Answer: y = 7.5
Step-by-step explanation: To solve for <em>y</em> in this equation, we want to get <em>y</em> by itself on the left side of the equation.
Since <em>y</em> is being multiplied by 4, to get <em>y</em> by itself, we need to divide by 4 on the left side of the equation. Since we divided by 4 on the left side, we must also divide by 4 on the right side.
On the left side, the 4's cancel out so we're simply left with <em>y</em>. On the right side, we have 30 divided 4 which is 7.5.
So we have <em>y = 7.5</em>.
Answer:
n = 1.2
Step-by-step explanation:
3n = 3.6
Divide both sides by 3 to get n by itself.
3.6/3 = 1.2
n = 1.2

Here. Tell me if you don't understand my writing.
Answer: Line R and Line P are perpendicular because they intersect at a point and create a pair of equal angles.
Step-by-step explanation:
Volume of the candle:
V = B * h ( where B is the base area and h is the height )
270 = B * 18
B = 270 : 18
B = 15 cm²
B = a * b / 2
B = 5 * b / 2
15 = 2.5 b
b = 15 : 2.5
b = 6 cm
Therefore dimensions of the box are: a = 7cm, b = 6 cm, c = 18 cm.
Answer: B ) 7 by 6 by 18 cm.
