An expression is shown. 4.8 x 2 + 3.2, what is the value of the expression?
Answer:
12.8
Step-by-step explanation:
follow the steps: parenthesis, exponents, multiplication/division, addition/subraction
so, since multiplication comes before addition, you are going to do 4.8 x 2 before adding 3.2
4.8 x 2=9.6
9.6+3.2=12.8

Answer:
Number of oxen = 16
Number of chickens = 6
Step-by-step explanation:
Let,
x be the number of oxen
y be the number of chickens
According to given statement;
x+y = 22 Eqn 1
4x + 2y = 76 Eqn 2
Multiplying Eqn 1 by 4
4(x+y=22)
4x+4y=88 Eqn 3
Subtracting Eqn 2 from Eqn 3
(4x+4y)-(4x+2y)=88-76
4x+4y-4x-2y = 12
2y = 12
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{12}{2}\\y=6[/tex]
Putting y = 6 in Eqn 1
x + 6 = 22
x = 22 - 6
x = 16
Hence,
Number of oxen = 16
Number of chickens = 6

Suppose Ethan has 28 comic books. If the ratio of comic books with Native superheroes to comic books without Native
superheroes is 1:3, how many comic books have Native superheroes?
a. 6 comic books
b. 7 comic books
c. 4 comic books
d. 5 comic books
Answer:
7
Step-by-step explanation:
N. comic books : Non N. Comic books=
1:3
Total number of parts= 4
If the total number of parts is 4 then logically , 4 represents 28.
So here we'll write
4 p = 28
I p = 28/4= 7
The native comic books is 1 p.
So we'll write,
1 p = 7 ×1 = 7 comic books

Which is the graph of y =[x] -2?
Answer:
In the graph of y = x2, the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point. We can graph a parabola with a different vertex.

Given f(x)=3x^2+9x+k and the remainder when f(x) is divided by x+1 is -14, then what is the value of k?
Answer:
The value of k is -8.
Step-by-step explanation:
Given;
f(x) = 3x² + 9x + k
factor of the function = x + 1
remainder of the function = -14
let x + 1 = 0
x = -1
f(-1) = 3(-1)² + 9(-1) + k = -14
3(-1)² + 9(-1) + k = -14
3 - 9 + k = -14
-6 + k = -14
k = -14 + 6
k = -8
Therefore, the value of k is -8.

Answer:
(5,-5)
Step-by-step explanation:
Eliminate y-term
[tex](2x + 5x) + ( - 3y + 3y) = 25 + 10 \\ 7x = 35 \\ x = \frac{35}{7} \\ x = 5[/tex]
We can eliminate x-term but for this system of equations, eliminating y-term is faster.
Substitute x = 5 in any given equations.
I will choose to substitute in the first equation.
[tex]2x - 3y = 25 \\ 2(5) - 3y = 25 \\ 10 - 3y = 25 \\ 10 - 25 = 3y \\ - 1 5 = 3y \\ 3y = - 15 \\ y = - 5[/tex]
Answer Check
Substitute both x-value and y-value in any given equations
[tex]2x - 3y = 25 \\ 2(5) - 3( - 5) = 25 \\ 10 + 15 = 25 \\ 25 = 25[/tex]
The equation is true. (It is better to check both the answer for both equation.)
Thus the answer is (5,-5)

when you multiply a three-digit number by a four-digit number, what is the greatest number of digits the product can have? Explain
Answer:
7 digits
Step-by-step explanation:
When we multiply a two digit number like 17 by another 2 digit
The highest number of digits we can get as answer is 4 digits
This can be seen in the case of 10 * 10
So what this mean is that at any point in time, we can sum the numbers to get the digits
3 + 4 will give 7
And that is the greatest number we can get

what is the value of the x in this equation 6x = 54
Answer:
x = 9
Step-by-step explanation:
6x = 54
Simple way of solving, all you have to do is isolate the variable "x." To do that, divide the number, 6, by both sides.
6x / 6 = 54 / 6
54 / 6 = 9
Hence,
x = 9
Hope this helps :)
Answer:
x= 9
6x= 54
[tex] \frac{6x}{6} = \frac{54}{6} [/tex]
x = 9

23. A sales manager wants to order baseball caps with her company logo for the salespeople attending a weekend training. Unique Uniforms charges $17.75 per cap, plus a design fee of $30. Logo Direct charges $15.50 per cap, plus a delivery fee of $48. For what number of caps ordered, would the cost be the same from both vendors?
Answer:
the number of caps be 8
Step-by-step explanation:
The computation of the number of caps ordered in order to equal the cost is shown below:
Let us assume the number of cap be x
Now the equations are
17.75x + $30
15.50x + $48
Now equate these two equations
17.75x + $30 = 15.50x + $48
17.75x - 15.50x = $48 - $30
2.25x = $18
x = 8
Hence, the number of caps be 8

Answer:
11x+7
Step-by-step explanation:
This is because, in order to simplify, first you need to distribute the 2 into the x+5. So, you get 2x+10. Then you get 9x-3+2x+10. The 9x and 2x combine to get 11x. The -3+10 combine to get 7. So you have 11x+7.
