D=6h
The distance equals 6 (since you're running 6mph) times 'h' amount of hours.
Answer:
x = -4
, y = -6
Step-by-step explanation:
Solve the following system:
{y = -5 x - 26 | (equation 1)
5 y = 3 x - 18 | (equation 2)
Express the system in standard form:
{5 x + y = -26 | (equation 1)
-(3 x) + 5 y = -18 | (equation 2)
Add 3/5 × (equation 1) to equation 2:
{5 x + y = -26 | (equation 1)
0 x+(28 y)/5 = (-168)/5 | (equation 2)
Multiply equation 2 by 5/28:
{5 x + y = -26 | (equation 1)
0 x+y = -6 | (equation 2)
Subtract equation 2 from equation 1:
{5 x+0 y = -20 | (equation 1)
0 x+y = -6 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -4 | (equation 1)
0 x+y = -6 | (equation 2)
Collect results:
Answer: {x = -4
, y = -6
Answer:
...
Step-by-step explanation:
1.) if supplement then its equal to 90, so subtract from 90
2.) 90-72= 18, so the asnwer is 18
39+2x+1=90
40+2x=90
2x=50
x=25
3.) x-24+29=296
x+5=296
x=291
4.)vertical angles so congruent, 107
5.) 83+4x+1=180
84+4x=180
4x=96
x=24
Answer:
y = 0.55 or 5 / 9
Step-by-step explanation:
here's the solution :-
=》y + 7 = 19y - 3
=》7 + 3 = 19y - y
=》18y = 10
=》y = 10 ÷ 18
=》y = 5 ÷ 9
=》y = 0.55
This would be:-
square root [ (5-0)^2 + (-9 -3)^2) ]
= square root ( 25 + 144)
= sqrt 169
= 13 Answer
