Answer: No solution
Step-by-step explanation:
Combine the like terms in the equation. 5x+2x=7x and -3x+10x=7x. The equation simplifies to 7x - 3= 7x.Cancel out the 7's on both sides. -3 = 0, therefore, there is no solution.Find the mathematical expression that describes the pattern 3, 7, 11, 15...

Eli’s family eats 1 3/8. Which drawing has 1 3/8 shaded
Please help
Answer:
It's b
Step-by-step explanation:
It is out of 8. Each circle has 8 sections. A full section would be 8/8 which is = to 1/1. This is because 8 divided by 8 is 1. In the second circle, three out of the 8 are shaded. This would make it 3/8. The / works as "out of". So 3 out of 8. Thus B. is 1 and 3/8
Answer:
The correct answer is B.
Step-by-step explanation:
As you can see one full circle is shaded in. This accounts for the whole number, 1, that we need. In the second image you can see a circle with 8 triangles, three of which are shaded in. This as fraction would look like 3/8.
Add up 1 + 3/8 and you get 1 and 3/8.
Thus, your answer is B.

Answer:
544 units²
Step-by-step explanation:
The surface area is the sum of the areas of the three rectangular faces and the two triangular bases.
SA = 10×14 +10×14 +12×14 + 2(1/2)(12)(8)
= 14×(10+10+12) +12×8
= 448 +96
= 544 . . . . square units
_____
The area of a rectangle is the product of its dimensions:
A = LW
The area of a triangle is half the product of its base and height:
A = (1/2)bh
Here, both triangles have the same area, so we multiplied the area of one of them by 2 to get the area of both of them.

Find the sum of the reciprocals of two consecutive even integers if the larger integer is x. please answer;-;
Step-by-step explanation:
Let the larger integer be x
Hence, the smaller integer = x-2
Hence,
Reciprocal of the x= 1/x
Reciprocal of x-2= 1/ x-2
Hence. their sum=
[tex] \frac{1}{x} + \frac{1}{x - 2} \\ = \frac{x - 2 + x}{x(x - 2)} \\ = \frac{2x - 2}{ {x}^{2} - 2x} [/tex]
The sum of the reciprocals of two consecutive even integers if the larger integer is [tex]x[/tex] is [tex]\frac{2}{x}[/tex].
For two consecutive even integers, if the larger integer is [tex]x[/tex], then the smaller one is [tex]x-2[/tex].
Their reciprocals will be [tex]\frac{1}{x}[/tex] and [tex]\frac{1}{x-2}[/tex].
Now, the sum of the reciprocals is [tex]\frac{1}{x} + \frac{1}{x-2}[/tex]
[tex]= \frac{1}{x} + \frac{1}{x-2}[/tex]
[tex]= \frac{x-2+x}{x(x-2)}[/tex]
[tex]= \frac{2x-2}{x(x-2)}[/tex]
[tex]= \frac{2(x-2)}{x(x-2)}[/tex]
[tex]= \frac{2}{x}[/tex]
So, the sum of the reciprocals of two consecutive even integers if the larger integer is [tex]x[/tex] is [tex]\frac{2}{x}[/tex].

how do you Simplify -38=7+9x
Answer : -5
Step by Step Explanation:
You first combine like terms which is -38 and 7, so subtract the 7 from the right and add it to -38.
That will give you 45. Then divide 9x and -45 by 9. That will give you -5

Find two numbers that add up to 158. The greater number is 40 more than the lesser number
The two numbers that add up to 158 are 99 and 59.
Linear EquationThe equation of variables that have a maximum power of 1 is known as a linear equation.
How to form a linear equation based on given conditions?Let the lesser number be x.
So, the greater number will be x+40.
And the sum of both the numbers is 158.
So, the resulting linear equation based on given conditions is,
x + x + 40 = 158
2x = 158 - 40
2x = 118
x = 118/2
x = 59
So, the lesser number is 59.
And the greater number is 59 + 40 = 99.
Hence, the two numbers that add up to 158 are 99 and 59.

x^2-2x-35=0 in quadratic equation
Answer:
x = -5, 7
Step-by-step explanation:
Step 1: Write equation
x² - 2x - 35 = 0
Step 2: Solve for x
Factor: (x - 7)(x + 5) = 0
Find roots: x = -5, 7
Step 3: Check
Plug in x to verify if it's a solution.
(-5)² - 2(-5) - 35 = 0
25 + 10 - 35 = 0
35 - 35 = 0
0 = 0
7² - 2(7) - 35 = 0
49 - 14 - 35 = 0
35 - 35 = 0
0 = 0
uppose you select a random card from a standard deck of
52
cards and no jokers. If you draw a face card (king, queen, or jack), you win
$5
. If you draw an ace, you win
$20
. If you draw any other card, you lose
$2
. What is the expected profit from any one draw?
Answer:
The value is [tex] E(k) = \frac{68}{52}[/tex]
Step-by-step explanation:
From the question we are told that
The total number of cards is [tex]n = 52[/tex]
Let k represent the winnings and loss when any card is drawn
So k = $5 when a faced card is drawn
So k= $ 20 when an Ace card is drawn
So g = - $2 when any other card is drawn
Generally in a standard deck of card
The number of Ace is 4
The number of queen is 4
The number of jack is 4
Therefore the number off faced cards is
R = 4 + 4 + 4 = 12
Generally the number of other cards is
Y = n - R
=> Y = 52 - 12
=> Y = 36
Generally the probability of drawing a faced card is mathematically represented as
[tex]P(k = 5) = \frac{ 12}{52}[/tex]
Generally the probability of drawing a Ace card is mathematically represented as
[tex]P(k = 20) = \frac{ 20}{52}[/tex]
Generally the probability of drawing a other card is mathematically represented as
[tex]P(k = -2) = \frac{ 36}{52}[/tex]
Generally the expected profit from any one draw is mathematically represented as
[tex]E(k) = \sum k_i * P(K = k)[/tex]
=> [tex]E(k) = 5 * \frac{ 12}{52} + 20\frac{ 20}{52} + [- 2 * \frac{ 36}{52}][/tex]
=> [tex] E(k) = \frac{68}{52}[/tex]

For the set A=

a) list the elements of A
b) find n(A)
c) Is A finite or infinite?
HELP
Answer:
a) A = {-3, -2, -1}
b) n(A) = 3
c) A is finite
Step-by-step explanation:
a) The elements of A are the integers between -4 and 0, not including those values. Those integers are -3, -2, -1, so those are the elements of set A.
A = {-3, -2, -1}
__
b) n(A) is the number of elements in set A. Obviously, there are 3:
n(A) = 3
__
c) Since n(A) is not "infinity", the set A is finite.

Answer:
n = -4
Step-by-step explanation:
Add 10 to each side, so it now looks like this: 12n = -48Divide each side by 12 to cancel out the 12 next to n. It should now look like this: n = -4I hope this helps!
