To compare fractions , you need to have same denominator.
Just multiply the Numerator and denominator of the fraction by required number so as to get the common denominator.
for example, In this case , the common denominator is 12.
the first fraction is converted as shown, 5/3=5*4/3*4=20/12
similarly, you can convert others.
Once you have common denominator, just compare numerators.
Answer:
look at the picture for the answer
Hint: the sum of the angles is equal to 180 in a triangle. could you make an equation to use that?
3x+13, 7x+2, and 75 are the three angle values. They will sum up to 180.
Steps:
We set the equation to:
3x+13+7x+2+75=180
We can combine some terms
10x+90=180
Then, we isolate x
10x=90
And we divide by 10
x=9
Great! but we are not done yet. We want the measure of angle A, so we need to plug x back into the equation for angle a
3(9)+13
Multiply
27+13
Add
40
68.181 mph
300 feet/3 seconds = 100ft/sec
100ft x 60 sec. =6000ft/min
6,000 x 60= 360,000ft/hour
then convert to miles
