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.

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]

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
A soup recipe calls for 6 chopped onions. You want to make 1/4 of the recipe. How many onions will you need? Which proportion will give the correct answer?
Answer:
Step-by-step explanation:
One way to "solve" this problem is to write and solve an equation of proportions:
(1/4) recipe x
----------------- = ------------------
1 recipe 6 onions
Cross-multiplying, we get x(1 recipe) = (1/4 recipe)(6 onions), which simplifies to
x = 6/4 onions, or x = 1.5 onions
See the proportion above.
We need 1.5 onions to make 1/4th of the recipe and this is in direct proportion.
What is direct and inverse proportion ?In direct proportion if one quantity increases the other quantity also increases and vice versa and in indirect proportion if one quantity increases the other quantity decreases and vice versa.
According to the given question a soup recipe calls for 6 chopped onions.
We want to make 1/4th of the soup so the no. of onions required will be
1 : 6 : : 1/4 : x.
1/6 = (1/4)/x.
1/6 = 1/4x
4x = 6
x = 6/4
x = 1.5.
So to make 1/4th of the total recipe we need 1.5 onions,This relation is in direct proportion since as both the quantities will increase and decrease at the same time.

Your basketball team wins a game by 13 points. The opposing team scores 72 points. Explain how to find your team’s score.
Answer:
85
Step-by-step explanation:
You can set this up as an algebraic equation by assigning variables to each part of the question. So you could say Y - 13 = 72 If you are in middle school they will expect all that.
If you want the easy way you could say, 72 + 13= 85 because we beat you by 13 and you only scored 72 points. So I add 13 to their lame score and we get my great score.

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].

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.
