3. 4.5x + 10 (I think, not quite sure)
4. 0.25 - 5x (I think, also not quite sure)
5. -8x - 5y + 5.5
Step-by-step explanation:
2. Distribute the -2 to all terms except -1.
-2(4x + 2.5) - 1
-8x - 5 -1
-8x - 6
5. Combine 6x and -14x (6 - 14 = -8).
6x - 5y - 14x + 5.5
-8x - 5y + 5.5

A store manager combines 2 lb of trail mix that contains some cashew nuts with 30 lb
of trail mix that is 20% cashews. The result is a trail mix that is 25% cashews. What is the concentration of cashews in the first mixture?
Answers
Answer:
100%
Step-by-step explanation:
Let p = percent of cashews in first mix
2p = lb. of cashews in first mix
30(.20) = 6 = lb. of cashews in second mix
32(.25) = 8 = lb. of cashews in the combined mix
So,
lb. of cashews in first mix + lb. of cashews in second mix = lb. of cashews in the combined mix
2p + 6 = 8
2p = 2
p = 1 = 100%
Answer:
100%

One of the sides of a parallelogram has the length of 5 in. can the lengths of the diagonals be: 4 in and 6 in?
PLEASE PROVIDE AN EXPLANATION
Answers
Answer:
Yes, the diagonals could be 6 and 7 in. In a parallelogram, only the opposite sides of the parallelogram are congruent.
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other, so you can set the labeled segments equal to one another and then solve for . \displaystyle 20 - 3x = 2x - 4 \rightarrow 24 = 5x \rightarrow 4.8 = x. Then, substitute 4.8 for in each labeled segment to get a total of 11.2 for the diagonal length.

Abigail and her children went into a bakery and she bought $11.25 worth of cupcakes and cookies. Each cupcake costs $3.75 and each cookie costs $0.75. She bought a total of 7 cupcakes and cookies altogether. Graphically solve a system of equations in order to determine the number of cupcakes, X, and the number of cookies, y, that Abigail bought.
Answers
Answer:
Number of cupcakes = 2
Number of cookies = 5
Step-by-step explanation:
Let [tex]x[/tex] denotes the number of cupcakes and [tex]y[/tex] denotes the number of cookies.
Abigail bought $11.25 worth of cupcakes and cookies such that each cupcake costs $3.75 and each cookie costs $0.75.
[tex]3.75x+0.75y=11.25[/tex]
At [tex]x=0;[/tex] [tex]0.75y=11.25[/tex]
[tex]y=\frac{11.25}{0.75} =15[/tex]
At [tex]y=0;3.75x=11.25[/tex]
[tex]x=\frac{11.25}{3.75}=3[/tex]
So, plot the points [tex](0,15)\,,\,(3,0)[/tex]
Also,
Abigail bought a total of 7 cupcakes and cookies altogether.
[tex]x+y=7[/tex]
At [tex]x=0;0+y=7[/tex]
[tex]y=7[/tex]
At [tex]y=0;x+0=7[/tex]
[tex]x=7[/tex]
So, plot points [tex](7,0)\,,\,(0,7)[/tex]
From the graph, solution is [tex](2,5)[/tex]
Number of cupcakes = 2
Number of cookies = 5

d) first degree binomial
can some one plss help me??
Answers
Answer:
a) third degree trinomial
Step-by-step explanation:
The degree of a polynomial is the same as the degree of the term of the polynomial with the highest degree. The degree of a term is the sum of all the exponents of the variables of the term. Remember that a variable such as x, or y, or z has degree 1.
Now we look at the degree of each term:
2x: degree 1 (since x is the same as x^1)
10x^2: degree 2
-x^3: degree 3
The term with highest degree is the last term which has degree 3, so the degree of the polynomial is 3.
The polynomial has 3 terms, so it is a trinomial.
Answer: a) third degree trinomial

x2 + x < 20
Answers
Answer:
x<18
Step-by-step explanation:
2+x<20
Answer:
(-5, 4)
Step-by-step explanation:
x^2 + x < 20 can be rewritten as a quadratic in standard form: x^2 + x - 20 < 0. Recognize that the graph of x^2 + x - 20 is that of a parabola that opens up. Because the y-intercept (0, -20) is below the x-axis, we know for certain tht the graph intersects the x-axis in two places. Our job is to determine the two horizontal intercepts, which in turn determine the solution set.
x^2 + x - 20 = 0 factors as follows: (x + 5)(x - 4) = 0, whose roots are -5 and 4.
These two roots form 3 intervals: (-infinity, -5), (-5, 4) and (4, infinity). We now must identify on which intervals x^2 + x - 20 is less than 0 (that is, on which intervals the graph is below the x-axis). Choose three test values for x: the first could be -6 (which is in the set (-infinity, -5) ); x^2 + x - 20 is + there, and so the graph is above the x-axis and x^2 + x - 20 is positive. Reject this.
Next, test x = 0; x^2 + x - 20 is negative there, meaning that x^2 + x - 20 < 0 and that x^2 + x < 20. Thus, the solution is (-5, 4). It can be shown that x^2 + x - 20 is positive again for x-values within the interval (4, infinity).
