step by step explanation:
Jake brought a car = 1500rs
Jake sell the car = 1800
profit = sp-cp
so profit = 1800-1500 = 300
profit percent = gain/cp×100
profit percent = 300/1500×100
profit percent = 20% (double zero are cancel and 300 divided by 15)
2x + 5y= 10; (4,9)
Write answer in slope intercept form.
Answer:
y = 5x - 5/2xy + 79
Step-by-step explanation:
First we need to solve for m which is slope.
Subtract 5y from both sides
2x = 10 - 5y
Then divide each term by 2
2x/2 = 10/2 + -5y/2
Then simplify to the left
x = 10/2 + -5y/2
Then simplify the right side
x = 5 - 5y/2
Next we have to find the value of b using the formula y = mx + b
So
y = (5 - 5y/2) * x + b
y = (5 - 5y/2) * (4) + b
9 = (5 - 5(9)/2) * (4) + b
Rewrite
(5 - 5(9)/2) * 4 + b = 9
Simplify more
Multiply 5 by 9
(5 - 45/2) * 4 + b = 9
Multiply by 2/2 to write 5 as a fraction
5 * 2/2 - 45/2) * 4 + b = 9
Then combine 5 and 2/2
(5 * 2/2 - 45/2) * 4 + b = 9
Combine the numerator over the denom
5 * 2 - 45/2 * 4 + b = 9
Simplify the numerator
-35/2 * 4 + b = 9
Cancel the common factor of 2
-35 * 2 + b = 9
Multiply
-70 + b = 9
Move the terms without b to the right side
b = 9 + 70 > b = 79
Now we substitute all the values into y = mx + b
y = 5x - 5/2xy + 79
Ela is buying $110 chair. She has a coupon for 15% off. How much does she pay for the chair if sales tax is 6%?
Answer:
$99.11 dollars
Step-by-step explanation:
Given the following question:
$110 dollars for a chair...
15% off from a coupon...
Then a 6% sales tax....
[tex]\frac{15\times110}{100} =15\times110=1650\div100=16.5[/tex]
[tex]110-16.5=93.50[/tex]
The chair costs $93.50 dollars after the 15% off coupon.
Now the 6% sales tax:
[tex]\frac{93.5\times6}{100} =93.5\times6=561\div100=5.61[/tex]
[tex]93.5+5.61=99.11[/tex]
[tex]=99.11[/tex]
After the 15% coupon and the 6% sales tax, the chair will cost "$99.11 dollars."
Hope this helps.

please help now it kinda important i get it done soon or i cant go to a dance for my school tomorrow. im begging u ill give u 5 stars and a thanks and maby even a showt out thats how much this means to me.
Answer: 352496
Step-by-step explanation:
First, to find 20% of 440,620, you can multiply:
0.2 x 440,620 = 88,124
Then, to find the new weight of the ship, you can subtract the 20% that was just found (88,124) from the ship's original weight (440,620) to get:
440,620 - 88,124 = 352,496
Therefore, the ship's weight is now 352496.
I hope this helps!

Mathematics need help with this paper
Answer:
5. x = 39°
6. x = 46°
7. x = 24°
8. x = 19°
Step-by-step explanation:
5.
Base angles are the same due to it being an isosceles triangle
Sum of angles in triangle = 180°
2x + 2x + (x - 15) = 1804x + x - 15 = 1805x - 15 = 1805x = 195x = 396.
Angle VZW and XZW are supplementary, meaning that they add up to 180°
3x + 17 + (x - 9) = 1803x + 17 + x - 9 = 1804x + 8 = 1804x = 184x = 46°7.
Sum of angles in a straight line add up to 180°
(2x - 4) + (3x + 5) + (2x + 11) = 1802x - 4 + 3x + 5 + 2x + 11 = 1807x + 12 = 1807x = 168x = 248.
All angles add up to 90°
x + (x + 4) + (3x - 9) = 90x + x + 4 + 3x - 9 = 905x - 5 = 905x = 95x = 19-Chetan K

Parallel lines are preserved in which of the following types of transformations? 1. rotations II. reflections III. translations
Answer:
All of the above.
Step-by-step explanation:
Translation, reflection, and rotation are isometries, since they preserve length. Therefore translation, reflection and rotation are congruency transformations. Further if we only require that parallel lines be mapped onto parallel lines, we get the shears and stretches.
What is the next number in the sequence?6,12,24,48
A.72
B.96
C.108
D.112
E.124
Answer:
B. 96
Step-by-step explanation:
The pattern doubles for each number so 6 doubles to 12. 12 doubled is 24... ect
so to find the answer we just double 48 :
48 X 2 = 96
How does the graph of f(x) = (x − 9)4 − 3 compare to the parent function g(x) = x4?
Using translation concepts, we have that the graph of f(x):
Was shifted 9 units to the right and 3 units down.
The parent function is given by:
The translated function is given by:
The first transformation was that , thus, it was shifted 9 units to the right.
Then, 3 was subtracted from the function, which means that it was shifted down 3 units.

Answer:
90
Step-by-step explanation:
Firstly, you divide 108 by 6, since 108 can't be divided by 5, and 108 divided by 6 gives you 18. Then you multiply 18 by 5, which gives you 90. Boom.
Answer: the answer is 90

When the equation of a line is given in the form y = mx + b like this is, the slope is simply the m value!
The equation shows an unknown number. PLEASE ANSWER, QUICKLY.
Solution:
Note that:
Given equation: x ÷ 3/7 = 7/15Simplify the given equation to solve for x.
x ÷ 3/7 = 7/15=> x × 7/3 = 7/15=> 7x/3 = 7/15=> 7x = 7/5=> 35x = 7=> x = 1/5Check:
1/5 ÷ 3/7 = 7/15=> 1/5 x 7/3 = 7/15=> 7/15 = 7/15 (True)Hoped this helped!

Player Aled a baseball league in runs batted in for the 2005 regular season. Player B, who came in second to player A, had 18 fewer runs batted in for the 2005 regular
season. Together, these two players brought home 232 runs during the 2005 regular season. How many runs batted in did player A and player Beach account for?
CE
Player A had runs and player B had runs batted in for the 2005 regular season.
Answer:
ok so we trying to find out how many each batted so lets make this a system of equation
first we now that combined they are 232 so
a+b=232
then we now that b is 18 less then a so
a-18=b
the system of equation is
a+b=232
a-18=b
so we now what b is so we can just plug that in
a+a-18=232
2a-18=232
2a=250
a=125
then we can just plug this back in
125+b=232
b=107
a=125
b=107
