Answer:
2A/h = b
Step-by-step explanation:
A= (1/2)(b)(h)
Multiply each side by 2
2A = 2*1/2 *b*h
2A = bh
Divide each side by h
2A/h = bh/h
2A/h = b
Step-by-step explanation:
d = the distance in one direction.
the time t1 it took group 1 was
t1 = d/6 + d/4
and t2 for group 2 moving with speed2 all the way
t2 = (d+d)/speed2
we know
2d = 24 miles
d = 12 miles
t1 = t2
so,
12/6 + 12/4 = 24/speed2
2 + 3 = 24/speed2
5 = 24/ speed2
5×speed2 = 24
speed2 = 24/5 = 4.8 mph
the second group moved with 4.8 mph.
Answer:
y=9
x=26
Step-by-step explanation:
5x-17+3x-11=180
8x-28=180
8x=208
x=26
5(26)-17
130-17
113
2y+5+90=113
2y+95=113
2y=18
y=9
M=1.53 -> Multiply 5.1 by .3 and you find m.
I didn't get the question whether it was 42 or 4×2
