37.5 = initial rate
44.9 = slope/rate
In problems like these, just use y = initial rate + rate(variable)
In this case, the answer would be y = 37.5 + 44.9h
She started with 60 pennies
<h3>Ratios and propotions</h3>
Let the number of a bunch of pennies she has to be "x"
If she gives 1/3 of her pennies to her older brother, she will have 2/3 x remaining
If she gives 2/5 of her remaining pennies to her younger sister, she will have 2/3x- (2/5 of 2/3x) = x remainijg
If Sally has 24 pennies remaining, then;
2/3x - 4/15x = 24
10x-4x/15 = 24
6x/15 = 24
6x = 15 * 24
x = 60
This means that she started with 60 pennies

Answer:
0.35
Step-by-step explanation:
7 over 20 = 7/20=35/100=0.35
<em>Answer,</em>
<em><u>X = 3/4</u></em>
<em>Explanation,</em>
<u><em>Step 1: Simplify both sides of the equation.</em></u>
<em>3.25 + 0.5x + (1)(1)/3 + 5/6x = (5)(11)/12</em>
<em>3.25 + 0.5x + 1/3 + 5/6x = 55/12</em>
<em>(</em><em>0.5x + 5/6x</em><em>) + (</em><u><em>3.25 + 1/3</em></u><em>) = 55/12 (Combine Like Terms)</em>
<em>4/3x + 3.583333 = 55/12 </em>
<em>4/3x + 3.583333 = 55/12</em>
<u><em>Step 2: Subtract </em></u><u><em>3.583333</em></u><u><em> from both sides.</em></u>
<em>4/3x + 3.583333 − 3.583333 = 55/12 − 3.583333 </em>
<em>4/3x = 1</em>
<u><em>Step 3: Multiply both sides by </em></u><u><em>3/4.</em></u><u><em> </em></u>
<em>(3/4) * (4/3x) = (3/4) * (1)</em>
<em>x = 3/4</em>
