(2y + x) + (2y + x) = (-2y + x) + (2x - 15)
2y + x + 2y + x = -2y + x + 2x - 15
4y + 2x = -2y + 3x - 15
+2y + 2y
6y + 2x = 3x - 15
-2x -2x
6y = x - 15
+15 +15
15 + 6y = x

Step-by-step explanation:
The school bought 16 calculators
Let's use a simple way. SPOE, APOE, DPOE, MPOE.
First, isolate the variable.
x5 + 3 = 2
-3 -3
x5 = -1/5 (5 divided by -1)
Answer to 5 divided by -1: -5.
A is the answer. (I'm pretty sure.)
If you need further help on steps, feel free to ask by replying.
~Realistic
A=x
B= 2x
C=3x
If you add them up =
6x =180
÷6 both sides
x=30
A=30
B=60
C=90
one angle is 90 degrees so the triangle is classified as a right triangle

<h3>Radius:</h3>
radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
<h3>Diameter:</h3>
2 times the radius is the circle's diameter.
<h3>Circumference:</h3>
The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).
