When ever I encounter problem like this, I make the equation become:
z = anything buy z.
First, you want to get 2/5 to the other side, to do so, you need to multiply 5/2 on both side. then you are left with z+1=5/2 y. Then you subtract 1 from both sides to make z on its own. The answer should be z = 3/2y or z= 1
y
2/5(z+1)=y
2/5(z+1)5/2=5/2y
z+1=5/2y
z+1-1=5/2y-1
z=3/2y or z=<span>1
y</span>
The answer is C. 3×4 = 12. There are two therefore 50-24 = 26.
13987.17=p(1+0.032/2)^2*7
Solve for p
P=13,987.17÷((1+0.032÷2)^(14))
P=11,199.99
0.09 in scientific notation is 9.0x10^-2

Answer:
A1) 125
A2) 47.5%
B) 30
Step-by-step explanation:
Remember 'of' in this sentence means times(*). % shows a certain number/100.
a1) 48% 'of' what number is 60?
(let unknown number be x)
48/100 *x=60
Solve the equation, and the answer is x=125
a2) what percentage 'of' 120 is 57?
(let the unknown percentage be x)
(x/100)*120=57
x=47.5%
b) 24 students= 80% of the total number of students
1%=24/80
100% of the total number of students=30
So, there are total of 30 students
