1/3 + 3/7
save + fun + extra

(7/21 + 9/21) = 16/21 on save and fun

Marshall divides his money into four categories.

He saves 1/3 of his money.

He gives 1/6 of his money to a charity.

He uses 1/14 of his money to buy snacks at school,

and he spends 3/7 of his money on fun.

Money he saves = \frac{1}{3}

Money he spends for fun = \frac{3}{7}

Fraction of his money he save and spend on fun = \frac{1}{3} + \frac{3}{7}

LCD of (3 and 7) is 21

\frac{1*7}{3*7} + \frac{3*3}{7*3}

\frac{7}{21} + \frac{9}{21}

Denominators are same so we add the numerators

\frac{16}{21}

Help guys<br>make p da subject of the formula<br>​
Basile [38]

Answer:

p=\dfrac{m}{k-s}

Step-by-step explanation:

When they ask you to make a variable the "subject of the formula", they're basically asking you to build a "machine" for it. In the expression y=mx+b, for instance, if we know what m, x, and b are, we can plug them all in and out comes a value for y! To build that machine, we need to get it by itself on one side of the equation.

So, we want to build this machine for p, and the equation we have to build it out of is

1=\dfrac{pk}{m+sp}

One think we can immediately say about this equation: for a fraction to be equal to one, its numerator and denominator have to be equal to each other. So we can say

m+sp=pk

Ok, what next? Well, if we want p by itself, we need to somehow peel it off of that <em>sp</em> and <em>pk</em>. Let's collect them on the right side by subtracting <em>sp </em>from both sides:

m=pk-sp

p is a <em>common factor</em> of both <em>sp </em>and <em>pk</em>, so we can peel it away using the distributive property:

m=p(k-s)

And from here, we can divide both sides by k-s and we'll have p as our subject:

\dfrac{m}{k-s}=p or p=\dfrac{m}{k-s}

So if we know m, k, and s, we can easily solve for p. If m = 4, k = 2, and s = 0:

p=\frac{4}{2-0} =\frac{4}{2}=2

Answer:

The measure of the fourth angle = 137.1°

Step-by-step explanation:

Let x = the measure of the fourth angle

Sum of all 4 interior angles in a quadrilateral equal 360°

so

x + 23.5° + 99° + 100.4° = 360°

x + 222.9° = 360°

              x = 360° - 222.9°

              x = 137.1°
