Answer:
65%
Step-by-step explanation:
Given data
Original price= 180AED
Selling price= 63AED
Required
% decrease
The expression for the decrease
% decrease= (original-selling)/original *100
subsitute
% decrease= (180-63)/180 *100
% decrease= 117/180 *100
% decrease=0.65 *100
% decrease=65%
Hence the percent decrease is 65%

Find the slope of a line perpendicular to the equation 3x-y=6
Answer:
[tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
The slope of a line perpendicular to a line is the negative reciprocal of the slope of the line given.
The equation of the line is:
[tex]3x-y=6[/tex]
[tex]y=3x-6[/tex]
The slope of this line is 3.
Thus the negative reciprocal would be [tex]-\frac{1}{3}[/tex]
Find the slope that passes. through the two points (5-8 and (4,6)
Answer:
-14
Step-by-step explanation:
Line is passing through the points (5, -8) and (4, 6).
Therefore,
[tex]slope = \frac{ - 8 - 6}{5 - 4} \\ \\ = \frac{ - 14}{1} \\ \\ = - 14[/tex]
An angle measures 68.4° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
x + x + 68.4 = 90
2x + 68.4 = 90
-68.4 -68.4
2x = 22
/2 /2
x = 11 first angle
x + 68.4 = 11 +68.4 = 79 degrees second angle

Poppy has one bag of beads. She is going to make three difference necklaces.
For the first necklace, she needs 3/8 of a bag of beads. For the second, she
needs 1/8 of a bag of beads. For the third, she needs 5/8 of a bag. What
fraction of a bag of beads does she need? Does she have enough? Explain.
Answer:
9/8 of a bag
she doesn't have enough beads.
Step-by-step explanation:
Bag of bead poppy has = 1
Bag of bead needed for necklace 1 = 3/8 of a bag
Bag of bead needed for necklace 2 = 1/8 of a bag
Bag of bead needed for necklace 3 = 5/8 of a bag
Total bag of beads needed = 3/8 + 1/8 + 5/8
= (3+1+5)/8
= 9/8
She needs 9/8 of a bag of bead
9/8 = 1 1/8
Therefore, she doesn't have enough beads.

Answer:
Slope is equal to the change in y over the change in x , or rise over run.
m=change in y/ change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=0−(2)/9−(5)
Simplify.
m=−12

I need help ASAP help me answer questions and then I put a picture up
Answer:
(-4,9)
Step-by-step explanation:
To solve the system of equations, you want to be able to cancel out one of the variables. In this case, it'd be easiest to cancel out the x variables. To do this, you'll want to multiply everything in the first equation by 2 (2(x-5y=-49)=2x-10y=-98). Then, you can add the two equations together. 2x and -2x will cancel out, so you'll be left with -11y=-99. Next, solve for x by dividing both sides of the equation by -11, which will give you y=9. This is your y-coordinate! At this point, you're halfway to the answer as you just need your x-coordinate. It's not too difficult to find the x-coordinate, since you just substitute 9 into one of the equations. It doesn't matter which one you choose as you should get the same answer with both. I usually substitute the y-value into both equations, though, just to make sure I'm correct. Once you put the y-value into the equations, you should get x=-4 after solving it. :)

Answer:
∠S = 151°
Step-by-step explanation:
Hello there!
This is an irregular pentagon
If you didn't know the sum of the interior angles add up to equal 540
We must solve for x to be able to find the measure of angle S
we can use this equation to solve for x
540 = 5x + 2 + 10x - 3 + 7x - 11 + 13x - 31 + 8x - 19
step 1 combine like terms
2 - 3 - 11 - 31 - 19 =-62
5x + 10x +7x + 13x + 8x = 43x
so now we have
540 = 43x - 62
step 2 add 62 to each side
-62 + 62 cancels out
540 + 62 = 602
now we have
602 = 43x
step 3 divide each side by 43
43x/43 = x
602/43=14
we're left with x = 14
Now we want to plug in x for angle S
13(14) - 31
13*14=182
182-31=151
So we can conclude that the measure of angle S is 151 degrees
