Answer:
B
Step-by-step explanation:
1) lets use elimination to solve this:
multiply 10x+4y=24 with 3 in order to get "4y" into "12y"
3(10x+4y=24)
30x+12y=72
now subtract both equations to eliminate 'y"
30x+12y=72
-
6x+12y=48
---------------------
24x=24
x=1
now substitute 1 in the above equation:
6(1)+12y=48
6+12y=48
12y=42
y=7/2
Answer:
50 m/s
250 m
Step-by-step explanation:
180 km/hr × (1000 m / km) × (1 hr / 3600 s) = 50 m/s
50 m/s × 5 s = 250 m
Answer:
angles 3 and 4 both equal a 90 degree angle or bisect a 90 degree angle.
angle 5 is 44-degrees because it is complementary or vertical to the 44 degree angle.
x=32 because it is on the same line as the 44-degree angle and a line is 180 so 180-44=136 and to get the rest of x you would do the equation backwards so 136 divided by 4 is 34 and 36-2=32
angle a is 136 described above.
angle b, because it is on the same line as the 46 degree angle is 180-46=134
now im pooped :(
