Answer:
Step-by-step explanation:
12/5
as a mixed fraction 2 2/5
or as decimal 2.4
Answer: 48
5+8=13
78 divided by 13 equals 6
6 x 8(long side)=48
Step-by-step explanation:
Ratio of girls : boys = 5 : 4
<u>Find total parts:</u>
Total parts = 5 + 4 = 9
<u>Find 1 part:</u>
9 parts = 36
1 part = 36 ÷ 9 = 4
<u>Find 5 parts (Girls):</u>
Girls = 5 parts = 4 x 5 = 20
Answer: There are 20 girls.
First of all, we need to find the slope of the given line, writing it in the 
form and reading the 
coefficient:
So, the slope is 
If a line with slope 
is perpendicular to a line with slope , the following relationship holds:
So, the slope of our line must satisfy
So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope and a point 
of a given line, its equation is given by
So, if you plug your values, you have
