(58*13)15 - 20+ 48^2
Answer:
13,594
Step-by-step explanation:
Parentheses
Exponets
Multiply
Divide
Add
Substract
You follow the list in order so you would do the parentheses first and then the exponets and so forth. This is how I got my answer:
(58*13) * 15 - 20 + 48^2 - solve what's in the parentheses first
754 * 15 - 20 + 48^2 - then solve the exponet
754 * 15 - 20 + 2304 - next you solve the rest of the problem from left to right, in that case, I would multiply
11310 - 20 + 2304 - then I would subtract
11290 + 2304 - finally i would add
13594 - This would be my answer
I hope this helps :) Have a nice day!

Simplify the Ratio 25: 35
Answer:
I believe the answer to this ratio would be 5:7.
Step-by-step explanation:
This is the ratio because we can simplify the ratio 25 : 35 by dividing both terms by the greatest common factor (GCF).
The GCF of 25 and 35 is 5.
Divide both terms by 5.
25 ÷ 5 = 5
35 ÷ 5 = 7
Therefore:
25 : 35 = 5 : 7

8(5x+ 2) = 296 how to solve this
Answer:
x = 7
Step-by-step explanation:
8(5x + 2) = 296
40x + 16 = 296
40x = 280
x = 7
Answer:
x=7
Step-by-step explanation:
➼Okay, so first thing you need to do is to distribute the 8 to everything in the parentheses:
8(5x+ 2) = 296
8 times 5x
8 times 2
(8 x 5x) + (8 x 2) = 40x + 16
➼Now you solve for x
40x+16=296
➼to get rid of 40 you have to do the opposite and divide it by everything
40x+16=296
40/40=0
16/40=0.4
296/40=7.4
➼all adds up to x + .4 = 7.4 but to get the x alone you need to get rid of the .4, we'll do this by doing the opposite and subtract it from everything
.4-.4=0
7.4-.4=7
➼so in conclusion
x=7
Jethro is looking at a tablet priced £282. How much would Jethro save if he bought 3 tablets for work with a discount of 1/4 off the original price?
Hello :D
£282 x 3 = £846
£846/4 = £211.50
£846 - £211.50 = £634.50
He would save £211.50 and it would cost him £634.50 to buy the 3 tablets.

