Answer:
Micaela is 17
Step-by-step explanation:
s+2=m
(s+2+4)+(s+4)=40
(s+6)+(s+4)=40
2s+10=40
40-10=30
2s=30
30/2= 15
s=15
{s+2=m}
15+2=m
m=17
Answer:
205-160=<em>d</em>
Step-by-step explanation:
Answer:
Adults= 110
Children= 340
Step-by-step explanation:
Given data
let adults be x
and children be y
x+y= 450----------1
2x+y=680---------2
from 1
x= 450-y
put this in 2
2(450-y)=680
900-2y=680
900-680=2y
220=2y
y= 220/2
y= 110
x+110= 450
x= 450-110
x=340

Step-by-step explanation:
<h3>
Answer:</h3>
y=1/2x
<h3>
Solution:</h3>
- The slopes of perpendicular lines are opposite reciprocals of each other.
- The simplest way to determine a number's reciprocal is to flip it over, like so:

- Now, change the sign:

- So we have the <em>slope </em>of the line that's <em>perpendicular </em>to the given line.
- Now, let's find the line's equation.
- First, let's write it in Point-Slope Form:
- y-y1=m(x-x1)
- y-(-2)=1/2(x-4)
- y+2=1/2x-2 (Point slope)
- Now, convert to slope-intercept:
- y=1/2x+2-2
- y=1/2x
