If h=4, then 5(4)+7= 27. Using PEMDAS, do multiplication first, so 20, then add the 7.
Answer:
5%
Step-by-step explanation:
You want to find r when ...
I = Prt
is equal to P and t=20.
P = Pr·20 . . . . fill in the problem values
1/20 = r = 0.05 = 5% . . . . divide by 20P
The simple interest rate is 5%.
Answer:
4/9
Step-by-step explanation:
Ratio of boys = 4
Ratio of girls = 5
1. When illustrating ratios in fraction, you add the ratios
4 + 5 = 9
2. Next you put the boys ratio over the total ratio
4/9
3. Sometimes it can be reduced to a lower form eg. 5/10 can be reduced to
1/2.
Answer:
30
Step-by-step explanation:
you have to devide the total amount they paid with the number of books.. 2550÷85=30
Step-by-step explanation:
Equ of line -
y=mx+c
Using point (3,-1)
3 as x, - 1 as y
M=2/3
Substitute the values of these coordinates
3=2/3(-1) +c - - - - now find for c
c= 3- (-2/3)
c= 3.67
Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with
y=2/3x + 3.67
