Answer:
2000 dollars
Step-by-step explanation:
let's say each boy gets x dollars
each girl gets 100 more dollars than each boy, or 100+x dollars
money = total money amongst boys = x dollars for each boy = 5 * x as there are 5 boys
money = total money amongst girls = 100 + x dollars for each girl = (100+x) * 4 as there are 4 girls
set the two equal to each other
5*x = (100+x) * 4
expand
5x = 400 + 4x
subtract 4x from both sides to put all the variable terms on one side
x = 400
each boy gets 400 dollars
total money = 5 *x = 2000 dollars
The equation for the line is x= -4 because your line is going through the x axis
Answer:
10-B, 9-C, 11-D, 12-A
Step-by-step explanation:
D. You can tell by the opened and closed line dots.
To find this answer, take both sides of the equality and square them:
(√ײ)=9²
This gives you:
×=81
