Answer:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Step-by-step explanation:
If vertical angles are congruent you know
84=4x
21=x
You also know that angle M is supplementary to the angle
, measuring 84. Supplementary means it adds to 180 so if you take the difference you get
180-84=M
96=M
Also M is vertical to the last unknown angle so since vertical angles are congruent the last angle is also 96
Well it's a cube all sides should be the same size therefore 7 cm as it already says
So F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40
1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph
Answer:
Step-by-step explanation:
if you need to add 2 fractions
20/4+ 8/3
common denominator is 12
60/12+32/12=92/12= 7 8/12 =7 2/3
