2(c-3)=s
because you have to subtract 3 years from sherman's age first, so you need the parentheses
X/4 + 1 = -6
x/4 = -6 -1
x/4 = -7
x= -28
Answer:
Example
Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
Step 2 SOHCAHTOA tells us we must use Cosine.
Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
Step 4 Find the angle from your calculator using cos-1 of 0.8333:
Boys:girls = 4/5
boys = 4/(4+5) = 4/9 of the class
Y= (x(9/5)) + 32; Ex: y=(100(9/5)) + 32 —> 100 x 1.8 (or 9/5) = 180–> 180 + 32= 212 F
