Answer:
x = 3
Step-by-step explanation:
-5x + 10 = -5
-10 -10
-5x = -15
divide by -5
x = 3
Answer:
[tex]x = 11[/tex]
Step-by-step explanation:
[tex] - 5(x - 10) = - 5[/tex]
[tex] - 5 \times x - 10 \times - 5 = - 5[/tex]
[tex] - 5x + 50 = - 5[/tex]
[tex] - 5x = - 5 - 50[/tex]
[tex] - 5x = - 55[/tex]
[tex] \frac{ - 5x}{ - 5} = \frac{ - 55}{ - 5} [/tex]
[tex]x = 11[/tex]
[tex] - 5(11 - 10) { = }^{?} - 5[/tex]
[tex] - 5 \times 11 - 5 \times - 10 { = }^{?} - 5[/tex]
[tex] - 55 + 50 { = }^{?} - 5[/tex]
[tex] - 5 = - 5[/tex]

-2(3 + c) = 16
what is the value of c is a solution to the equation
Answer:
-11
Step-by-step explanation:
Simplify
Answer:
c=−11
Step-by-step explanation:
-2(3+c)=16
Divide both sides by -2
-2(3+c)/-2 = 16/-2
Simplify
3+c=-8
Subtract 3 from both sides
3+c-3=-8-3
Simplify
c=-11

18+ 0.50x=12 + 0.75x
Answer:
x = 24
Step-by-step explanation:
18 + 0.5x = 12 +0.75 x
18 - 12 = 0.75 x - 0.5x
6 = 0.25 x
24 = x
Answer:
x=24
Step-by-step explanation:
Need help ASAP thank you
Answer:
x = 14
Step-by-step explanation:
First put it into slope intercept form
20 = 2x - 8
Move the variable to the left hand side and change its symbol
-2x + 20 = -8
Move the constant to the right hand side and change its symbol
-2x = -8 - 20
Calculate the difference
-2x = -28
Divide both sides of the equation by -2
x = 14
Solution
X = 14

[tex]a^{2}[/tex] is just a*a, and [tex]a^{4}[/tex] is a*a*a*a
Thus, adding them together is a*a a*a*a*a, or [tex]a^{6}[/tex]
Alternatively, use the rule
[tex]a^{m} +a^{n} =a^{m+n}[/tex]
When used in this problem:
[tex]a^{2} +a^{4} =a^{2+4} = a^{6}[/tex]

A bracelet cost $36 after a 25% discount find the original price
Answer:
48
Step-by-step explanation:
Let original price be x
So we then reduce the price by 25%.
So what is 25% of x? Well, 25% is 25 percent. PERCENT is Latin: PER CENT....out of 100. So 25 out of 100 is 25/100 --> 0.25.
So 0.25 of x means 0.25x. This is the amount we took off, to reduce the price.
So we had ORIGINAL less REDUCTION = new price
--> x - 0.25x = 36
--> 1x - 0.25x = 36
--> 0.75x = 36
--> x = 36/0.75
--> x = 48
Tell me if i am wrong?
If a bracelet cost $36 after a 25% discount, the original price of the bracelet will be $ 48.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol. The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages.
Given that, a bracelet cost $36 after a 25% discount
We have to find the original price of the bracelet,
Suppose the original price of the bracelets is x,
x - 0.25x = 36
1x - 0.25x = 36
0.75x = 36
x = 36/0.75
x = 48
Thus, if a bracelet cost $36 after a 25% discount, the original price of the bracelet will be $ 48.

Answer:
Point of intersection of diagonal is: (-4,2)
x-coordinate = -4
y-coordinate = 2
Step-by-step explanation:
The diagonals of parallelogram bisect each other, So we need to find the midpoint of the diagonal to find the point of intersection. The midpoint of both diagonals will be same.
Consider the diagonal BD
We have B (-6,-5) and D (-2,9)
We need to find midpoint of the diagonal BD.
The formula used is: [tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
We have [tex]x_1=-6, y_1=-5, x_2=-2, y_2=9[/tex]
Putting values and finding midpoint
[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint=(\frac{-6+(-2)}{2},\frac{-5+9}{2})\\Midpoint=(\frac{-6-2}{2},\frac{-5+9}{2})\\Midpoint=(\frac{-8}{2},\frac{4}{2})\\Midpoint=(-4,2)[/tex]
So, We get Midpoint(-4,2)
We will get the same midpoint if we find for other diagonal AC.
So, Point of intersection of diagonal is: (-4,2)
x-coordinate = -4
y-coordinate = 2

brad buys a pack of 12 bottles for £9.25
he sells all the bottles for £1 each
work out brads percentage profit
Answer:
29.87%
Step-by-step explanation:
£9.75 \ 12 = £0.77
This is what he pays for each bottle
He makes £0.23 on each bottle sold
0.23/0.77 x 100 = 29.87
This is the percentage profit.
You can also validate the answer by calculating 29.87% of £0.77 and then add it to the £0.77 and you will see that you get £1
