4x-2y=7 (1)
-3x+3y=10 (2)
3y= 3x+10
y= x+10/3 (3)
sub (3) into (1)
4x-2(x+10/3)=7
4x-2x-20/3=7
2x-20/3=7
+20/3 +20/3
2x= 41/3
x= (41/3) / 2
x= 41/6
sub x= 41/6 into (3)
y= 41/6+10/3
= 61/6
Therefore the point of intersection is (41/6, 61/6)
Answer:
∠F = 50°
Step-by-step explanation:
The sum of all three angles in a triangle = 180°
∠F = 180° - 30° - 100° = 50°
Answer:
BE = 39/5 or 7.8
Step-by-step explanation:
As <ABC = <DBE trigonometric function is angle BAC and angle BED
so sin (<ABC) = sin(<DBE) and AC and BC , BD and BE
so AC/AB = DE/BE = 13/BE = 5/3
So now we cross multiply
BE = 13 × 3 over 5
13 × 3 = 39
and over 5 means
39/5 = 7.8
Answer:
7. 17/99
for this one, you multiply your decimal by 100 to get you
100x = 17.171717..
then you subtract it from x = .171717 to get you
99x = 17
then you divide.
8. 0.5
The area of a square is the side length squared. You square root 0.25 to get you 0.5.
