let's plug in the value of y :
Answer:
c=2.22
Step-by-step explanation:
1/a- 1/b=1/c- 1/d
1/1/2- 1/1/4=1/c- 1/1/5
0.5-0.25=1/c- 0.2
0.25=1/c- 0.2
0.25+0.2=1/c
0.45=1/c
cross multiply
0.45×c=1
0.45c=1
divide both sides by 0.45
0.45c=1/0.45
c=2.22
So if the delievery man weighs 160 pounds and the books is 40 pounds. and the capacity he can carry is 950 then we have to figure out how many books a 160 can carry.
Division: 160/40=4
950/4=237.5
i tried to answer it. unless i try one more strategy.
Multiply: 160*40=6400
Divison: 6400/950= <span>6.73684210526
</span>try and round that huge number and figure it out. because i tried. im sorry. i hope you passed.
Answer:
The perpendicular line has a slope of -2/3
Step-by-step explanation:
Perpendicular lines have a slope that multiplies to -1
3/2 * m = -1
Multiply each side by 2/3
3/2 * 2/3 *m = -1 * 2/3
m = -2/3
Answer:
true because it have no common solution
