Answer:
Step-by-step explanation:
it makes 253 copies in 5 mins 45 seconds
that is to say, 253 copies in 345 seconds
In 1 minute (60 seconds) it will make X copies.
Lets draft an equation to easily express and simplify the problem.
253 copies = 345 seconds
X copies = 60 seconds
lets cross multiply and solve for X
Theefore:
x * 345 = 254 * 60
345x = 15,240
divide through by 345
x = 15240 / 345
x = 44.17
therefore, the copying machine makes approximately 44 copies per minutes

Step-by-step explanation:
Answer:
7.1
Step-by-step explanation:
write pythagorean theorem + =
2 = 100
divide 2 both side:
= 50
=
=
= 7.07106781
round to nearest tenth:
= 7.1
( x-5)/-2=(x-1)/-3
Cross multiply
-3(x-5)=-2(x-1)
Distribute
-3x +15 = -2x +2
Add 2x to both sides
-x +15 = 2
Subtract 15 from both sides
-x = -13
x=13
