You can solve it by replacing the Y in the 2nd equation with the solved Y in the first.
4x + 2(3x-15)= 22
that should give you...
4x + 6x - 30 = 22
then combine like terms...
10x - 30 = 22
now we need to get X alone so add 30 to each side....
10x = 52
now divide both sides by 10..
X = 52\10
both are divisible by 2...
X = 26\5
you should be done unless you need Y as well then go back to the first and plug in what you found for X...
Y = 3(26÷5)- 15
and that should give you Y.
a 2nd method you can make your own answer by making x = 0 ..
Y= 3(0) -15
Y= -15
now put that in the 2nd for Y...
4x+ 2(-15) = 22...
4x-30= 22
add 30 to both sides..
4x = 52
divide by 4....
X = 13
now take this to the first for x...
Y= 3(15) - 15
Y = 30
you can check your work by plugging in the two on top and see if the final is the same..
30 = 3(15) - 15
the 2nd way is faster though of course..
anyway X= 13 Y= 30
The '2.5/10' part means a 2.5% discount is available if paid within 10 days. (2.5% = 0.025)
Amount of the discount:
($1,500 x 0.025) = $37.50
Amount needed to pay within 10 days is ($1,500 - $37.50) = $1,462.50
hope it helps
Answer:
Step-by-step explanation:
The triangle KLM is shown in the attached photo. The sum of the angles in a triangle is 180 degrees. It means that
angle K + angle L + angle M = 180 degrees. Since
m angle K=(10x+10). m angle L=(9x-3). m angle M=(7x-9), then
10x + 10 + 9x - 3 + 7x - 9 = 180
10x + 9x + 7x = 180 + 9 + 3 - 10
26x = 182
x = 182/26
x = 7
m angle K=(10x+10) = 10×7 + 10 = 80 degrees
m angle L=(9x-3) = 9×7 - 3 = 60 degrees
m angle M=(7x-9) = 7×7 - 9 = 40 degrees.
The triangle is an acute triangle because each angle is lesser than 90 degrees
The triangle is scalene triangle because non of the sides are equal.
The correct answer is 1/11
Answer: $13
Step-by-step explanation:
From the question, we divide the number of 362 roles by the amount sold.
That is if 362 roles = $4706
1 role = $4706/362 = $13
1 role costs $13
