Hello,
x= first number
y= second number
their sum is 56, so:
x+y=56
The first number is 2/5 of the second number, so:
Those are the two equations.
Answer:
bots/total = 3/8
Step-by-step explanation:
There are 15 girls and 9 boys
15+9 = 24 total students
boys/total = 9/24
Divide the top and bottom by 3
= 3/8
Answer:
y=-1/3x-5
Step-by-step explanation:
y=mx+b is equation of line where m is slope and b is y-intercept.
From question statement, we observe that
m= -1/3 , b= -5
put above values in equation of line, we get
y= -1/3x-5.
Answer:
1,020
Step-by-step explanation:
First step.
Since he can read 21 1/4 pages in 1 and 1/4 hour then we got to know how many pages he can read in one hour right? so we need to divide.
Second step.
So we will need to divide 21 1/4 divided by 1 and 1/4 which will give us 17 which is the pages he will read in one minute.
Third step.
After you get that then we multiply it by the hour which is 60 minutes in an hour so,
60 x 17 = 1,020
Which gives us the answer
Hope that helps =)
