Answer: Subtract

Step-by-step explanation: Make your denominator equal using the concept of LCM, then subtract the numerators accordingly. Rewrite each fraction to its equivilent fraction with a denominator equal to the LCM=30, then you need to subtract the numberators, but make sure to reduce your answer to the lowest possible term. I hope this helps.

How do you convert fractions into decimals
mixer [17]

Let's say we have the fraction \frac{1}{2}

For instance, in the case of the fraction: " 1/2" ; the denominator is ' " 2 " . If the denominator is 2, we must divide 2 by our numerator which is 1 so we will create a divison problem and it will be 1 ÷ 2 = 0.5

↑ This method will always work ↑

The volume of a gas in cubic centimeters v,varies inversely with the pressure of the gas in liters per square centimeters,p when
scoundrel [369]

Answer:

The volume of the gas is 145.45\ cm^{3}

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

Let

v------> the volume of a gas in cubic centimeters

p-----> the pressure of the gas in liters per square centimeters

so

p*v=k

we have

v=16\ cm^{3}, p=20\ l/cm^{2}

substitute and solve for k

k=16*20=320

The equation is p*v=320

<em>Find  the volume of the gas when the pressure is 2.2 L/cm2</em>

so

For p=2.2\ l/cm^{2} Find the value of v

substitute in the equation

(2.2)*v=320

v=320/2.2=145.45\ cm^{3}

The sides of a triangle are (x+5), and (x+8) units. Find the value of x if the perimeter of the triangle is 106 units.
lutik1710 [3]
106=x+x+5+x+8

106=3x+13

3x=93

x=31

(the sides are 31, 36, 39 respectively)
