Write an equation where a number is multiplied by a variable, and a solution is -4/5
Answer:
5x = -4
Step-by-step explanation:
5x = -4
x would have to be -4/5 because -4 divided by 5 is -4/5.
The equation will be 5x = -4 to get the solution of -4 / 5.
What is an equation?The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the number is multiplied by a variable and the solution is -4 / 5. Let the variable be x then multiply the variable by 5 which is equivalent to -4 now solve for the value of x.
The equation will be formed as below:-
5x = -4
x = -4 / 5
Therefore, the equation will be 5x = -4 to get the solution of -4 / 5.

The first common integer that comes to mind is 40, so multiple the numerator and denominator of the left fraction by 4, and the right by 5. This gives us:
36/40 and 35/40, respectively.
Thus, the left fraction is greater than the right fraction
Express x^2 +12+11 in the form (x+p)^2 +q
Answer:
Assuming you meant x² + 12x + 11, then it would be expressed as:
(x + 6)² - 25
Step-by-step explanation:
The way you wrote the expression, the second term is not multiplied by x, and you wouldn't get the answer expected. It would just be x² + 33. Presumably that was in error and the 12 is in fact just a coefficient of x, so let's work from there.
x² + 12x + 11
= x² + 12x + 36 - 25
= (x + 6)² - 25

Answer:
Step-by-step explanation:
1) y = 2x ----------(I)
x + y = 6 -----------(II)
Plug in y =2x in equation (II)
x + 2x = 6 {Add like terms}
3x = 6
x = 6/3
x = 2
Plugin x = 2 in (I)
y = 2*2
y = 4
Check:
LHS = x +y
= 2 + 4
= 6 = RHS
2)5x + 10y = 3 ------------(I)
x = (-1/2) y ------------(II)
Substitute x = (-1/2)y in (I)
[tex]5*\frac{-1}{2}y + 10y = 3\\\\\frac{-5}{2}y+ \frac{10*2}{1*2}y = 3\\\\\frac{-5}{2}y+\frac{20}{2}y=3\\\\\frac{-5+20}{2}y = 3\\\\\frac{15}{2}y=3\\\\ y = 3*\frac{2}{15}\\\\ y = \frac{2}{5}[/tex]
Substitute y = (2/5) in equation (II)
[tex]x = \frac{-1}{2}*\frac{2}{5}\\\\x = \frac{-1}{5}[/tex]
Check:
Substitute x and y value in equation (I)
[tex]LHS = 5*\frac{-1}{5}+10*\frac{2}{5}\\\\ = -1 + 2*2\\\\ = -1 + 4\\ = 3 = RHS[/tex]
3) y - x = 3x + 2
y = 3x + 2 + x
y = 4x + 2 ---------------(I)
2x + 2y = 14 - y
2x + 2y +y = 14
2x + 3y = 14 ------------------(II)
Substitute y = 4x + 2 in equation (II)
2x + 3(4x +2) = 14
2x + 3*4x + 3*2 = 14
2x + 12x + 6 = 14
14x + 6 = 14
14x = 14 - 6
14x = 8
x = 8/14
x = 4/7
Substitute 'x' value in (I)
[tex]y = 4*\frac{4}{7} +2\\\\y = \frac{16}{7}+2\\\\y= \frac{16}{7}+\frac{2*7}{1*7}\\\\y=\frac{16}{7}+\frac{14}{7}\\\\y=\frac{30}{7}[/tex]
Check:
[tex]LHS = 2x + 3y\\\\ = 2*\frac{4}{7}+3*\frac{30}{7}\\\\ = \frac{8}{7}+\frac{90}{7}\\\\=\frac{8+90}{7}\\\\=\frac{98}{7}\\\\=14 = RHS[/tex]

A supermarket sells 11 different sandwiches, 9 snacks and 5 drinks.
They have an offer: "Buy a sandwich and get either a snack or a drink for free."
How many different meals can you get on the offer?
Answer: There are 154 different meals that you can get with this offer.
Step-by-step explanation:
The total number of combinations will be equal to the product of the numbers of options for each selection.
Here we know that:
"Buy a sandwich and get either a snack or a drink for free."
Then we have two selections:
Sandwich, where we have 11 different types.
Snack or a drink (we can choose only one) there are 9 options for snacks, and 5 options for drinks, then there is a total of 9 + 5 = 14 options.
The total number of different combinations is:
Combinations = 11*14 = 154
There are 154 different meals that you can get on the offer.

Is there a solution YES OR NO AND WHAT IS THE SOLUTION?
A log is 20 m long, correct to the nearest metre.
It has to be cut into fence posts which must be 90 cm long, correct
to the nearest 10 centimetres.
What is the largest number of fence posts that can possibly be cut from the log?
Answer:
222 fence posts
Step-by-step explanation:
Since the log is 20 m long, correct to the nearest metre and has to be cut into fence posts which must be 90 cm long, correct to the nearest 10 centimetres, there can be x fence posts 90 cm long.
So, we have x × 90 cm = 20 m
x × 0.9 m = 20 m
x = 20 m/0.9 m
x = 222.22
x ≅ 222 fence posts
So, the largest number of fence posts that can possibly be cut from the log is 222 fence posts.
y = 3/2x + 2
y = 2/3x + 6
These lines are...
Answer:
As the lines are neither parallel nor perpendicular.
Therefore, These lines are neither parallel nor perpendicular.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the lines
y = 3/2x + 2y = 2/3x + 6y = 3/2x + 2
Finding the slope of y = 3/2x + 2
comparing with the slope-intercept form of the line equation
The slope m₁ = 3/2
y = 2/3x + 6
Finding the slope of y = 2/3x + 6
comparing with the slope-intercept form of the line equation
The slope m₂ = 2/3
So,
m₁ = 3/2
m₂ = 2/3
We know that when two lines are parallel, they have equal slopes
But
m₁ ≠ m₂
3/2 ≠ 2/3
As the m₁ and m₂ are not equal.
Hence, the lines are not parallel.
We know that when two lines are perpendicular, the product of their slopes is -1.
Let us check the product of two slopes m₁ and m₂
m₁ × m₂ = 3/2 × 2/3
= 6/6
= 1
As
m₁ × m₂ ≠ -1
Thus, the lines are not perpendicular.
Conclusion:
As the lines are neither parallel nor perpendicular.
Therefore, These lines are neither parallel nor perpendicular.

If you earn $40 a year on a $500 investment, what is the annual rate of return?
Answer:
40/500 = 8%
Step-by-step explanation:
40/500 = 8%
So the answer is 8%/year. The question is if the $40 is reinvested, then will the following year's return be 8% of $540 is $43.20? If it were, this would be an example of compound returns is getting interest (or a return) on the previously earned interest. That's an 8% per annum simple yield. You'd be better off finding something that compounded your investment.
The annual rate to return will be 8%.
What is Simple interest?
A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
Given that;
Simple interest = $40
Principal amount = $500
Time = 1 year
Now,
Since, We know that;
⇒ Simple interest = P R T/100
Substitute all the values, we get;
⇒ $40 = $500 x R x 1 / 100
⇒ $40 × 100 = $500R
⇒ $400/$500 = R
⇒ R = 8%
Thus, The annual rate to return will be 8%.
