From the number 842 to 109 is a decrease of 733. so 109 minus 733 will result in a -624.
2 160 = 320
5 X 1 5
Then you go 320 divided by 5 which is 64cm thick.
Disagree. Even though it has no b it is still a line but a horizontal line. It will be at 7 on the y- intercept but horizontal.
Answer:
1:3
Step-by-step explanation:
First, you need to make a system of equations for the situation.
Let G represent the number of girls and B represent the number of boys.
Since there are twice as many girls as boys,
G = 2B
There are a total of 30 students in class so,
G + B = 30
or
G + B = TOTAL
In order to find the ratio of BOYS to the TOTAL STUDENTS,
you plug in B values that make up G.
(2B ) + B = TOTAL
3B = TOTAL
B = TOTAL / 3 or (1/3) TOTAL
Since B is one third of the total number of students, the ratio is 1:3.