Two complex numbers are given, where m, n, p, and q are real numbers.
m+ni
p+qi
For what relationship among m, n, p, and q, will be the product of these two complex numbers have only an imaginary part?
This is Algebra 2.
Answer:
Given complex numbers:
m+ni p+qiTheir product is:
(m + ni)(p + qi) = mp + npi + mqi + nqi² = mp - nq + (np + mq)iIn order to have only an imaginary part we need:
mp - nq = 0or
mp = nqAnswer:
First we have to find product
[tex]\\ \sf\longmapsto (m+ni)(p+qi)[/tex]
[tex]\\ \sf\longmapsto m(p+qi)+ni(p+qi)[/tex]
[tex]\\ \sf\longmapsto mp+mqi+npi+nqi^2[/tex]
[tex]\\ \sf\longmapsto mp+mqi+nqi-nq[/tex]
[tex]\\ \sf\longmapsto mp-nq+(mq+nq)i[/tex]
We have to keep imaginary parts i.e Im(z)[tex]\\ \sf\longmapsto mp-nq=0[/tex]
[tex]\\ \sf\longmapsto mp=nq[/tex]
what is the answer to -|3x-9|+2=-4
entered :
-|3x-9|+2=-4
Step by step solution :
STEP
1
:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
-|3x-9|+2 = -4
Another term is moved / added to the right hand side.
To make the absolute value term positive, both sides are multiplied by (-1).
|3x-9| = 6
STEP
2
:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |3x-9|
For the Negative case we'll use -(3x-9)
For the Positive case we'll use (3x-9)
STEP
3
:
Solve the Negative Case
-(3x-9) = 6
Multiply
-3x+9 = 6
Rearrange and Add up
-3x = -3
Divide both sides by 3
-x = -1
Multiply both sides by (-1)
x = 1
Which is the solution for the Negative Case
STEP
4
:
Solve the Positive Case
(3x-9) = 6
Rearrange and Add up
3x = 15
Divide both sides by 3
x = 5
Which is the solution for the Positive Case
STEP
5
:
Wrap up the solution
x=1
x=5
I hope this help you
Answer: x= 1, 5
Step-by-step explanation:
First, isolate the absolute value. Subtract two from the equation to get -l3x-9l=-6, and then divide by -1 to get l3x-9l=6.
Since an absolute value measures how far away a value is from zero, it's always positive. For example, -10 and 10 have the same absolute value, 10, because they're both 10 units away from zero.
Because of this, you create two equations; 3x-9=6, and 3x-9=-6.
For the first equation, add 9 to 6 and divide that by 3 to get x=5.
For the second equation, add 9 to -6 and divide that by 5 to get x=1.
Your friend claims there is an easier way to find the length of a segment than the Distance Formula when the x-coordinates of the endpoints are equal. He claims all you have to do is subtract the y-coordinates. In the image above, this would be like two hot air balloons directly in line with each other with one below and one above. Do you agree with his statement? Explain your reasoning. You may include an image, a graph, or work to help support your argument
Answer:
The statement is not correct.
Simply subtracting the [tex]$y$[/tex]-coordinate does not ensure that we will have a nonnegative result.
Step-by-step explanation:
Given
To find the length of a segment than the Distance Formula when the x-coordinates of the endpoints are equal. He claims all you have to do is subtract the y-coordinates.
Step 1 of 2
Your friend is not correct.
We shall take note that distances are nonnegative.
Simply subtracting the [tex]$y$[/tex]-coordinate does not ensure that we will have a nonnegative result.
Step 2 of 2
[tex]A B &=\sqrt{\left(x_{1}-x_{2}\right)^{2}+\left(y_{1}-y_{2}\right)^{2}} \\[/tex]
[tex]&=\sqrt{(x-x)^{2}+\left(y_{1}-y_{2}\right)^{2}} \\[/tex]
[tex]&=\sqrt{0+\left(y_{1}-y_{2}\right)^{2}} \\[/tex]
[tex]&=\sqrt{\left(y_{1}-y_{2}\right)^{2}} \\[/tex]
[tex]A B &=\left|y_{1}-y_{2}\right|[/tex]
Therefore, if the [tex]$x$[/tex]-coordinate of the endpoints are the same, then we can proceed by taking the absolute value of the difference of the [tex]$y$[/tex]-coordinates to find the length of the segment.

Carolina and Patricia received their Christmas bonus and decided to use this weekend to buy their Christmas gifts .
Carolina decided to take advantage of the Great Winter Sale in Liverpool that offers discounts of 50% + 20%.
Patricia went to the mall and took advantage of the boutique discount that offers discounts of 70%.
They both bought 3 items with a total listing price of $120. At the end of their purchase rounds, they will have coffee with their friend Cristina and tell her about the offers they found. Based on their experiences, Cristina must decide where she will do her shopping.
Analyze this situation and think,
Where would you recommend Cristina to do her shopping? What is the final price paid on each establishment?
Applying what you have seen in your math classes, what where your calculations and how you can relate it to composition of functions.
Answer:
I would recommend Christina to do her shopping at any of those 2 places because they both have a discount of 70%. The final price paid on each establishment was $36.
120*0.7 = 84
120 - 84 = 36
Step-by-step explanation:
Carolina has a discount of 50%+20% which is the same as a discount of 70%, and Patricia had a discount of also 70%, so they both had the same discounts.
Solve for the value of x by applying the definitions of complementary and supplementary angles
9514 1404 393
Answer:
x = 52
Step-by-step explanation:
The square corner symbol indicates the sum of the marked angles is 90°. (They are complementary.)
(x +3)° +35° = 90°
x° = 90° -38° = 52°
x = 52
which equation can be used to solve for X in the following diagram
Answer:
Equation AStep-by-step explanation:
Thus;Vertically opposite angles are equal according to the question.So;60⁰ = ( x + 45⁰)60⁰ - 45⁰ = x15⁰ = x Therefore x is 15⁰ and when placed in place of x ,we will have the same 60⁰20 POINTS!! (see attached image)
