5x=4a
Step 4: Divide both sides by 5.
5x/5=4a/5
x= 4/5a

F(x) = 3x3+ 8x-2
k(x) = 4x
What is the value of K(F(x))?
Answer:
[tex]k (3x^3 + 8x - 2) = 12x^3 + 32x - 8[/tex]
Step-by-step explanation:
Set up the composite result function.
k (F (x))
Evaluate k (F (x)) by substituting in the value of into.
[tex]k (3x^3 + 8x - 2) = 4 (3x^3 + 8x - 2)[/tex]
Apply the distributive property
[tex]k (3x^3 + 8x - 2) = 4 (3x^3) + 4 (8x) + 4(-2)[/tex]
Simplify
Multiply 3 by 4.
[tex]k (3x^3 + 8x - 2) = 12x^3 + 4 (8x) + 4(-2)[/tex]
Multiply 8 by 4.
[tex]k (3x^3 + 8x - 2) = 12x^3 + 32x + 4(-2)[/tex]
Multiply 4 by -2.
[tex]k (3x^3 + 8x - 2) = 12x^3 + 32x - 8[/tex]
PLEASE HELP I WILL MARK YOU BRAINLIEST THERE IS A PICTURE AT THE BOTTOM.
Answer:
72 sq. inches
Step-by-step explanation:
We are trying to find the area of the shaded part, and so we start with finding the area of the entire half that is marked (the area with measurements). The length is 8 in, as seen on the bottom, and the height is 12 in, as seen on the side. 8 * 12 = 96, so the entire portion from the shaded part to the very right is 96 sq. inches. Now we have to take out the white triangle part to find the area of the shaded part. Area of a triangle = 1/2*base * height, so we multiply 1/2 * 12 * 4, which gets us 24. Now that we know the area of the triangle, we subtract it from the previous area we got, which was the area of the shaded part plus the triangle (96). 96 - 24 = 72, so the area of the shaded portion is 72 sq. inches. Hope this helps!

The multiplication of (2.4)(–1.8) and (0.6)(–0.4) gives negative values option third is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
As we know, by the arithmetic operation rule
Multiplication of two negative values is positive.
Multiplication of one negative and one positive value is negative.
Multiplication of two positive values is positive.
In option third:
(2.4)(-1.8) = -4.32
(0.6)(-0.4) = -0.24
Thus, the multiplication of (2.4)(–1.8) and (0.6)(–0.4) gives negative values option third is correct.

Which statement could be used to explain why the function h(x) = x3 has an inverse relation that is also a function?
The graph of h(x) passes the vertical line test.
The graph of the inverse of h(x) is a vertical line.
The graph of the inverse of h(x) passes the horizontal line test.
The graph of h(x) passes the horizontal line test.
Answer:
The correct option is;
The graph of h(x) passes the horizontal line test
Step-by-step explanation:
In order to determine if a function has an inverse, and also if the inverse of the function is also a function, the function can be tested by drawing an horizontal line the graph of the function and viewing to find the following conditions;
A graph of a function that is intersected at only one point in all places (vertically) by an horizontal line indicates that the function has an inverse that is also a function, while a graph of a function that is intersected at more than one point in some places (vertically) by an horizontal line indicates that the function does not have an inverse that is also a function.
