75% of students = 18
Divide by 3 to find 25% of students.
25% of students = 6
Add the two together or multiply the 25% of students by 4 to get the total number of students.
25% + 75% = 6 + 18 = 24 students
or
25%*4 = 6*4 = 24 students
The second one. It is the same as the original.
Y=<span><span>−<span>3x</span></span>−<span>2
</span></span>-3x=y+2 (keep, change, flip)
so....
-3x-2 :) Hope I helped!
Answer:
Step-by-step explanation:
You want to set up a system. We are given some points fo we can set up inputs and outputs. F(0) = 5, given by point (0,5). and F(3)=135, given by point (3,135). The exponential function general equation is F(x)= a(b)^x. plug in out functions into the general equation to get a(b)^0=5 and a(b)^3=135. Then you simplify and solve for a. In the equation a*b^0=5, anything to the power of 0 is 1. so a*1=5. Therefore a=5. we plug in the a to the second equation to find b. 5*b^3=135. b^3=27. b=3 from simplifying. Therefore, the equation should be 5(3)^x. THATS IT!
Answer:
Step-by-step explanation:
n = 25
33+n = 33+25 = 58
n/5 = 25/5 = 5
